Our setup involves ferromagnetic couplings among the particles in different bands, leading to the development of strong spin-transport correlations in an intermediate interaction regime. Interactions are then strong enough to lift the degeneracy among singlet and triplet spin configurations in the well of the spin impurity but not strong enough to prohibit hole-induced magnetic excitations to the singlet state.

The typical formulation of the model is based upon a single particle picture, and should be extended when interactions with other particles become relevant. Here, we illustrate such an extension for a particle in an Aharonov-Bohm ring subject to interactions with a weakly interacting Bose gas. We show that the ground state of the system can be described using the Bose-polaron concept—a particle dressed by interactions with a bosonic environment. We connect the energy spectrum to the effective mass of the polaron, and demonstrate how to change currents in the system by tuning boson-particle interactions.

Comparison to alignment dynamics calculated from the time-dependent rotational Schrödinger equation shows that the deviation is due to the alignment dependent interaction between the dimer and the droplet surface. This interaction confines the dimer to the tangential plane of the droplet surface at the point where it resides and is the reason that the observed alignment dynamics is also well described by a 2D quantum rotor model.","lang":"eng"}],"oa_version":"Preprint","pmid":1,"scopus_import":"1","main_file_link":[{"open_access":"1","url":"https://doi.org/10.48550/arXiv.2308.15247"}],"month":"08","intvolume":" 131","publication_identifier":{"eissn":["1079-7114"],"issn":["0031-9007"]},"publication_status":"published","language":[{"iso":"eng"}],"issue":"5","volume":131,"ec_funded":1,"article_number":"053201","project":[{"_id":"2688CF98-B435-11E9-9278-68D0E5697425","call_identifier":"H2020","name":"Angulon: physics and applications of a new quasiparticle","grant_number":"801770"}],"citation":{"chicago":"Kranabetter, Lorenz, Henrik H.

In particular, such TQFTs are classified by fully dualisable objects together with a trivialisation of the rth power of their Serre automorphisms. For r=1, we recover the oriented case (on which our proof builds), while ordinary spin structures correspond to r=2.\r\nTo construct examples, we explicitly describe Spin 2r-homotopy fixed points in the equivariant completion of any symmetric monoidal 2-category.

An impurity causes a rapid variation of the scattering phase shift for fermions at the Fermi surface, introducing a new characteristic length scale into the problem. We investigate manifestations of this length scale in the self-energy of the impurity and in the density of the bath. Our calculations reveal a model-independent deformation of the density of the Fermi gas, which is determined by the width of the resonance. To provide a broader picture, we investigate time evolution of the density in quench dynamics, and study the behavior of the system at finite temperatures. Finally, we briefly discuss implications of our findings for the Fermi-polaron problem.","lang":"eng"}],"oa_version":"Published Version","author":[{"first_name":"Mikhail","id":"2E65BB0E-F248-11E8-B48F-1D18A9856A87","last_name":"Maslov","full_name":"Maslov, Mikhail","orcid":"0000-0003-4074-2570"},{"id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","first_name":"Mikhail","last_name":"Lemeshko","orcid":"0000-0002-6990-7802","full_name":"Lemeshko, Mikhail"},{"last_name":"Volosniev","full_name":"Volosniev, Artem","orcid":"0000-0003-0393-5525","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","first_name":"Artem"}],"external_id":{"arxiv":["2111.13570"]},"article_processing_charge":"No","title":"Impurity with a resonance in the vicinity of the Fermi energy","citation":{"apa":"Maslov, M., Lemeshko, M., & Volosniev, A.

First, we derive mean-field solutions to the problem on a finite ring for the two asymptotic cases: (i) all bosons are bound to the impurity and (ii) all bosons are in a scattering state. Moreover, we derive the critical line that separates these regimes in the parameter space. In the thermodynamic limit, this critical line determines the maximum number of bosons that can be bound by the impurity potential, forming an artificial atom. Second, we validate the mean-field results using the flow equation approach and the multi-layer multi-configuration time-dependent Hartree method for atomic mixtures. While beyond-mean-field effects destroy long-range order in the Bose gas, the critical boson number is unaffected. Our findings are important for understanding such artificial atoms in low-density Bose gases with static and mobile impurities.","lang":"eng"}],"oa_version":"Published Version","author":[{"full_name":"Brauneis, Fabian","last_name":"Brauneis","first_name":"Fabian"},{"full_name":"Backert, Timothy G.","last_name":"Backert","first_name":"Timothy G."},{"last_name":"Mistakidis","full_name":"Mistakidis, Simeon I.","first_name":"Simeon I."},{"first_name":"Mikhail","id":"37CB05FA-F248-11E8-B48F-1D18A9856A87","last_name":"Lemeshko","orcid":"0000-0002-6990-7802","full_name":"Lemeshko, Mikhail"},{"first_name":"Hans Werner","last_name":"Hammer","full_name":"Hammer, Hans Werner"},{"first_name":"Artem","id":"37D278BC-F248-11E8-B48F-1D18A9856A87","last_name":"Volosniev","full_name":"Volosniev, Artem","orcid":"0000-0003-0393-5525"}],"article_processing_charge":"No","external_id":{"isi":["000818530000001"]},"title":"Artificial atoms from cold bosons in one dimension","citation":{"ista":"Brauneis F, Backert TG, Mistakidis SI, Lemeshko M, Hammer HW, Volosniev A. 2022.
