High-temperature -pairing superconductivity in the photodoped Hubbard model
Lei Geng, Aaram J. Kim, Philipp Werner
We investigate superconductivity emerging in the photodoped Mott insulating Hubbard model using steady-state dynamical mean-field theory implemented on the real-frequency axis. By…

Photoinduced excitonic magnetism in a multiorbital Hubbard system
Lei Geng, Sujay Ray, Philipp Werner
Multiorbital Hubbard models with Hund coupling and crystal-field splitting exhibit an instability toward spin-triplet excitonic order in the parameter regime characterized by stron…

Hidden Kondo lattice physics in single-orbital Hubbard models
Philipp Werner, Sayed Ali Akbar Ghorashi
Single-orbital Hubbard models exhibit remarkably nontrivial correlation phenomena, even on nonfrustrated bipartite lattices. Some of these, like non-Fermi-liquid metal states, or t…
