Description
We study a non-equilibrium behavior of an impurity connected to the SYK bath. From the Kadanoff-Baym equations for a noninteracting impurity, we see that the only relevant property for the impurity occupation is a combination of hybridisation and density of states of the bath. These parameters can be adjusted in order to model the impurity connected to any bath of interest. Using this approach, we can study the impurity dynamics connected to an SYK bath by making suitable changes to the hybridisation in an impurity plus Fermi bath setting in the thermodynamic limit.
