Besides the original parameter sets, some specifically reparametrized SQC methods (denoted as AM1-W, PM6-fm, and DFTB2-iBi) targeting various smaller water systems ranging from molecular clusters to bulk are considered as well. The quality of these different SQC methods for describing liquid water properties at ambient conditions are assessed by comparison to well-established experimental data and also to BLYP-D3 density functional theory-based ab initio MD simulations. Our analyses reveal that static and dynamics properties of bulk water are poorly described by all considered SQC methods with the original parameters, regardless of the underlying theoretical models, with most of the methods suffering from too weak hydrogen bonds and hence predicting a far too fluid water with highly distorted hydrogen bond kinetics. On the other hand, the reparametrized force-matchcd PM6-fm method is shown to be able to quantitatively reproduce the static and dynamic features of liquid water, and thus can be used as a computationally efficient alternative to electronic structure-based MD simulations for liquid water that requires extended length and time scales. DFTB2-iBi predicts a slightly overstructured water with reduced fluidity, whereas AM1-W gives an amorphous ice-like structure for water at ambient conditions.","lang":"eng"}],"department":[{"_id":"27"},{"_id":"2"}],"user_id":"77439","_id":"64071","project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"language":[{"iso":"eng"}]},{"status":"public","abstract":[{"lang":"eng","text":"Effective single-particle theories, such as Hartree–Fock, density functional theory, and tight-binding, are limited by the computational cost of the self-consistent field (SCF) procedure, which typically scales cubically with the system size. This makes large-scale applications impractical without specialized algorithms and hardware. Here, we present the submatrix and graphical processing unit (GPU)-accelerated software implementation of the PTB tight-binding potential, realized in the open-source ptb codebase [M. Mueller, A. Katbashev, and S. Ehlert (2025). “grimme-lab/ptb: v3.8.1,” Zenodo. https://zenodo.org/records/17015872]. We first benchmark a traditional diagonalization-based SCF solver against density-matrix-based purification approaches, systematically varying both system size and computer hardware. Our findings show that the usage of GPUs permits shifting the boundaries to much larger systems than previously thought feasible, achieving an overall 10–15-fold performance speedup. Second, we introduce the implementation of a decomposition-type submatrix method, specifically designed for efficient operation on mid- to large-sized systems, to address the computational overhead associated with full-system diagonalization. We demonstrate that, from a certain dimension (≈104 basis functions) on, our submatrix method reduces the overall computational cost while maintaining acceptable numerical accuracy. Our study demonstrates the significance of the interplay between modern hardware, algorithmic considerations, and novel tight-binding methods, paving the way for further development in this direction."}],"type":"journal_article","publication":"The Journal of Chemical Physics","language":[{"iso":"eng"}],"article_number":"132501","user_id":"75963","department":[{"_id":"27"}],"project":[{"name":"Computing Resources Provided by the Paderborn Center for Parallel Computing","_id":"52"}],"_id":"62034","citation":{"apa":"Katbashev, A., Schade, R., Laß, M., Müller, M., Grimme, S., Hansen, A., &#38; Kühne, T.

