These features suggest electro-optic-based devices as candidates for entangled optical frequency comb sources. In the present work, I study the generation of entangled optical frequency combs in millimeter-sized resonant electro-optic modulators. These devices profit from the experimentally proven advantages such as nearly constant optical free spectral ranges over several gigahertz, and high optical and microwave quality factors. The generation of frequency multiplexed quantum channels with spectral bandwidth in the MHz range for conservative parameter values paves the way towards novel uses in long-distance hybrid quantum networks, quantum key distribution, enhanced optical metrology, and quantum computing.","lang":"eng"}],"user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","article_type":"original","fulldoi":"https://doi.org/10.1103/PhysRevA.103.023708","date_published":"2021-02-11T00:00:00Z","oa_version":"Preprint","_id":"9242","status":"public","publisher":"American Physical Society","acknowledgement":"I thank Prof. Shabir Barzanjeh and Dr. Ulrich Vogl for the fruitful discussions.\r\n","citation":{"chicago":"Rueda Sanchez, Alfredo R. “Frequency-Multiplexed Hybrid Optical Entangled Source Based on the Pockels Effect.” <i>Physical Review A</i>.

In the low-temperature regime we reproduce the recent measurements [Phys. Rev.

Conversely, a heat perturbation excites only the second sound, which, being sensitive to the superfluid depletion, vanishes in the deep BCS regime and jumps discontinuously to zero at the Berezinskii-Kosterlitz-Thouless superfluid transition. A mixing between the modes occurs only in the finite-temperature BEC regime, where our theory converges to the purely bosonic results."}],"date_updated":"2025-07-10T12:01:58Z","issue":"6","external_id":{"arxiv":["2009.06491"],"isi":["000662296700014"]},"intvolume":"       103","isi":1,"arxiv":1,"day":"01","publisher":"American Physical Society","citation":{"chicago":"Tononi, A., Alberto Cappellaro, Giacomo Bighin, and L.

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."}],"ec_funded":1,"date_updated":"2026-10-02T11:36:06Z","date_published":"2021-12-14T00:00:00Z","article_type":"original","fulldoi":"https://doi.org/10.1103/physreva.104.062423","arxiv":1,"day":"14","isi":1,"acknowledgement":"We would like to thank S.

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."}],"ddc":["530"],"date_published":"2020-12-14T00:00:00Z","has_accepted_license":"1","fulldoi":"https://doi.org/10.1103/physreva.102.063316","article_type":"original","tmp":{"image":"/images/cc_by.png","short":"CC BY (4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)"},"status":"public","_id":"18194","oa_version":"Published Version","day":"14","arxiv":1,"year":"2020","citation":{"ama":"Repellin C, Leonard J, Goldman N.

In this work, an ensemble of 500000 spin-squeezed atoms in a high-finesse optical cavity with near-uniform atom-cavity coupling is prepared, released into free space, recaptured in the cavity, and probed. Up to ∼10 dB of metrologically relevant squeezing is retrieved for 700μs free-fall times, and decaying levels of squeezing are realized for up to 3 ms free-fall times. The degradation of squeezing results from loss of atom-cavity coupling homogeneity between the initial squeezed state generation and final collective state readout.

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.

Is there any delay between electrons originating from the same electronic shell but leaving the cation in different fine-structure states? This question is relevant for all attosecond photoemission studies involving heavy elements, be it atoms, molecules or solids. 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. Our results show an important influence of spin-orbit coupling on attosecond photoionization delays, highlight the requirement for additional theory development, and offer a precision benchmark for such work.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","date_updated":"2023-08-22T08:38:17Z","fulldoi":"https://doi.org/10.1103/physreva.95.013404","article_type":"original","date_published":"2017-01-10T00:00:00Z","month":"01","language":[{"iso":"eng"}],"volume":95,"publication_status":"published","quality_controlled":"1","date_created":"2023-08-10T06:36:58Z","article_processing_charge":"No","author":[{"first_name":"I.","last_name":"Jordan","full_name":"Jordan, I."},{"first_name":"M.","full_name":"Huppert, M.","last_name":"Huppert"},{"first_name":"S.","full_name":"Pabst, S.","last_name":"Pabst"},{"last_name":"Kheifets","full_name":"Kheifets, A.

