Relationship between Population Dynamics and the Self-Energy in Driven Non-Equilibrium Systems
We compare the decay rates of excited populations directly calculated within a Keldysh formalism to the equation of motion of the population itself for a Hubbard-Holstein model in two dimensions. While it is true that these two approaches must give the same answer, it is common to make a number of s...
