Until now, many theoretical works studied the performance of quantum algorithms for models with a unique ground state. However, when the classical problem is in a so-called clustering phase, the ground state manifold is highly degenerate. As an example, we consider a 3-XORSAT model defined on simple hypergraphs. The degeneracy of classical ground state manifold translates into the emergence of an extensive number of Z2 symmetries, which remain intact even in the presence of a quantum transverse magnetic field. We establish a general duality approach that restricts the quantum problem to a given sector of conserved Z2 charges and use it to study how the outcome of the quantum adiabatic algorithm depends on the hypergraph geometry. We show that the tree hypergraph which corresponds to a classically solvable instance of the 3-XORSAT problem features a constant gap, whereas the closed hypergraph encounters a second-order phase transition with a gap vanishing as a power-law in the problem size. The duality developed in this work provides a practical tool for studies of quantum models with classically degenerate energy manifold and reveals potential connections between glasses and gauge theories."}],"arxiv":1,"type":"journal_article","month":"12","project":[{"call_identifier":"H2020","_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","grant_number":"850899"}],"external_id":{"isi":["000753659200004"],"arxiv":["2106.06344"]},"title":"Duality approach to quantum annealing of the 3-variable exclusive-or satisfiability problem (3-XORSAT)","main_file_link":[{"url":"https://arxiv.org/abs/2106.06344","open_access":"1"}],"article_processing_charge":"No","doi":"10.1103/physreva.104.062423","date_created":"2021-12-14T20:46:07Z","oa_version":"Preprint","department":[{"_id":"MaSe"}]},{"year":"2020","author":[{"full_name":"Repellin, C.","last_name":"Repellin","first_name":"C."},{"id":"b75b3f45-7995-11ef-9bfd-9a9cd02c3577","full_name":"Leonard, Julian","first_name":"Julian","last_name":"Leonard"},{"last_name":"Goldman","first_name":"N.","full_name":"Goldman, N."}],"extern":"1","date_updated":"2024-10-08T09:51:57Z","scopus_import":"1","has_accepted_license":"1","publisher":"American Physical Society","ddc":["530"],"article_number":"063316","citation":{"short":"C.

While fractional quantum Hall states could soon be implemented in small atomic ensembles, detecting their signatures in few-particle settings remains a fundamental challenge. In this work, we numerically analyze the center-of-mass Hall drift of a small ensemble of hardcore bosons, initially prepared in the ground state of the Harper-Hofstadter-Hubbard model in a box potential. By monitoring the Hall drift upon release, for a wide range of magnetic flux values, we identify an emergent Hall plateau compatible with a fractional Chern insulator state: The extracted Hall conductivity approaches a fractional value determined by the many-body Chern number, while the width of the plateau agrees with the spectral and topological properties of the prepared ground state. Besides, a direct application of Streda's formula indicates that such Hall plateaus can also be directly obtained from static density-profile measurements. Our calculations suggest that fractional Chern insulators can be detected in cold-atom experiments, using available detection methods.","lang":"eng"}],"type":"journal_article","arxiv":1,"month":"12","publication_identifier":{"issn":["2469-9926"],"eissn":["2469-9934"]}},{"article_number":"012224","citation":{"short":"Y.

Is there any delay between electrons originating from the same electronic shell but leaving the cation in different fine-structure states?

We answer this fundamental question by measuring energy-dependent delays between photoelectron wave packets associated with the 2P3/2 and 2P1/2 components of the electronic groundstates of Xe+ and Kr+. We observe delays reaching up to 33±6 as in the case of Xe. Our results are compared with two state-of-the-art theories. Whereas both theories quantitatively agree with the results obtained for Kr, neither of them fully reproduces the experimental results in Xe. Performing delay measurements very close to the ionization thresholds, we compare the agreement of several analytical formulas for the continuum-continuum delays with experimental data.

A high-order Coulomb-corrected strong-field approximation is applied, where the exact continuum state in the S matrix is approximated by the eikonal Coulomb-Volkov state including the second-order corrections to the eikonal. Although without high-order corrections our theory coincides with the known analytical R-matrix (ARM) theory, we propose a simplified procedure for the matrix element derivation. Rather than matching the eikonal Coulomb-Volkov wave function with the bound state as in the ARM theory to remove the Coulomb singularity, we calculate the matrix element via the saddle-point integration method by time as well as by coordinate, and in this way avoiding the Coulomb singularity. The momentum shift in the photoelectron momentum distribution with respect to the ARM theory due to high-order corrections is analyzed for tunneling and multiphoton regimes. The relation of the quantum corrections to the tunneling delay time is discussed.","lang":"eng"}],"month":"02","arxiv":1,"type":"journal_article","publication_identifier":{"issn":["2469-9926"]},"isi":1,"_id":"1076","date_published":"2017-02-01T00:00:00Z","language":[{"iso":"eng"}],"publist_id":"6305","publication_status":"published","intvolume":"        95","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","day":"01","issue":"2","volume":95,"oa":1,"quality_controlled":"1","year":"2017","author":[{"first_name":"Michael","last_name":"Klaiber","full_name":"Klaiber, Michael"},{"last_name":"Daněk","first_name":"Jiří","full_name":"Daněk, Jiří"},{"orcid":"0000-0001-5973-0874","id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","last_name":"Yakaboylu","first_name":"Enderalp","full_name":"Yakaboylu, Enderalp"},{"full_name":"Hatsagortsyan, Karen","last_name":"Hatsagortsyan","first_name":"Karen"},{"last_name":"Keitel","first_name":"Christoph","full_name":"Keitel, Christoph"}],"date_updated":"2025-06-04T08:11:30Z","ec_funded":1,"scopus_import":"1","publisher":"American Physical Society","citation":{"short":"M.

Here we reveal the self-localization transition for the rotational analogue of the polaron -- the angulon quasiparticle. We show that, unlike for the polarons, self-localization of angulons occurs at finite impurity-bath coupling already at the mean-field level. The transition is accompanied by the spherical-symmetry breaking of the angulon ground state and a discontinuity in the first derivative of the ground-state energy. Moreover, the type of the symmetry breaking is dictated by the symmetry of the microscopic impurity-bath interaction, which leads to a number of distinct self-localized states. The predicted effects can potentially be addressed in experiments on cold molecules trapped in superfluid helium droplets and ultracold quantum gases, as well as on electronic excitations in solids and Bose-Einstein condensates.

However, most of the studies of this radiation were performed on simple periodic gratings, whose radiation spectrum exhibits a single peak and its higher harmonics predicted by a well-established dispersion relation. Here, we propose a method to shape the spatial and spectral far-field distribution of the radiation using complex periodic and aperiodic gratings. We show, theoretically and experimentally, that engineering multiple peak spectra with controlled widths located at desired wavelengths is achievable using Smith-Purcell radiation.