In practical simulations, several trillions of ERIs may have to be\r\ncomputed for every time step.\r\nIn this work, we investigate FPGAs as accelerators for the ERI computation. We use template parameters, here within the Intel oneAPI tool flow, to create customized designs for 256 different ERI quartet classes, based on their orbitals. To maximize data reuse, all intermediates are buffered in FPGA on-chip memory with customized layout. The pre-calculation of intermediates also helps to overcome data dependencies caused by multi-dimensional recurrence\r\nrelations. The involved loop structures are partially or even fully unrolled for high throughput of FPGA kernels. Furthermore, a lossy compression algorithm utilizing arbitrary bitwidth integers is integrated in the FPGA kernels. To our\r\nbest knowledge, this is the first work on ERI computation on FPGAs that supports more than just the single most basic quartet class. Also, the integration of ERI computation and compression it a novelty that is not even covered by CPU or GPU libraries so far.\r\nOur evaluation shows that using 16-bit integer for the ERI compression, the fastest FPGA kernels exceed the performance of 10 GERIS ($10 \\times 10^9$ ERIs per second) on one Intel Stratix 10 GX 2800 FPGA, with maximum absolute errors around $10^{-7}$ - $10^{-5}$ Hartree. The measured throughput can be accurately explained by a performance model. The FPGA kernels deployed on 2 FPGAs outperform similar computations using the widely used libint reference on a two-socket server with 40 Xeon Gold 6148 CPU cores of the same process technology by factors up to 6.0x and on a new two-socket server with 128 EPYC 7713 CPU cores by up to 1.9x."}],"status":"public","publication":"2023 IEEE 31st Annual International Symposium on Field-Programmable Custom Computing Machines (FCCM)","type":"conference","language":[{"iso":"eng"}],"external_id":{"arxiv":["2303.13632"]},"_id":"43228","project":[{"_id":"52","name":"PC2: Computing Resources Provided by the Paderborn Center for Parallel Computing"}],"department":[{"_id":"27"},{"_id":"518"}],"user_id":"75963","year":"2023","page":"162-173","citation":{"chicago":"Wu, Xin, Tobias Kenter, Robert Schade, Thomas Kühne, and Christian Plessl. “Computing and Compressing Electron Repulsion Integrals on FPGAs.” In <i>2023 IEEE 31st Annual International Symposium on Field-Programmable Custom Computing Machines (FCCM)</i>, 162–73, 2023. <a href=\"https://doi.org/10.1109/FCCM57271.2023.00026\">https://doi.org/10.1109/FCCM57271.2023.00026</a>.","ieee":"X.

However, the electron transfer mechanisms from the photosensitizer to the proton reduction catalyst in base metal dyads remain so far unexplored. We study a Fe-Co dyad that exhibits photocatalytic H2 production activity using femtosecond X-ray emission spectroscopy, complemented by ultrafast optical spectroscopy and theoretical time-dependent DFT calculations, to understand the electronic and structural dynamics after photoexcitation and during the subsequent charge transfer process from the FeII photosensitizer to the cobaloxime catalyst. Using this novel approach, the simultaneous measurement of the transient Kalpha X-ray emission at the iron and cobalt K-edges in a two-colour experiment is enabled making it possible to correlate the excited state dynamics to the electron transfer processes. The methodology, therefore, provides a clear and direct spectroscopic evidence of the Fe->Co electron transfer responsible for the proton reduction activity.","lang":"eng"}],"type":"preprint","publication":"arxiv"},{"doi":"10.1038/s41557-022-00977-2","title":"Time-resolved terahertz–Raman spectroscopy reveals that cations and anions distinctly modify intermolecular interactions of water","volume":14,"date_created":"2022-12-09T11:26:57Z","author":[{"first_name":"Vasileios","last_name":"Balos","full_name":"Balos, Vasileios"},{"full_name":"Kaliannan, Naveen Kumar","last_name":"Kaliannan","first_name":"Naveen Kumar"},{"id":"60250","full_name":"Elgabarty, Hossam","orcid":"0000-0002-4945-1481","last_name":"Elgabarty","first_name":"Hossam"},{"first_name":"Martin","full_name":"Wolf, Martin","last_name":"Wolf"},{"last_name":"Kühne","id":"49079","full_name":"Kühne, Thomas","first_name":"Thomas"},{"last_name":"Sajadi","full_name":"Sajadi, Mohsen","first_name":"Mohsen"}],"date_updated":"2022-12-09T12:22:40Z","publisher":"Springer Science and Business Media LLC","intvolume":"        14","page":"1031-1037","citation":{"chicago":"Balos, Vasileios, Naveen Kumar Kaliannan, Hossam Elgabarty, Martin Wolf, Thomas Kühne, and Mohsen Sajadi. “Time-Resolved Terahertz–Raman Spectroscopy Reveals That Cations and Anions Distinctly Modify Intermolecular Interactions of Water.” <i>Nature Chemistry</i> 14, no. 9 (2022): 1031–37. <a href=\"https://doi.org/10.1038/s41557-022-00977-2\">https://doi.org/10.1038/s41557-022-00977-2</a>.","ieee":"V.

