However, so far, most of the work on these systems has concentrated on zero-temperature phases while the corresponding finite-temperature regime remains largely unexplored. The question if and up to which temperature characteristic features of the zero-temperature phases persist is relevant in experimental realizations. We investigate a two-leg ladder lattice in a uniform magnetic field and concentrate our study on chiral edge currents and momentum-distribution functions, which are key observables in ultracold quantum-gas experiments. These quantities are computed for hard-core bosons as well as noninteracting bosons and spinless fermions at zero and finite temperatures. We employ a matrix-product-state based purification approach for the simulation of strongly interacting bosons at finite temperatures and analyze finite-size effects. Our main results concern the vortex-fluid-to-Meissner crossover of strongly interacting bosons. We demonstrate that signatures of the vortex-fluid phase can still be detected at elevated temperatures from characteristic finite-momentum maxima in the momentum-distribution functions, while the vortex-fluid phase leaves weaker fingerprints in the local rung currents and the chiral edge current. In order to determine the range of temperatures over which these signatures can be observed, we introduce a suitable measure for the contrast of these maxima. The results are condensed into a finite-temperature crossover diagram for hard-core bosons."],["dc.identifier.arxiv","1901.07083v3"],["dc.identifier.doi","10.1103/PhysRevA.99.053601"],["dc.identifier.eissn","2469-9934"],["dc.identifier.issn","2469-9926"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/75533"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.relation.issn","2469-9926"],["dc.relation.issn","2469-9934"],["dc.title","Finite-temperature properties of interacting bosons on a two-leg flux ladder"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

Most studies were carried out for Hamiltonians relevant for ultracold quantum gases and single-component systems of spins, fermions, or bosons. The paradigmatic example for thermalization in solid-state physics are phonons serving as a bath for electrons. This situation is often viewed from an open-quantum system perspective. Here, we ask whether a minimal microscopic model for electron-phonon coupling is quantum chaotic and whether it obeys ETH, if viewed as a closed quantum system. Using exact diagonalization, we address this question in the framework of the Holstein polaron model. Even though the model describes only a single itinerant electron, whose coupling to dispersionless phonons is the only integrability-breaking term, we find that the spectral statistics and the structure of Hamiltonian eigenstates exhibit essential properties of the corresponding random-matrix ensemble. Moreover, we verify the ETH ansatz both for diagonal and offdiagonal matrix elements of typical phonon and electron observables, and show that the ratio of their variances equals the value predicted from random-matrix theory."],["dc.identifier.doi","10.1103/PhysRevB.99.155130"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/16119"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/90941"],["dc.identifier.url","https://publications.goettingen-research-online.de/handle/2/62297"],["dc.language.iso","en"],["dc.relation","SFB 1073: Kontrolle von Energiewandlung auf atomaren Skalen"],["dc.relation","SFB 1073 | Topical Area B | B09 Transporteigenschaften von elektronen-phononengekoppelten Systemen"],["dc.relation.issn","2469-9950"],["dc.relation.issn","2469-9969"],["dc.rights","CC BY 4.0"],["dc.title","Eigenstate thermalization and quantum chaos in the Holstein polaron model"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.subtype","original_ja"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]
