Open Wilson chains for quantum impurity models: Keeping track of all bath modes
Benedikt Bruognolo, Nils-Oliver Linden, Frauke Schwarz +6
When constructing a Wilson chain to represent a quantum impurity model, the effects of truncated bath modes are neglected. We show that their influence can be kept track of systema…

Interleaved numerical renormalization group as an efficient multiband impurity solver
K. M. Stadler, A. K. Mitchell, J. von Delft +1
Quantum impurity problems can be solved using the numerical renormalization group (NRG), which involves discretizing the free conduction electron system and mapping to a `Wilson ch…
