Anisotropic organic single‐crystalline materials can induce abundant SOC phenomenon due to their flexible tunability of molecular geometries, however, the intrinsic relationship between molecular geometries/orientations in 3D space and photonic SOC is lacking. In this study, we design two kinds of 2D organic polymorphs for the construction of organic microcavities to investigate the structure‐performance relationships. In two polymorphic microcavities, two distinctive photonic SOC phenomena are observed regardless of the in‐plane anisotropy of organic polymorphs. Theoretical analysis indicates that the photonic SOC strength is strongly influenced by the synergies between the crystal anisotropy and the tilted collective molecular transition dipole moment. Our results uncover the correlation mechanism between the structure of molecules and photonic SOC and open an avenue to engineer complex photonic SOC by use of organic microstructures towards the development of diverse integrated photonic devices." article_number: e01874 author: - first_name: Ying full_name: Ji, Ying last_name: Ji - first_name: Xuekai full_name: Ma, Xuekai id: '59416' last_name: Ma - first_name: Han full_name: Huang, Han last_name: Huang - first_name: Yibo full_name: Deng, Yibo last_name: Deng - first_name: Pingyang full_name: Wang, Pingyang last_name: Wang - first_name: Teng full_name: Long, Teng last_name: Long - first_name: Yuan full_name: Li, Yuan last_name: Li - first_name: Ruiyang full_name: Zhao, Ruiyang last_name: Zhao - first_name: Yunfei full_name: Li, Yunfei last_name: Li - first_name: Cunbin full_name: An, Cunbin last_name: An - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 - first_name: Chunling full_name: Gu, Chunling last_name: Gu - first_name: Bo full_name: Liao, Bo last_name: Liao - first_name: Hongbing full_name: Fu, Hongbing last_name: Fu - first_name: Qing full_name: Liao, Qing last_name: Liao citation: ama: Ji Y, Ma X, Huang H, et al.

In this work, we observe the excitation of the vortices and realize tuning the topological charge by manipulating the pumping configurations. Using a digital micromirror device, we constructed an annular pumping pattern where the inner and outer rings can be easily tuned. Both the number and the topological charge of the vortices can be changed by slightly tuning the inner ring position against the outer ring. The experimental results can be reproduced in theory by the Gross–Pitaevskii equation. Our work offers to generate and manipulate vortices in exciton polariton condensates using a straightforward optical method. article_number: '121103' author: - first_name: Qiang full_name: Ai, Qiang last_name: Ai - first_name: Xuekai full_name: Ma, Xuekai id: '59416' last_name: Ma - first_name: Franziska full_name: Barkhausen, Franziska id: '63631' last_name: Barkhausen - first_name: Xiaokun full_name: Zhai, Xiaokun last_name: Zhai - first_name: Chunzi full_name: Xing, Chunzi last_name: Xing - first_name: Xinmiao full_name: Yang, Xinmiao last_name: Yang - first_name: Peilin full_name: Wang, Peilin last_name: Wang - first_name: Tianyu full_name: Liu, Tianyu last_name: Liu - first_name: Yong full_name: Zhang, Yong last_name: Zhang - first_name: Yazhou full_name: Gu, Yazhou last_name: Gu - first_name: Peigang full_name: Li, Peigang last_name: Li - first_name: Zhitong full_name: Li, Zhitong last_name: Li - first_name: Zacharias full_name: Hatzopoulos, Zacharias last_name: Hatzopoulos - first_name: Pavlos G. full_name: Savvidis, Pavlos G. last_name: Savvidis - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 - first_name: Tingge full_name: Gao, Tingge last_name: Gao citation: ama: Ai Q, Ma X, Barkhausen F, et al.

