Unconventional pairing in few-fermion systems at finite temperature
Daniel Pęcak, Tomasz Sowiński
Attractively interacting two-component mixtures of fermionic particles confined in a one-dimensional harmonic trap are investigated. Properties of balanced and imbalanced systems a…
Fundamental limitations of the eigenvalue continuation approach
Tomasz Sowiński, Miguel A. Garcia-March
In this work, we show that the eigenvalue continuation approach introduced recently in [Phys. Rev. Lett. {\bf 121}, 032501 (2018)], despite its many advantages, has some fundamenta…
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…
Few strongly interacting fermions of different mass driven in the vicinity of a critical point
Damian Włodzyński, Tomasz Sowiński
It was recently argued that one-dimensional systems of several strongly interacting fermions of different mass undergo critical transitions between different spatial orderings when…
