Abstract: | When a system of correlated electrons is embedded in a dissipative environment, new emergent phenomena might occur due to
the interplay of correlation and dissipation. Here we focus on quantum impurity systems with coupling to a bosonic bath. For
the theoretical investigation we introduce the bosonic numerical renormalization group method which has been initially set
up for the spin-boson model. The role of both correlations and dissipation is described in the context of two-electron transfer
systems. We also discuss prospects for the investigation of lattice models of correlated electrons with coupling to a dissipative
bath. |