Here we provide microscopic insights into this process by monitoring the dissipation of energy in salt solutions using time-resolved terahertz–Raman spectroscopy. We resonantly drive the low-frequency rotational dynamics of water molecules using intense terahertz pulses and probe the Raman response of their intermolecular translational motions. We find that the intermolecular rotational-to-translational energy transfer is enhanced by highly charged cations and is drastically reduced by highly charged anions, scaling with the ion surface charge density and ion concentration. Our molecular dynamics simulations reveal that the water–water hydrogen-bond strength between the first and second solvation shells of cations increases, while it decreases around anions. The opposite effects of cations and anions on the intermolecular interactions of water resemble the effects of ions on the stabilization and denaturation of proteins.</jats:p>","lang":"eng"}],"publication":"Nature Chemistry","type":"journal_article"},{"date_updated":"2022-10-11T08:12:43Z","publisher":"American Physical Society (APS)","volume":105,"date_created":"2022-10-11T08:12:23Z","author":[{"last_name":"Zhang","full_name":"Zhang, Ruiming","first_name":"Ruiming"},{"full_name":"Ruan, Wei","last_name":"Ruan","first_name":"Wei"},{"first_name":"Junyao","full_name":"Yu, Junyao","last_name":"Yu"},{"full_name":"Gao, Libo","last_name":"Gao","first_name":"Libo"},{"last_name":"Berger","full_name":"Berger, Helmuth","first_name":"Helmuth"},{"first_name":"László","full_name":"Forró, László","last_name":"Forró"},{"full_name":"Watanabe, Kenji","last_name":"Watanabe","first_name":"Kenji"},{"full_name":"Taniguchi, Takashi","last_name":"Taniguchi","first_name":"Takashi"},{"last_name":"Ranjbar","full_name":"Ranjbar, Ahmad","first_name":"Ahmad"},{"first_name":"Rodion V.","last_name":"Belosludov","full_name":"Belosludov, Rodion V."},{"id":"49079","full_name":"Kühne, Thomas","last_name":"Kühne","first_name":"Thomas"},{"last_name":"Bahramy","full_name":"Bahramy, Mohammad Saeed","first_name":"Mohammad Saeed"},{"last_name":"Xi","full_name":"Xi, Xiaoxiang","first_name":"Xiaoxiang"}],"title":"Second-harmonic generation in atomically thin <mml:math xmlns:mml=\"http://www.w3.org/1998/Math/MathML\"><mml:mn>1</mml:mn><mml:mi>T</mml:mi><mml:mtext>−</mml:mtext><mml:mi>Ti</mml:mi><mml:msub><mml:mrow><mml:mi>Se</mml:mi></mml:mrow><mml:mn>2</mml:mn></mml:msub></mml:math> and its possible origin from charge density wave transitions","doi":"10.1103/physrevb.105.085409","publication_identifier":{"issn":["2469-9950","2469-9969"]},"publication_status":"published","issue":"8","year":"2022","intvolume":"       105","citation":{"ama":"Zhang R, Ruan W, Yu J, et al.

The mechanisms behind the enhanced reactivity On-Water are not yet clear. In this work we use a Langevin scheme in the spirit of second generation Car-Parrinello to accelerate the second-order density functional Tight-Binding (DFTB2) method in order to investigate the free energy of two Diels-Alder reaction On-Water: the cycloaddition between cyclopentadiene and ethyl cinnamate or thionocinnamate. The only difference between the reactants is the substitution of a carbonyl oxygen for a thiocarbonyl sulfur, making possible the distinction between them as strong and weak hydrogen-bond acceptors. We find a different mechanism for the reaction during the transition states and uncover the role of hydrogen bonds along with the reaction path. Our results suggest that acceleration of Diels-Alder reactions do not arise from an increased number of hydrogen bonds at the transition state and charge transfer plays a significant role. However, the presence of water and hydrogen-bonds is determinant for the catalysis of these reactions.</jats:p>"}],"type":"preprint"},{"publisher":"American Physical Society (APS)","date_updated":"2022-10-11T08:14:01Z","volume":105,"date_created":"2022-10-11T08:13:47Z","author":[{"first_name":"Ehsan Rahmatizad","full_name":"Khajehpasha, Ehsan Rahmatizad","last_name":"Khajehpasha"},{"first_name":"Jonas A.","last_name":"Finkler","full_name":"Finkler, Jonas A."},{"first_name":"Thomas","last_name":"Kühne","id":"49079","full_name":"Kühne, Thomas"},{"first_name":"Alireza","full_name":"Ghasemi, Alireza","id":"77282","last_name":"Ghasemi"}],"title":"CENT2: Improved charge equilibration via neural network technique","doi":"10.1103/physrevb.105.144106","publication_identifier":{"issn":["2469-9950","2469-9969"]},"publication_status":"published","issue":"14","year":"2022","intvolume":"       105","citation":{"short":"E.R.

