It is known, however, that the geometry and topology of space can have significant effects on quantum statistics for particles moving on it. Here, we have undertaken the first step toward realizing the emerging fractional statistics for particles restricted to move on the sphere instead of on the plane. We show that such a model arises naturally in the context of quantum impurity problems. In particular, we demonstrate a setup in which the lowest-energy spectrum of two linear bosonic or fermionic molecules immersed in a quantum many-particle environment can coincide with the anyonic spectrum on the sphere. This paves the way toward the experimental realization of anyons on the sphere using molecular impurities. Furthermore, since a change in the alignment of the molecules corresponds to the exchange of the particles on the sphere, such a realization reveals a novel type of exclusion principle for molecular impurities, which could also be of use as a powerful technique to measure the statistics parameter. Finally, our approach opens up a simple numerical route to investigate the spectra of many anyons on the sphere. Accordingly, we present the spectrum of two anyons on the sphere in the presence of a Dirac monopole field."}],"type":"journal_article","date_published":"2021-01-08T00:00:00Z","article_type":"original","citation":{"ama":"Brooks M, Lemeshko M, Lundholm D, Yakaboylu E.

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.","lang":"eng"}],"issue":"6","type":"journal_article","date_published":"2021-06-01T00:00:00Z","publication":"Physical Review A","citation":{"mla":"Tononi, A., et al. “Propagation of First and Second Sound in a Two-Dimensional Fermi Superfluid.” Physical Review A, vol. 103, no. 6, L061303, American Physical Society, 2021, doi:10.1103/PhysRevA.103.L061303.","short":"A.

Depending on the ratio κ of the impurity and fermion masses, the billiards can be integrable or non-integrable (also referred to in the main text as chaotic). To set the stage, we first investigate the energy level distributions of the billiards as a function of 1/κ ∈ [0, 1] and find no evidence of integrable cases beyond the limiting values 1/κ = 1 and 1/κ = 0. Then, we use machine learning tools to analyze properties of probability distributions of individual quantum states. We find that convolutional neural networks can correctly classify integrable and non-integrable states. The decisive features of the wave functions are the normalization and a large number of zero elements, corresponding to the existence of a nodal line. The network achieves typical accuracies of 97%, suggesting that machine learning tools can be used to analyze and classify the morphology of probability densities obtained in theory or experiment.","lang":"eng"}],"issue":"6","type":"journal_article","oa_version":"Published Version","file":[{"file_size":3868445,"content_type":"application/pdf","creator":"cziletti","file_name":"2021_NewJPhys_Huber.pdf","access_level":"open_access","date_created":"2021-07-19T11:47:16Z","date_updated":"2021-07-19T11:47:16Z","checksum":"e39164ce7ea228d287cf8924e1a0f9fe","success":1,"relation":"main_file","file_id":"9690"}],"status":"public","title":"Morphology of three-body quantum states from machine learning","ddc":["530"],"intvolume":" 23","_id":"9679","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","month":"06","publication_identifier":{"eissn":["13672630"]},"language":[{"iso":"eng"}],"doi":"10.1088/1367-2630/ac0576","quality_controlled":"1","isi":1,"project":[{"name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020","_id":"260C2330-B435-11E9-9278-68D0E5697425","grant_number":"754411"}],"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000664736300001"],"arxiv":["2102.04961"]},"oa":1,"file_date_updated":"2021-07-19T11:47:16Z","ec_funded":1,"article_number":"065009","date_updated":"2023-08-10T13:58:09Z","date_created":"2021-07-18T22:01:22Z","volume":23,"author":[{"full_name":"Huber, David","first_name":"David","last_name":"Huber"},{"first_name":"Oleksandr V.","last_name":"Marchukov","full_name":"Marchukov, Oleksandr V."},{"full_name":"Hammer, Hans Werner","first_name":"Hans Werner","last_name":"Hammer"},{"last_name":"Volosniev","first_name":"Artem","orcid":"0000-0003-0393-5525","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","full_name":"Volosniev, Artem"}],"publication_status":"published","department":[{"_id":"MiLe"}],"publisher":"IOP Publishing","acknowledgement":"We thank Aidan Tracy for his input during the initial stages of this project.

In this paper, we extend this approach to compute observables other than the energy. As an example, we calculate the densities, and phase fluctuations of one-dimensional Bose gases with one and two impurities. For a single mobile impurity, we use flow equations to validate the mean-field results obtained upon the Lee-Low-Pines transformation. We show that the mean-field approximation is accurate for all values of the boson-impurity interaction strength as long as the phase coherence length is much larger than the healing length of the condensate. For two static impurities, we calculate impurity-impurity interactions induced by the Bose gas. We find that leading order perturbation theory fails when boson-impurity interactions are stronger than boson-boson interactions. The mean-field approximation reproduces the flow equation results for all values of the boson-impurity interaction strength as long as boson-boson interactions are weak."}],"issue":"1","type":"journal_article","file":[{"date_updated":"2021-08-10T11:44:59Z","date_created":"2021-08-10T11:44:59Z","success":1,"checksum":"eaa847346b1a023d97bbb291779610ed","file_id":"9875","relation":"main_file","creator":"asandaue","file_size":1085300,"content_type":"application/pdf","file_name":"2021_SciPostPhysics_Brauneis.pdf","access_level":"open_access"}],"oa_version":"Published Version","title":"Impurities in a one-dimensional Bose gas: The flow equation approach","ddc":["530"],"status":"public","intvolume":" 11","_id":"9769","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","day":"13","article_processing_charge":"Yes","has_accepted_license":"1","scopus_import":"1","date_published":"2021-07-13T00:00:00Z","article_type":"original","publication":"SciPost Physics","citation":{"apa":"Brauneis, F., Hammer, H.-W., Lemeshko, M., & Volosniev, A.