The progressive etching of the PLA film in direct contact with the nitrogen plasma was monitored in situ using polarization modulated infrared reflection absorption spectroscopy (PM‐IRRAS). No appreciative changes in composition were seen with PM‐IRRAS, indicating that the etching did not significantly affect the bulk composition. Atomic force microscopy characterization of the plasma‐etched films showed that the PLA films are homogeneously etched. Subsequent ex situ XPS analysis of the treated surface revealed the presence of C‐N bonds in the surface‐near region that could be associated with amino and/or amide surface species. PLA films were also alternatively exposed to nitrogen ion beams produced by an electron‐cyclotron‐resonance (ECR) plasma source and were investigated in vacuo by XPS. This treatment revealed the partial substitution of surface oxygen species by nitrogen, resulting in a similar surface modification as in the plasma case. The comparison of XPS data and water contact angle studies suggest that the activated surfaces show a reorientation of macromolecular fragments in the surface‐near region depending on the polarity of the phase with which they are in contact. Under ultra‐high vacuum (UHV) conditions, the surface tends to lower its surface energy, while in contact with the aqueous phase, subsurface polar groups orientate outwards, which enables the formation of hydrogen bonds." author: - first_name: Sandra full_name: Gołębiowska, Sandra last_name: Gołębiowska - first_name: Markus full_name: Voigt, Markus last_name: Voigt - first_name: Maria Teresa full_name: de los Arcos de Pedro, Maria Teresa id: '54556' last_name: de los Arcos de Pedro orcid: '0000-0002-8684-273X ' - first_name: Guido full_name: Grundmeier, Guido id: '194' last_name: Grundmeier citation: ama: Gołębiowska S, Voigt M, de los Arcos de Pedro MT, Grundmeier G.

A crucial step in realizing such large-scale quantum networks is the integration of entanglement distribution within existing telecommunication infrastructure. Here, we demonstrate a real-world scalable quantum networking testbed deployed within Deutsche Telekom’s metropolitan fibers in Berlin. Using commercially available quantum devices and standard add-drop multiplexing hardware, we distributed polarization-entangled photon pairs over dynamically selectable looped fiber paths ranging from 10 m to 60 km and showed entanglement distribution over up to approximately 100 km. Quantum signals, transmitted at 1324 nm (O-band), coexist with conventional bidirectional C-band traffic without dedicated fibers or infrastructure changes. Active stabilization of the polarization enables robust long-term performance, achieving entanglement Bell-state fidelity bounds between 85% and 99% and Clauser–Horne–Shimony–Holt parameter\r\n S\r\n -values between 2.36 and 2.74 during continuous multiday operation. By achieving a high-fidelity entanglement distribution with less than 1.5% downtime, we confirm the feasibility of hybrid quantum-classical networks under real-world conditions at the metropolitan scale. These results establish deployment benchmarks and provide a practical roadmap for telecom operators to integrate quantum capabilities.\r\n " article_number: '1072' author: - first_name: Matheus full_name: Sena, Matheus last_name: Sena - first_name: Mael full_name: Flament, Mael last_name: Flament - first_name: Shane full_name: Andrewski, Shane last_name: Andrewski - first_name: Ioannis full_name: Caltzidis, Ioannis last_name: Caltzidis - first_name: Niccolò full_name: Bigagli, Niccolò last_name: Bigagli - first_name: Thomas full_name: Rieser, Thomas last_name: Rieser - first_name: Gabriel full_name: Bello Portmann, Gabriel last_name: Bello Portmann - first_name: Rourke full_name: Sekelsky, Rourke last_name: Sekelsky - first_name: Ralf-Peter full_name: Braun, Ralf-Peter last_name: Braun - first_name: Alexander N. full_name: Craddock, Alexander N. last_name: Craddock - first_name: Maximilian full_name: Schulz, Maximilian last_name: Schulz - first_name: Klaus full_name: Jöns, Klaus id: '85353' last_name: Jöns - first_name: Michaela full_name: Ritter, Michaela last_name: Ritter - first_name: Marc full_name: Geitz, Marc last_name: Geitz - first_name: Oliver full_name: Holschke, Oliver last_name: Holschke - first_name: Mehdi full_name: Namazi, Mehdi last_name: Namazi citation: ama: Sena M, Flament M, Andrewski S, et al.

Our study examines the phase space representation of the system's eigenstates by comparing them to the classical phase space of a pendulum, to which the system effectively maps. The analysis reveals that quantum states can exhibit mixed dynamics by straddling the separatrix. A key finding is that the dynamics around the separatrix enables the controlled creation of highly nonclassical states, distinguishing them from the classical oscillatory or rotational dynamics of the pendulum. By considering a finite momentum of the initial wave packet, we demonstrate various dynamical regimes. Furthermore, a slight energy mismatch between nearly degenerate states localized at opposite turning points of the trap potential results in controlled long-range dynamical tunneling. These results can be interpreted as quantum beating between a clockwise rotating and a counterclockwise rotating pendulum. article_number: '013141' author: - first_name: Usman full_name: Ali, Usman last_name: Ali - first_name: Martin full_name: Holthaus, Martin last_name: Holthaus - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 citation: ama: 'Ali U, Holthaus M, Meier T.