The films were differentiated in terms of porosity and roughness. The XPS N1s core levels of the N2 gas in presence of the SiO2 samples showed variations in width, binding energy and line shape. The width correlated with the surface charge induced in the dielectric films upon X-ray irradiation. The observed different binding energies observed for the N1s peak can only partly be associated with intrinsic work function differences between the samples, opening the possibility that the effect of physisorption at room temperature could be detected by a shift in the measured binding energy. However, the signals also show an increasing asymmetry with rising surface charge. This might be associated with the formation of vertical electrical gradients within the dielectric porous thin films, which complicates the assignment of binding energy positions to specific surface-related effects. With the support of Monte Carlo and first principles density functional theory calculations, the observed shifts were discussed in terms of the possible formation of transitory dipoles upon N2 physisorption within the porous SiO2 films.","lang":"eng"}],"status":"public","type":"journal_article","publication":"Applied Surface Science","article_number":"154525","article_type":"original","keyword":["Surfaces","Coatings and Films","Condensed Matter Physics","Surfaces and Interfaces","General Physics and Astronomy","General Chemistry"],"language":[{"iso":"eng"}],"_id":"33691","user_id":"23547","department":[{"_id":"613"},{"_id":"35"},{"_id":"2"},{"_id":"307"},{"_id":"302"},{"_id":"304"}]},{"volume":9,"author":[{"first_name":"Christian","full_name":"Weinberger, Christian","id":"11848","last_name":"Weinberger"},{"first_name":"Frederik","last_name":"Zysk","id":"14757","full_name":"Zysk, Frederik"},{"last_name":"Hartmann","full_name":"Hartmann, Marc","first_name":"Marc"},{"first_name":"Naveen","last_name":"Kaliannan","full_name":"Kaliannan, Naveen"},{"first_name":"Waldemar","last_name":"Keil","full_name":"Keil, Waldemar"},{"id":"49079","full_name":"Kühne, Thomas","last_name":"Kühne","first_name":"Thomas"},{"first_name":"Michael","last_name":"Tiemann","orcid":"0000-0003-1711-2722","full_name":"Tiemann, Michael","id":"23547"}],"date_updated":"2023-03-03T11:33:24Z","oa":"1","doi":"10.1002/admi.202200245","main_file_link":[{"url":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/admi.202200245","open_access":"1"}],"publication_identifier":{"issn":["2196-7350","2196-7350"]},"publication_status":"published","intvolume":"         9","citation":{"ieee":"C.

