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…
Photoemission Signatures of Photoinduced Carriers and Excitons in One-Dimensional Mott Insulators
Taiga Nakamoto, Yuta Murakami, Naoto Tsuji
We theoretically study photoemission spectra for photodoped one-dimensional Mott insulators that can host excitons, and show that their spectral characteristics differ qualitativel…
Excitonic correlations in the equilibrium and voltage-biased bilayer Hubbard model: multi-orbital two-particle self-consistent approach
Jiawei Yan, Jonas B. Profe, Yuta Murakami +1
We develop a nonequilibrium multi-orbital extension of the two-particle self-consistent theory and apply it to the bilayer Hubbard model as a minimal platform to investigate correl…
Charge creation via quantum tunneling in one-dimensional Mott insulators: A numerical study of the extended Hubbard model
Thomas Hansen, Lars Bojer Madsen, Yuta Murakami
Charge creation via quantum tunneling, i.e. dielectric breakdown, is one of the most fundamental and significant phenomena arising from strong light(field)-matter coupling. In this…
