Tunable Hilbert space fragmentation and extended critical regime
Mateusz Lisiecki, Janez Bonča, Marcin Mierzejewski +2
Systems exhibiting the Hilbert-space fragmentation are nonergodic, and their Hamiltonians decompose into exponentially many blocks in the computational basis. In many cases, these…
Fading ergodicity meets maximal chaos
Rafał Świętek, Patrycja Łydżba, Lev Vidmar
Fading ergodicity provides a theoretical framework for understanding deviations from the eigenstate thermalization hypothesis (ETH) near ergodicity-breaking transitions. In this wo…
Localization transitions in quadratic systems without quantum chaos
Mateusz Lisiecki, Lev Vidmar, Patrycja Łydżba
Transitions from delocalized to localized eigenstates have been extensively studied in both quadratic and interacting models. The delocalized regime typically exhibits diffusion an…
Signatures of quantum chaos in low-energy mixtures of few fermions
Patrycja Łydżba, Tomasz Sowiński
The low energy dynamics of mesoscopic systems strongly depends on the presence of internal equilibration. For this reason, a better interpretation of ultracold atom experiments req…
Unconventional pairing in one-dimensional systems of a few mass-imbalanced ultracold fermions
Patrycja Łydżba, Tomasz Sowiński
We study the ground-state properties of a two-component fermionic mixture effectively confined in a one-dimensional harmonic trap. We consider scenarios when numbers of particles i…
