Non-equilibrium dissipative stabilization of s- and d-wave superconductivity
Aleksey Lunkin, Yury Holubeu, Denis Golež +1
Stabilizing superconductivity beyond its equilibrium regime has been one of the quests of nonequilibrium state engineering. We report the presence of nonthermal pairing gap in BCS…
H-NESSi: The Hierarchical Non-Equilibrium Systems Simulation package
Thomas Blommel, Jeremija Kovačević, Jason Kaye +3
We present H-NESSi (The Hierarchical Non-Equilibrium Systems Simulation package), an open-source software package for solving the Kadanoff-Baym equations (KBE) of nonequilibrium Gr…
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…
Automated evaluation of imaginary time strong coupling diagrams by sum-of-exponentials hybridization fitting
Zhen Huang, Denis Golež, Hugo U. R. Strand +1
We present an efficient separation of variables algorithm for the evaluation of imaginary time Feynman diagrams appearing in the bold pseudo-particle strong coupling expansion of t…
Optical signatures of dynamical excitonic condensates
Alexander Osterkorn, Yuta Murakami, Tatsuya Kaneko +3
We theoretically study dynamical excitonic condensates occurring in bilayers with an imposed chemical potential difference and in photodoped semiconductors. We show that optical sp…
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 ('…
