Theoretical model for multi-orbital Kondo screening in strongly correlated molecules with several unpaired electrons
Aitor Calvo-Fernández, Manish Kumar, Diego Soler-Polo +3
The mechanism of Kondo screening in strongly correlated molecules with several unpaired electrons on a metal surface is still under debate. Here, we provide a theoretical framework…

The PointGroupNRG code for numerical renormalization group calculations with discrete point-group symmetries
Aitor Calvo-Fernández, MarÃa Blanco-Rey, Asier Eiguren
The numerical renormalization group (NRG) has been widely used as a magnetic impurity solver since the pioneering works by Wilson. Over the past decades, a significant attention ha…

Numerical renormalization group calculations for magnetic impurity systems with spin-orbit coupling and crystal-field effects
Aitor Calvo-Fernández, MarÃa Blanco-Rey, Asier Eiguren
Exploiting symmetries in the numerical renormalization group (NRG) method significantly enhances performance by improving accuracy, increasing computational speed, and optimizing m…
