Fermi-Hubbard gas with three-body losses: symmetries and dark states
Alice Marché, Alberto Nardin, Hosho Katsura +1
We study an invariant Fermi-Hubbard gas undergoing on-site three-body losses. The model presents eight independent strong symmetries preventing the complete deplet…

Universality and two-body losses: lessons from the effective non-Hermitian dynamics of two particles
Alice Marché, Hironobu Yoshida, Alberto Nardin +2
We study the late-time dynamics of two particles confined in one spatial dimension and subject to two-body losses. The dynamics is exactly described by a non-Hermitian Hamiltonian…
