Normal and superconducting currents through the Sachdev-Ye-Kitaev model

G Francica, M Uguccioni, L Dell'Anna - Physical Review B, 2023 - APS
We study the current driven by an applied voltage as a function of time through the Sachdev-
Ye-Kitaev model when coupled to two normal or superconducting reservoirs. For normal …

Generation and decay of Higgs mode in a strongly interacting Fermi gas

A Barresi, A Boulet, G Wlazłowski, P Magierski - Scientific Reports, 2023 - nature.com
We investigate the life cycle of the large amplitude Higgs mode in strongly interacting
superfluid Fermi gas. Through numerical simulations with time-dependent density functional …
