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…
NESSi 2.0: The Non-Equilibrium Systems Simulation package version 2.0
Fabian Künzel, Michael Schüler, Denis Golež +7
Nonequilibrium Green's functions provide a powerful framework for studying quantum many-body dynamics including the laser-induced dynamics in solids. The Non-Equilibrium Systems Si…
Ultrafast Electronic Structure Engineering in 1-TaS: Role of Doping and Amplitude Mode Dynamics
J. Jayabalan, Jiyu Chen, Laura Pätzold +12
In strongly correlated transition metal dichalcogenides, an intricate interplay of polaronic distortions, stacking arrangement, and electronic correlations determines the nature of…
The 2025 Roadmap to Ultrafast Dynamics: Frontiers of Theoretical and Computational Modelling
Fabio Caruso, Michael A. Sentef, Claudio Attaccalite +27
The exploration of ultrafast phenomena is a frontier of condensed matter research, where the interplay of theory, computation, and experiment is unveiling new opportunities for und…
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…
Multidimensional coherent spectroscopy of correlated lattice systems
Jiyu Chen, Philipp Werner
Multidimensional coherent spectroscopy (MDCS) has been established in quantum chemistry as a powerful tool for studying the nonlinear response and nonequilibrium dynamics of molecu…
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 nonequilibrium states in Mott insulators
Yuta Murakami, Denis Golež, Martin Eckstein +1
The study of nonequilibrium phenomena in interacting lattice systems can provide new perspectives on correlation effects, and information on metastable states of matter. Mott insul…
Nonequilibrium DMFT approach to time-resolved Raman spectroscopy
Philipp Werner, Martin Eckstein, Naoto Tsuji
Raman spectroscopy uses light scattering to extract information on low-energy excitations of solids. The Raman process is described by diagrams which are fourth order in the light-…
Ultrafast doublon dynamics in photo-excited 1T-TaS
Manuel Ligges, Isabella Avigo, Denis Golež +8
Strongly correlated systems exhibit intriguing properties caused by intertwined microscopic in- teractions that are hard to disentangle in equilibrium. Employing non-equilibrium ti…
