Stability and complexity of global iterative solvers for the Kadanoff-Baym equations
Jože Gašperlin, Denis Golež, Jason Kaye
Although the Kadanoff-Baym equations are typically solved using time-stepping methods, iterative global-in-time solvers offer potential algorithmic advantages, particularly when co…
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…
Doublon-Holon Pairing State in Photodoped Mott Insulators
Ryota Ueda, Madhumita Sarkar, Zala LenarÄiÄ +3
We demonstrate the existence of an unconventional pairing state in photodoped Mott insulators on ladder and quasi-two-dimensional geometries, characterized by quasi-long-range doub…
2D coherent spectroscopy signatures of exciton condensation in TaNiSe
Jiyu Chen, Jernej Mravlje, Denis Golež +1
We show that the nonlinear optical response probed by two-dimensional coherent spectroscopy (2DCS) can discriminate between excitonic and lattice driven order. In the excitonic reg…
Driving collective current excitations using light: The two-time approach
Chin Shen Ong, Denis Golež, Angel Rubio +2
We identify a distinct transverse collective excitation, which we name the "curron", arising from current-current interactions in a driven quantum metal. Unlike plasmons, which inv…
