Electron Transfer in Donor-Acceptor Systems: Many-Particle Effects and Influence of Electronic Correlations
Sabine Tornow, Ning-Hua Tong, Ralf Bulla
We investigate electron transfer processes in donor-acceptor systems with a coupling of the electronic degrees of freedom to a common bosonic bath. The model allows to study many-p…

Numerical Renormalization Group for Bosonic Systems and Application to the Subohmic Spin-Boson Model
Ralf Bulla, Ning-Hua Tong, Matthias Vojta
We describe the generalization of Wilson's Numerical Renormalization Group method to quantum impurity models with a bosonic bath, providing a general non-perturbative approach to b…