Our theoretical approach is based on the formalism of Gaussian states and the Langevin equation, which is elaborated for weak parametric down-conversion and photon-number-unresolved click detection. Using the example of frequency-degenerate type-II SPDC generated under the pump-idler group-velocity-matching condition, we show how the joint-spectral intensity, mode structure, normalized second-order correlation function, and Hong-Ou-Mandel interference pattern depend on internal losses of the SPDC process. We found that the joint-spectral intensity is almost insensitive to internal losses, while the second-order correlation function shows a strong dependence on them, being different for the signal and idler beams in the presence of internal losses. Based on the sensitivity of the normalized second-order correlation function, we show how its measurement can be used to experimentally determine internal losses. article_number: '033122' author: - first_name: Denis A. full_name: Kopylov, Denis A. last_name: Kopylov - first_name: Michael full_name: Stefszky, Michael id: '42777' last_name: Stefszky - first_name: Torsten full_name: Meier, Torsten id: '344' last_name: Meier orcid: 0000-0001-8864-2072 - first_name: Christine full_name: Silberhorn, Christine id: '26263' last_name: Silberhorn - first_name: Polina R. full_name: Sharapova, Polina R. id: '60286' last_name: Sharapova citation: ama: 'Kopylov DA, Stefszky M, Meier T, Silberhorn C, Sharapova PR.

The comparably high mass of the muon (≈ 207 · me\r\n \ ) has two important effects, (i) the reduced mass of the system becomes more important, and (ii) the muon is localized much closer to the nucleus. Thus, muonic hydrogen is not only excellently suitable for evaluating highly precise quantum electrodynamic (QED) calculations, but may also be used for assessing new approaches including finite nuclear size (FNS) effects to evaluate the proton structure and improve calculation schemes for the hyperfine splittings of many-particle systems, as e.g. to be implemented in density functional theory (DFT) software packages. Here, starting from Dirac’s equation we calculate the relativistic hyperfine splitting of the ground state and several excited states of muonic hydrogen analytically for different charge and magnetization models. The FNS related hyperfine shifts are compared with the differences between QED calculations and experimental measurements. This comparison also allows to unravel the role of the reduced mass, which is on one hand crucial in case of muonic atoms, but on the other hand is by no means well defined in relativistic quantum mechanics." article_number: '012001' author: - first_name: Katharina L. full_name: Franzke, Katharina L. last_name: Franzke - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 - first_name: Uwe full_name: Gerstmann, Uwe id: '171' last_name: Gerstmann orcid: 0000-0002-4476-223X citation: ama: 'Franzke KL, Schmidt WG, Gerstmann U.

Here, a novel nucleophilic‐attack n‐doping mechanism is unveiled that achieves exceptionally high conductivity in doped OSC films and demonstrates broad applicability across OSCs. The remarkable efficacy of n‐Butyl lithium (n‐BuLi) is highlighted in n‐doping C\r\n 60\r\n \ and PC\r\n 61\r\n \ BM, achieving a conductivity of 1.27 S cm\r\n −1\r\n \ and 2.57 S cm\r\n −1\r\n \ , respectively, which are among the highest reported values for these materials. The investigation reveals that the n‐BuLi anion interacts with electron‐deficient units in OSCs, generating a carbanion that facilitates efficient electron transfer for n‐doping. This mechanism is further validated across diverse fullerenes, polymeric, and small molecule OSCs, and is extendable to other high‐performance dopants such as tert‐Butyllithium (tert‐BuLi) and sodium ethoxide (NaOEt). Device studies show that n‐BuLi‐doped C\r\n 60\r\n \ enables substantially improved diode rectification, attributed to greater junction built‐in potential. These findings establish a unified chemical‐bonding‐based n‐doping paradigm, complementing existing electrophilic‐attack p‐doping concepts, and pave the way for achieving efficient doping of OSCs for advanced organic electronic applications.\r\n " article_number: e20487 author: - first_name: Huan full_name: Wei, Huan last_name: Wei - first_name: Tong full_name: Wu, Tong last_name: Wu - first_name: Chuanding full_name: Dong, Chuanding last_name: Dong - first_name: Chen full_name: Chen, Chen last_name: Chen - first_name: Zhenqi full_name: Gong, Zhenqi last_name: Gong - first_name: Jiangnan full_name: Xia, Jiangnan last_name: Xia - first_name: Chengyuan full_name: Peng, Chengyuan last_name: Peng - first_name: Jiaqi full_name: Ding, Jiaqi last_name: Ding - first_name: Yu full_name: Zhang, Yu last_name: Zhang - first_name: Wenpei full_name: Shi, Wenpei last_name: Shi - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 - first_name: Xue full_name: Zhang, Xue last_name: Zhang - first_name: Yugang full_name: Bai, Yugang last_name: Bai - first_name: Lang full_name: Jiang, Lang last_name: Jiang - first_name: Lei full_name: Liao, Lei last_name: Liao - first_name: Thuc‐Quyen full_name: Nguyen, Thuc‐Quyen last_name: Nguyen - first_name: Yuanyuan full_name: Hu, Yuanyuan last_name: Hu citation: ama: Wei H, Wu T, Dong C, et al.

