In open Fermi-Hubbard systems, two-particle interactions arise from any of the following: (1) presence of a particle of a different spin in the same site, (2) presence of a particle of different spin in a neighboring lattice site, or (3) the energy contributions from the bath. Using exact diagonalization, one can calculate for profiles of thermodynamic and demonstrate quantum heat engine and refrigerator processes and magnetoelectricity in the dimerized version. Similarly, through analytical methods, one can describe the temperature dependence of spin conductivity. Results differ for cases of repulsive and attractive two-particle interactions.
