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…
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…
Heisenberg-exchange-free nanoskyrmion mosaic
E. A. Stepanov, S. A. Nikolaev, C. Dutreix +2
Isotropic Heisenberg exchange naturally appears as the main interaction in magnetism, usually favouring long-range spin-ordered phases. The anisotropic Dzyaloshinskii-Moriya intera…
Dynamical and Reversible Control of Topological Spin Textures
E. A. Stepanov, C. Dutreix, M. I. Katsnelson
Recent observations of topological spin textures brought spintronics one step closer to new magnetic memories. Nevertheless, the existence of Skyrmions, as well as their stabilizat…
