Non-linear sigma models for non-Hermitian random matrices in symmetry classes AI and AII
Anish Kulkarni, Kohei Kawabata, Shinsei Ryu
Symmetry of non-Hermitian matrices underpins many physical phenomena. In particular, chaotic open quantum systems exhibit universal bulk spectral correlations classified on the bas…

Dissipative Dynamics and Symmetry Breaking in Bosonic Sachdev-Ye-Kitaev Lindbladian
Yifei Liu, Anish Kulkarni, Shinsei Ryu
We investigate a bosonic variant of the Sachdev-Ye-Kitaev (SYK) model coupled to a Lindbladian environment, focusing on the interplay between quantum many-body dynamics and dissipa…
