Magnetism Induced by Periodically Driven Non-Magnetic Impurities on Surfaces with Spin-Orbit Coupling
Malen Etxeberria-Etxaniz, Andrés Arnau, Asier Eiguren
We investigate the response of the Rashba spin-orbit system to a time-periodic scalar potential, in order to determine whether an induced magnetization exists. We approach this by…
Numerical renormalization group calculations for magnetic impurity systems with spin-orbit coupling and crystal-field effects
Aitor Calvo-Fernández, María 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…
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…
Multi-orbital Kondo screening in strongly correlated polyradical nanographenes
Aitor Calvo-Fernández, Diego Soler-Polo, Andrés Pinar Solé +9
We discuss coexistence of Kondo and spin excitation signals in tunneling spectroscopy in strongly correlated polyradical -magnetic nanographenes on a metal surface. The Kondo si…
The PointGroupNRG code for numerical renormalization group calculations with discrete point-group symmetries
Aitor Calvo-Fernández, María 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…
Microscopic theory of spin-relaxation of a single Fe adatom coupled to substrate vibrations
Haritz Garai-Marin, Manuel dos Santos Dias, Samir Lounis +2
Understanding the spin-relaxation mechanism of single adatoms is an essential step towards creating atomic magnetic memory bits or even qubits. Here we present an essentially param…
