Quantum impurity models coupled to Markovian and non-Markovian baths
Quantum impurity models coupled to Markovian and non-Markovian baths
We develop a method to study quantum impurity models, small interacting quantum systems bilinearly coupled to an environment, in the presence of an additional Markovian quantum bath, with a generic nonlinear coupling to the impurity. We aim at computing the evolution operator of the reduced density matrix of the impurity, …