Going beyond isolated EPs, here we report on the existence of exceptional rings (ERs) in planar optical resonators with specific form of circular dichroism and TE-TM splitting. Such exceptional rings possess intriguing topologies as discussed earlier for condensed matter systems, but they remain virtually unexplored in presence of nonlinearity, for which our photonic platform is ideal. We find that when Kerr-type nonlinearity (or saturable gain) is introduced, the linear ER splits into two concentric ERs, with the larger-radius ring being a ring of third-order EPs. Transitioning from linear to nonlinear regime, we present a rigorous analysis of spectral topology and report enhanced and adjustable perturbation response in the nonlinear regime. Whereas certain features are specific to our system, the results on non-Hermitian spectral topology and nonlinearity-enhanced perturbation response are generic and equally relevant to a broad class of other nonlinear non-Hermitian systems, providing a universal framework for engineering ERs and EPs in nonlinear non-Hermitian systems. author: - first_name: Jan full_name: Wingenbach, Jan id: '69187' last_name: Wingenbach - first_name: 'Laura ' full_name: 'Ares Santos, Laura ' last_name: Ares Santos - first_name: Xuekai full_name: Ma, Xuekai id: '59416' last_name: Ma - first_name: Jan full_name: Sperling, Jan id: '75127' last_name: Sperling orcid: 0000-0002-5844-3205 - first_name: Stefan full_name: Schumacher, Stefan id: '27271' last_name: Schumacher orcid: 0000-0003-4042-4951 citation: ama: Wingenbach J, Ares Santos L, Ma X, Sperling J, Schumacher S.

However, quantifying the density of such defects in thin hBN flakes has remained elusive, limiting progress in device integration and reproducibility. Here, an all‐optical method is presented to quantify \ defect density in hBN by correlating Raman and photoluminescence (PL) signatures with irradiation fluence. Two defect‐induced Raman modes, D1 and D2, are identified and assigned them to vibrational modes of using polarization‐resolved Raman measurements and density functional theory (DFT) calculations. By adapting a numerical model originally developed for graphene, an empirical relationship linking Raman (D1,\r\n \ E\r\n 2g\r\n \ ) and PL intensities is established to absolute defect densities. This method is universally applicable across various irradiation types and uniquely suited for thin flakes, where conventional techniques fail. The approach enables accurate, direct, and non‐destructive quantification of spin defect densities down to 10\r\n 15\r\n  defects/cm\r\n \ 3\r\n , offering a powerful tool for optimizing and benchmarking hBN for quantum optical applications.\r\n \ " article_number: e17851 author: - first_name: Atanu full_name: Patra, Atanu last_name: Patra - first_name: Paul full_name: Konrad, Paul last_name: Konrad - first_name: Andreas full_name: Sperlich, Andreas last_name: Sperlich - first_name: Timur full_name: Biktagirov, Timur id: '65612' last_name: Biktagirov - first_name: Wolf Gero full_name: Schmidt, Wolf Gero id: '468' last_name: Schmidt orcid: 0000-0002-2717-5076 - first_name: Lesley full_name: Spencer, Lesley last_name: Spencer - first_name: Igor full_name: Aharonovich, Igor last_name: Aharonovich - first_name: Sven full_name: Höfling, Sven last_name: Höfling - first_name: Vladimir full_name: Dyakonov, Vladimir last_name: Dyakonov citation: ama: Patra A, Konrad P, Sperlich A, et al.
