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…

Role of phonon coupling in driving photo-excited Mott insulators towards a transient superconducting steady state
Sujay Ray, Martin Eckstein, Philipp Werner
Understanding light-induced hidden orders is relevant for nonequilibrium materials control and future ultrafast technologies. Hidden superconducting order, in particular, has been…
