Interacting hydrodynamic modes in spinless fermions with dephasing noise
Fabian H. L. Essler, Patrik Penc
We study the non-equilibrium dynamics of spinless fermions with dephasing noise in the framework of a many-particle Lindblad equation. Using a mapping to the exactly solvable one-d…

Linear response and exact hydrodynamic projections in Lindblad equations with decoupled Bogoliubov hierarchies
Patrik Penc, Fabian H. L. Essler
We consider a class of spinless-fermion Lindblad equations that exhibit decoupled BBGKY hierarchies. In the cases where particle number is conserved, their late time behaviour is c…

Loss-induced quantum information jet in an infinite temperature Hubbard chain
Patrik Penc, Cătălin Paşcu Moca, Örs Legeza +3
Information propagation in the one-dimensional infinite temperature Hubbard model with a dissipative particle sink at the end of a semi-infinite chain is studied. In the strongly i…
