Momentum-resolved Floquet-engineered pair and single-particle filter in the Fermi-Hubbard model

Year: 2023

Type: article

Abstract: We investigate the transport properties of a Fermi-Hubbard chain with an impurity which is formed by a site with a periodically modulated chemical potential. We determine the momentum-resolved transmission through this impurity in dependence of the modulation frequency and strength for a single particle and a pair of fermions. We find that the pair transmission has a very distinct behavior from the single-particle transmission. Different situations can occur, where only the single particle or the pair with a certain momentum is transmitted or filtered out.
