Nonperturbative Nonlinear Hall Effect in Nonequilibrium Steady States
Lei Geng, Martin Eckstein, Lei Chen +4
The nonlinear Hall effect in quantum materials has attracted broad interest, yet most existing studies focus on the weak-field, perturbative regime. Here we develop a nonperturbati…
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…
Measuring the ultrafast screening of in photo-excited charge-transfer insulators with time-resolved X-ray absorption spectroscopy
Denis Golez, Eva Paprotzki, Philipp Werner +1
Recent seminal experiments have utilized time-resolved X-ray absorption spectroscopy (XAS) to investigate the ultrafast photo-induced renormalization of the electron interaction ('…
Photo-induced charge-transfer renormalization in NiO
Tobias Lojewski, Denis Golez, Katharina Ollefs +21
Photo-doped states in strongly correlated charge transfer insulators are characterized by - and - interactions and the resulting intertwined dynamics of charge excitati…
