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"}],"file_date_updated":"2022-03-14T08:38:49Z","department":[{"_id":"MiLe"}],"ddc":["530"],"date_updated":"2022-03-14T08:42:24Z","status":"public","type":"journal_article","article_type":"original","tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"_id":"10845"},{"department":[{"_id":"MiLe"}],"date_updated":"2023-08-02T14:30:22Z","status":"public","article_type":"review","type":"journal_article","_id":"10771","volume":34,"issue":"13","language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"eissn":["15214095"],"issn":["09359648"]},"intvolume":" 34","month":"04","main_file_link":[{"open_access":"1","url":"https://arxiv.org/abs/2108.09998"}],"scopus_import":"1","oa_version":"Preprint","abstract":[{"lang":"eng","text":"A critical overview of the theory of the chirality-induced spin selectivity (CISS) effect, that is, phenomena in which the chirality of molecular species imparts significant spin selectivity to various electron processes, is provided.

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","file_date_updated":"2022-07-18T06:33:13Z","department":[{"_id":"MiLe"}],"date_updated":"2023-08-03T11:57:41Z","ddc":["530"],"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","image":"/images/cc_by.png","name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","short":"CC BY (4.0)"},"article_type":"original","type":"journal_article","status":"public","_id":"11590"}]