This leads to a different behavior regarding the molecular orientational freedom (‘structure of water') compared to the bulk liquid state. In addition to the pore size, the behavior is also strongly affected by the strength of the pore wall-to-water interactions, that is, the pore wall polarity. In this work, this is studied both experimentally and theoretically. The surface polarity of mesoporous silica (SiO2) is modified by functionalization with trimethylsilyl moieties, resulting in a change from a hydrophilic (pristine) to a hydrophobic pore wall. The mesopore surface is characterized by N2 and H2O sorption experiments. Those results are combined with IR spectroscopy to investigate pore wall-to-water interactions leading to different structures of water in the mesopore. Furthermore, the water's structure is studied theoretically to gain deeper insight into the interfacial interactions. For this purpose, the structure of water is analyzed by pairing densities, coordination, and angular distributions with a novel adaptation of surface-specific sum-frequency generation calculation for pore environments.","lang":"eng"}]},{"date_created":"2022-09-28T05:25:10Z","author":[{"first_name":"Vikram","full_name":"Gavini, Vikram","last_name":"Gavini"},{"full_name":"Baroni, Stefano","last_name":"Baroni","first_name":"Stefano"},{"first_name":"Volker","last_name":"Blum","full_name":"Blum, Volker"},{"full_name":"Bowler, David R.","last_name":"Bowler","first_name":"David R."},{"first_name":"Alexander","full_name":"Buccheri, Alexander","last_name":"Buccheri"},{"first_name":"James R.","last_name":"Chelikowsky","full_name":"Chelikowsky, James R."},{"full_name":"Das, Sambit","last_name":"Das","first_name":"Sambit"},{"full_name":"Dawson, William","last_name":"Dawson","first_name":"William"},{"last_name":"Delugas","full_name":"Delugas, Pietro","first_name":"Pietro"},{"first_name":"Mehmet","last_name":"Dogan","full_name":"Dogan, Mehmet"},{"first_name":"Claudia","full_name":"Draxl, Claudia","last_name":"Draxl"},{"full_name":"Galli, Giulia","last_name":"Galli","first_name":"Giulia"},{"first_name":"Luigi","full_name":"Genovese, Luigi","last_name":"Genovese"},{"first_name":"Paolo","last_name":"Giannozzi","full_name":"Giannozzi, Paolo"},{"full_name":"Giantomassi, Matteo","last_name":"Giantomassi","first_name":"Matteo"},{"full_name":"Gonze, Xavier","last_name":"Gonze","first_name":"Xavier"},{"last_name":"Govoni","full_name":"Govoni, Marco","first_name":"Marco"},{"first_name":"Andris","full_name":"Gulans, Andris","last_name":"Gulans"},{"first_name":"François","full_name":"Gygi, François","last_name":"Gygi"},{"first_name":"John M.","full_name":"Herbert, John M.","last_name":"Herbert"},{"first_name":"Sebastian","full_name":"Kokott, Sebastian","last_name":"Kokott"},{"last_name":"Kühne","id":"49079","full_name":"Kühne, Thomas","first_name":"Thomas"},{"last_name":"Liou","full_name":"Liou, Kai-Hsin","first_name":"Kai-Hsin"},{"last_name":"Miyazaki","full_name":"Miyazaki, Tsuyoshi","first_name":"Tsuyoshi"},{"last_name":"Motamarri","full_name":"Motamarri, Phani","first_name":"Phani"},{"first_name":"Ayako","last_name":"Nakata","full_name":"Nakata, Ayako"},{"last_name":"Pask","full_name":"Pask, John E.","first_name":"John E."},{"first_name":"Christian","full_name":"Plessl, Christian","id":"16153","last_name":"Plessl","orcid":"0000-0001-5728-9982"},{"last_name":"Ratcliff","full_name":"Ratcliff, Laura E.","first_name":"Laura E."},{"last_name":"Richard","full_name":"Richard, Ryan M.","first_name":"Ryan M."},{"first_name":"Mariana","last_name":"Rossi","full_name":"Rossi, Mariana"},{"orcid":"0000-0002-6268-539","last_name":"Schade","id":"75963","full_name":"Schade, Robert","first_name":"Robert"},{"first_name":"Matthias","last_name":"Scheffler","full_name":"Scheffler, Matthias"},{"first_name":"Ole","full_name":"Schütt, Ole","last_name":"Schütt"},{"first_name":"Phanish","last_name":"Suryanarayana","full_name":"Suryanarayana, Phanish"},{"full_name":"Torrent, Marc","last_name":"Torrent","first_name":"Marc"},{"last_name":"Truflandier","full_name":"Truflandier, Lionel","first_name":"Lionel"},{"first_name":"Theresa L.","full_name":"Windus, Theresa L.","last_name":"Windus"},{"first_name":"Qimen","full_name":"Xu, Qimen","last_name":"Xu"},{"first_name":"Victor W. -Z.","full_name":"Yu, Victor W. -Z.","last_name":"Yu"},{"first_name":"Danny","last_name":"Perez","full_name":"Perez, Danny"}],"date_updated":"2023-07-28T08:03:41Z","title":"Roadmap on Electronic Structure Codes in the Exascale Era","citation":{"short":"V.
