Query: Environment-induced decay dynamics of anti-ferromagnetic order in
  Mott-Hubbard systems   We study the dissipative Fermi-Hubbard model in the limit of weak tunneling
and strong repulsive interactions, where each lattice site is tunnel-coupled to
a Markovian fermionic bath. For cold baths at intermediate chemical potentials,
the Mott insulator property remains stable and we find a fast relaxation of the
particle number towards half filling. On longer time scales, we find that the
anti-ferromagnetic order of the Mott-N\'eel ground state on bi-partite lattices
decays, even at zero temperature. For zero and non-zero temperatures, we
quantify the different relaxation time scales by means of waiting time
distributions which can be derived from an effective (non-Hermitian)
Hamiltonian and obtain fully analytic expressions for the Fermi-Hubbard model
on a tetramer ring.
