Co-operating multiorbital and nonlocal correlations in bilayer nickelate
Evgeny A. Stepanov, Steffen Bötzel, Ilya M. Eremin +1
The interplay of multiorbital physics and nonlocal self-energy effects is studied within an effective three-orbital model for the high-pressure normal state of superconducting bila…

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…