Identifying systems where at least some eigenstates are nonthermal is an outstanding question. In this Letter we show that interacting quantum models that have a nullspace—a degenerate subspace of eigenstates at zero energy (zero modes), which corresponds to infinite temperature, provide a route to nonthermal eigenstates. We analytically show the existence of a zero mode which can be represented as a matrix product state for a certain class of local Hamiltonians. In the more general case we use a subspace disentangling algorithm to generate an orthogonal basis of zero modes characterized by increasing entanglement entropy. We show evidence for an area-law entanglement scaling of the least-entangled zero mode in the broad parameter regime, leading to a conjecture that all local Hamiltonians with the nullspace feature zero modes with area-law entanglement scaling and, as such, break the strong thermalization hypothesis. Finally, we find zero modes in constrained models and propose a setup for observing their experimental signatures."}],"type":"journal_article","file":[{"creator":"mserbyn","content_type":"application/pdf","file_size":5064231,"access_level":"open_access","file_name":"PhysRevLett.127.060602_SOM.pdf","success":1,"checksum":"51218f302dcef99d90d1209809fcc874","date_updated":"2021-08-13T09:28:08Z","date_created":"2021-08-13T09:28:08Z","file_id":"9904","relation":"main_file"}],"oa_version":"Published Version","intvolume":" 127","status":"public","title":"Area-law entangled eigenstates from nullspaces of local Hamiltonians","ddc":["539"],"_id":"9903","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"month":"08","language":[{"iso":"eng"}],"doi":"10.1103/physrevlett.127.060602","project":[{"name":"Non-Ergodic Quantum Matter: Universality, Dynamics and Control","call_identifier":"H2020","_id":"23841C26-32DE-11EA-91FC-C7463DDC885E","grant_number":"850899"}],"isi":1,"quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"external_id":{"isi":["000684276000002"],"arxiv":["2102.13633"]},"oa":1,"ec_funded":1,"file_date_updated":"2021-08-13T09:28:08Z","article_number":"060602","volume":127,"date_created":"2021-08-13T09:27:39Z","date_updated":"2023-08-11T10:43:27Z","author":[{"full_name":"Karle, Volker","id":"D7C012AE-D7ED-11E9-95E8-1EC5E5697425","orcid":"0000-0002-6963-0129","first_name":"Volker","last_name":"Karle"},{"full_name":"Serbyn, Maksym","last_name":"Serbyn","first_name":"Maksym","orcid":"0000-0002-2399-5827","id":"47809E7E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Michailidis, Alexios","orcid":"0000-0002-8443-1064","id":"36EBAD38-F248-11E8-B48F-1D18A9856A87","last_name":"Michailidis","first_name":"Alexios"}],"publisher":"American Physical Society","department":[{"_id":"MaSe"},{"_id":"GradSch"},{"_id":"MiLe"}],"publication_status":"published","acknowledgement":"We acknowledge useful discussions with V.

Here we show that gate-tuned van Hove singularities in rhombohedral trilayer graphene drive the spontaneous ferromagnetic polarization of the electron system into one or more spin- and valley flavors. Using capacitance measurements on graphite-gated van der Waals heterostructures, we find a cascade of density- and electronic displacement field tuned phase transitions marked by negative electronic compressibility. The transitions define the boundaries between phases where quantum oscillations have either four-fold, two-fold, or one-fold degeneracy, associated with a spin and valley degenerate normal metal, spin-polarized `half-metal', and spin and valley polarized `quarter metal', respectively. For electron doping, the salient features are well captured by a phenomenological Stoner model with a valley-anisotropic Hund's coupling, likely arising from interactions at the lattice scale. For hole filling, we observe a richer phase diagram featuring a delicate interplay of broken symmetries and transitions in the Fermi surface topology. Finally, by rotational alignment of a hexagonal boron nitride substrate to induce a moiré superlattice, we find that the superlattice perturbs the preexisting isospin order only weakly, leaving the basic phase diagram intact while catalyzing the formation of topologically nontrivial gapped states whenever itinerant half- or quarter metal states occur at half- or quarter superlattice band filling. Our results show that rhombohedral trilayer graphene is an ideal platform for well-controlled tests of many-body theory and reveal magnetism in moiré materials to be fundamentally itinerant in nature."}],"project":[{"grant_number":"754411","_id":"260C2330-B435-11E9-9278-68D0E5697425","name":"ISTplus - Postdoctoral Fellowships","call_identifier":"H2020"}],"quality_controlled":"1","isi":1,"external_id":{"isi":["000706977400002"],"arxiv":["2104.00653"]},"main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2104.00653"}],"oa":1,"language":[{"iso":"eng"}],"doi":"10.1038/s41586-021-03938-w","publication_identifier":{"issn":["0028-0836"],"eissn":["1476-4687"]},"month":"09","publisher":"Springer Nature","department":[{"_id":"MaSe"},{"_id":"MiLe"}],"publication_status":"published","acknowledgement":"The authors acknowledge discussions with A.

In this work, we propose a two-terminal cold-atom simulator to study that interaction. The proposed quantum simulator consists of strongly interacting atoms that occupy two temperature reservoirs connected by a one-dimensional link. First, we argue that the dynamics in the link can be described using an inhomogeneous Heisenberg spin chain whose couplings are defined by the local temperature. Second, we show the existence of a spin current in a system with a temperature difference by studying the dynamics that follows the spin-flip of an atom in the link. A temperature gradient accelerates the impurity in one direction more than in the other, leading to an overall spin current similar to the spin Seebeck effect."}]}]