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"}],"ec_funded":1,"date_updated":"2026-07-07T13:17:34Z","publist_id":"6305","date_published":"2017-02-01T00:00:00Z","fulldoi":"https://doi.org/10.1103/PhysRevA.95.023403","month":"02","publication_status":"published","language":[{"iso":"eng"}],"department":[{"_id":"MiLe"}],"volume":95,"project":[{"grant_number":"291734","_id":"25681D80-B435-11E9-9278-68D0E5697425","name":"International IST Postdoc Fellowship Programme","call_identifier":"FP7"}],"quality_controlled":"1","article_processing_charge":"No","date_created":"2018-12-11T11:50:01Z","publication":"Physical Review A","author":[{"first_name":"Michael","full_name":"Klaiber, Michael","last_name":"Klaiber"},{"first_name":"Jiří","last_name":"Daněk","full_name":"Daněk, Jiří"},{"first_name":"Enderalp","orcid":"0000-0001-5973-0874","last_name":"Yakaboylu","id":"38CB71F6-F248-11E8-B48F-1D18A9856A87","full_name":"Yakaboylu, Enderalp"},{"first_name":"Karen","full_name":"Hatsagortsyan, Karen","last_name":"Hatsagortsyan"},{"full_name":"Keitel, Christoph","last_name":"Keitel","first_name":"Christoph"}],"scopus_import":"1","article_number":"023403","oa":1,"title":"Strong-field ionization via a high-order Coulomb-corrected strong-field approximation","publication_identifier":{"issn":["2469-9926"]},"type":"journal_article","doi":"10.1103/PhysRevA.95.023403","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/1609.07018"}]},{"page":"023612 - 1-0236121-2","volume":70,"language":[{"iso":"eng"}],"publication_status":"published","month":"08","date_created":"2018-12-11T11:57:12Z","article_processing_charge":"No","publication":"Physical Review A - Atomic, Molecular, and Optical Physics","author":[{"first_name":"Michael","full_name":"Aizenman, Michael","last_name":"Aizenman"},{"full_name":"Lieb, Élliott","last_name":"Lieb","first_name":"Élliott"},{"orcid":"0000-0002-6781-0521","first_name":"Robert","id":"4AFD0470-F248-11E8-B48F-1D18A9856A87","last_name":"Seiringer","full_name":"Seiringer, Robert"},{"last_name":"Solovej","full_name":"Solovej, Jan","first_name":"Jan"},{"first_name":"Jakob","full_name":"Yngvason, Jakob","last_name":"Yngvason"}],"publication_identifier":{"issn":["2469-9926"],"eissn":["2469-9934"]},"title":"Bose-Einstein quantum phase transition in an optical lattice model","oa":1,"doi":"10.1103/PhysRevA.70.023612","main_file_link":[{"open_access":"1","url":"http://arxiv.org/abs/cond-mat/0403240"}],"type":"journal_article","extern":"1","status":"public","_id":"2360","oa_version":"None","day":"01","arxiv":1,"year":"2004","citation":{"ista":"Aizenman M, Lieb É, Seiringer R, Solovej J, Yngvason J. 2004.

It was found that the system was a hard core lattice gas at half of the maximum density and the optical lattice was modeled by a periodic potential of strength λ. It was also observed that the interparticle interaction was essential for this transition that occurred even in the ground state. The results show that all the essential features could be proved rigorously such as the existence of BEC for small λ and its suppression for a large λ.","lang":"eng"}],"OA_type":"green","date_published":"2004-08-01T00:00:00Z","article_type":"original","fulldoi":"https://doi.org/10.1103/PhysRevA.70.023612","OA_place":"repository"}]
