Numerical Renormalization Group for Quantum Impurities in a Bosonic Bath
Ralf Bulla, Hyun-Jung Lee, Ning-Hua Tong +1
We present a detailed description of the recently proposed numerical renormalization group method for models of quantum impurities coupled to a bosonic bath. Specifically, the meth…

Quantum Critical Points in Quantum Impurity Systems
H. -J. Lee, R. Bulla
The numerical renormalization group method is used to investigate zero temperature phase transitions in quantum impurity systems, in particular in the soft-gap Anderson model, wher…
