In order to further investigate its complexity and the potential of quantum algorithms for quantum chemistry, Gharibian and Le Gall (STOC 2022) recently introduced the guided local Hamiltonian problem (GLH), which is a variant of the local Hamiltonian problem where an approximation of a ground state is given as an additional input. Gharibian and Le Gall showed quantum advantage (more precisely, BQP-completeness) for GLH with $6$-local Hamiltonians when the guiding vector has overlap (inverse-polynomially) close to 1/2 with a ground state. In this paper, we optimally improve both the locality and the overlap parameters: we show that this quantum advantage (BQP-completeness) persists even with 2-local Hamiltonians, and even when the guiding vector has overlap (inverse-polynomially) close to 1 with a ground state. Moreover, we show that the quantum advantage also holds for 2-local physically motivated Hamiltonians on a 2D square lattice. This makes a further step towards establishing practical quantum advantage in quantum chemistry.}}, author = {{Gharibian, Sevag and Hayakawa, Ryu and Gall, François Le and Morimae, Tomoyuki}}, booktitle = {{Proceedings of the 50th EATCS International Colloquium on Automata, Languages and Programming (ICALP)}}, number = {{32}}, pages = {{1--19}}, title = {{{Improved Hardness Results for the Guided Local Hamiltonian Problem}}}, doi = {{10.4230/LIPIcs.ICALP.2023.32}}, volume = {{261}}, year = {{2023}}, } @article{47868, author = {{Tenberge, Claudia}}, journal = {{Grundschule Sachunterricht}}, pages = {{28--34}}, title = {{{Ungeliebte Tiere in der Stadt}}}, volume = {{98}}, year = {{2023}}, } @book{47885, editor = {{Vidita Urboniene , • Athanasios Christopoulos, Aušra Pažeraite, Christos Chytas, Claudia Tenberge, Djurdja Timotijevic, Dobrivoje Lale Eric, Egle Vaivadiene, Felix Winkelnkemper, Gabrielė Stupurienė, Gražina Šmitienė, Heidi Kaarto, Ingrida Mereckaite, Julija Grigorjevaite, Kadri Mettis, Katarina Stekic, Kristof Van de Keere, Marjana Brkic, Michael Lenke, Mikko-Jussi Laakso, Paulius Lukas Tamošiūnas, Sofia Karlsson, Sven Hüsing, Jurga Turčinavičienė, Violeta Šlekienė, Mart Laanpere, and Vidita Urboniene }}, publisher = {{online}}, title = {{{A PRACTICAL HANDBOOK ON EFFECTIVE DEVELOPMENT AND IMPLEMENTATION OF STEAM TEACHING AT SCHOOL}}}, year = {{2023}}, } @article{47992, abstract = {{Ferroelectric domain boundaries are quasi-two-dimensional functional interfaces with high prospects for nanoelectronic applications.

Here, the impact of the three-dimensional (3D) curvature on the polarization profile of nominally uncharged 180° domain walls in LiNbO3 is studied using second-harmonic generation microscopy and 3D polarimetry analysis. Correlations between the domain-wall curvature and the variation of its internal polarization unfold in the form of modulations of the Néel-like character, which we attribute to the flexoelectric effect. While the Néel-like character originates mainly from the tilting of the domain wall, the internal polarization adjusts its orientation due to the synergetic upshot of dipolar and monopolar bound charges and their variation with the 3D curvature.

