Optimized auxiliary representation of non-Markovian impurity problems by a Lindblad equation

We present a general scheme to address correlated nonequilibrium quantum impurity problems based on a mapping onto an auxiliary open quantum system of small size. The infinite fermionic reservoirs of the original system are thereby replaced by a small number N _B of noninteracting auxiliary bath sit...
