Role of exceptional points in the dynamics of the Lindblad Sachdev-Ye-Kitaev model
Jie-ping Zheng, Jorge Dukelsky, Rafael A. Molina +1
The out of equilibrium dynamics of the Sachdev-Ye-Kitaev model (SYK), comprising Majoranas with random all-to-all four-body interactions, minimally coupled to a Markovian bath…