Moreover, strain plays a key role, e.g., in the physics of ferroelectrics and, in particular, of their domain walls. μ-Raman spectroscopy is a well-suited technique for the investigation of such strain effects as it allows to measure the lattice dynamics locally. However, quantifying and reconstructing strain fields from Raman maps requires knowledge on the strain dependence of phonon frequencies. In this paper, we have analyzed both theoretically and experimentally the phonon frequencies in the widely used ferroelectrics lithium niobate and lithium tantalate as a function of uniaxial strain via density functional theory and μ-Raman spectroscopy. Overall, we find a good agreement between our ab initio models and the experimental data performed with a stress cell. The majority of phonons show an increase in frequency under compressive strain, whereas the opposite is observed for tensile strains. Moreover, for E-type phonons, we observe the lifting of degeneracy already at moderate strain fields (i.e., at ±0.2%) along the x and y directions. This paper, hence, allows for the systematic analysis of three-dimensional strains in modern-type bulk and thin-film devices assembled from lithium niobate and tantalate.}}, author = {{Singh, Ekta and Pionteck, Mike N. and Reitzig, Sven and Lange, Michael and Rüsing, Michael and Eng, Lukas M. and Sanna, Simone}}, issn = {{2475-9953}}, journal = {{Physical Review Materials}}, keywords = {{Physics and Astronomy (miscellaneous), General Materials Science}}, number = {{2}}, publisher = {{American Physical Society (APS)}}, title = {{{Vibrational properties of LiNbO3 and LiTaO3 under uniaxial stress}}}, doi = {{10.1103/physrevmaterials.7.024420}}, volume = {{7}}, year = {{2023}}, } @article{47994, abstract = {{Coherent nonlinear optical μ-spectroscopy is a frequently used tool in modern material science as it is sensitive to many different local observables, which comprise, among others, crystal symmetry and vibrational properties. The richness in information, however, may come with challenges in data interpretation, as one has to disentangle the many different effects like multiple reflections, phase jumps at interfaces, or the influence of the Guoy-phase. In order to facilitate interpretation, the work presented here proposes an easy-to-use semi-analytical modeling Ansatz, which bases upon known analytical solutions using Gaussian beams. Specifically, we apply this Ansatz to compute nonlinear optical responses of (thin film) optical materials. We try to conserve the meaning of intuitive parameters like the Gouy-phase and the nonlinear coherent interaction length. In particular, the concept of coherence length is extended, which is a must when using focal beams. The model is subsequently applied to exemplary cases of second- and third-harmonic generation. We observe a very good agreement with experimental data, and furthermore, despite the constraints and limits of the analytical Ansatz, our model performs similarly well as when using more rigorous simulations. However, it outperforms the latter in terms of computational power, requiring more than three orders less computational time and less performant computer systems.}}, author = {{Spychala, Kai J. and Amber, Zeeshan H. and Eng, Lukas M. and Rüsing, Michael}}, issn = {{0021-8979}}, journal = {{Journal of Applied Physics}}, keywords = {{General Physics and Astronomy}}, number = {{12}}, publisher = {{AIP Publishing}}, title = {{{Modeling nonlinear optical interactions of focused beams in bulk crystals and thin films: A phenomenological approach}}}, doi = {{10.1063/5.0136252}}, volume = {{133}}, year = {{2023}}, } @article{48013, author = {{Liu, Ping and Schumann, Nils and Abele, Fabian and Ren, Fazheng and Hanke, Marcel and Xin, Yang and Hartmann, Andreas and Schlierf, Michael and Keller, Adrian and Lin, Weilin and Zhang, Yixin}}, issn = {{2574-0970}}, journal = {{ACS Applied Nano Materials}}, keywords = {{General Materials Science}}, publisher = {{American Chemical Society (ACS)}}, title = {{{Thermophoretic Analysis of Biomolecules across the Nanoscales in Self-Assembled Polymeric Matrices}}}, doi = {{10.1021/acsanm.3c03623}}, year = {{2023}}, } @inbook{46561, author = {{Schuster, Britt-Marie}}, booktitle = {{Kommunikative Praktiken im Nationalsozialismus}}, editor = {{Markewitz, Friedrich and Scholl, Stefan and Schubert, Katrin and Wilk, Nicole M.}}, isbn = {{9783847116127}}, keywords = {{Kommunikationsgeschichte}}, pages = {{143–171}}, publisher = {{V&R unipress}}, title = {{{»Das dankst du deinem Führer« – Adressierungspraktiken in der Widerstandskommunikation gegen den Nationalsozialismus}}}, doi = {{10.14220/9783737016124}}, volume = {{3}}, year = {{2023}}, } @book{48043, editor = {{Schuster, Britt-Marie and Markewitz, Friedrich and Wilk, Nicole M.}}, title = {{{Widerstandshandeln.
