Nonlocal Correlation Effects in dc and Optical Conductivity of the Hubbard Model
Nagamalleswararao Dasari, Hugo U. R. Strand, Martin Eckstein +2
Conductivity is one of the most direct probes of electronic systems, yet its theoretical description remains challenging in the presence of strong non-local correlations. In this L…
Electron-magnon dynamics triggered by an ultrashort laser pulse: A real-time Dual study
Nagamalleswararao Dasari, Hugo U. R. Strand, Martin Eckstein +2
Ultrafast irradiation of correlated electronic systems triggers complex dynamics involving quasi-particle excitations, doublons, charge carriers, and spin fluctuations. To describe…
Dynamically induced doublon repulsion in the Fermi-Hubbard model probed by a single-particle density of states
V. N. Valmispild, C. Dutreix, M. Eckstein +3
We investigate the possibility to control dynamically the interactions between repulsively bound pairs of fermions (doublons) in correlated systems with off-resonant ac fields. We…
Optical control of competing exchange interactions and coherent spin-charge coupling in two-orbital Mott insulators
M. M. S. Barbeau, M. Eckstein, M. I. Katsnelson +1
In order to have a better understanding of ultrafast electrical control of exchange interactions in multi-orbital systems, we study a two-orbital Hubbard model at half filling unde…
Ultrafast Quenching of the Exchange Interaction in a Mott Insulator
J. H. Mentink, M. Eckstein
We investigate how fast and how effective photocarrier excitation can modify the exchange interaction in the prototype Mott-Hubbard insulator. We demonstrate an ult…
