Exact Liouvillian spectrum of a one-dimensional dissipative Hubbard model

I will present exact results on a one-dimensional dissipative Fermi-Hubbard model subject to two-body loss, which is relevant to recent cold-atom experiments [1]. Here, the integrability of a non-Hermitian Hubbard model with complex-valued interaction strength and the triangular structure of the Liouvillian play an essential role. If time permits, I will also talk about exact results on other solvable models in open quantum many-body systems [2,3].
