Linear-response theory in Floquet systems
Ayan Pal, Erik G. C. P. van Loon, Ferdi Aryasetiawan
Nonequilibrium quantum physics greatly simplifies in the case of time-periodic Hamiltonians, since Floquet theory provides an analogue to Bloch's theorem in the time domain. Still,…
Downfolding the Su-Schrieffer-Heeger model
Arne Schobert, Jan Berges, Tim Wehling +1
Charge-density waves are responsible for symmetry-breaking displacements of atoms and concomitant changes in the electronic structure. Linear response theories, in particular densi…
The Bethe-Salpeter equation at the critical end-point of the Mott transition
Erik G. C. P. van Loon, Friedrich Krien, Andrey A. Katanin
Strong repulsive interactions between electrons can lead to a Mott metal-insulator transition. The Dynamical Mean-Field Theory (DMFT) explains the critical end-point and hysteresis…
Thermodynamics of the metal-insulator transition in the extended Hubbard model
M. Schüler, E. G. C. P. van Loon, M. I. Katsnelson +1
In contrast to the Hubbard model, the extended Hubbard model, which additionally accounts for non-local interactions, lacks systemic studies of thermodynamic properties especially…
Dual Boson approach with instantaneous interaction
L. Peters, E. G. C. P. van Loon, A. N. Rubtsov +3
The Dual Boson approach to strongly correlated systems generally involves a dynamic (frequency-dependent) interaction in the auxiliary impurity model. In this work, we explore the…
Fermion-boson vertex within Dynamical Mean-Field Theory
Erik G. C. P. van Loon, Friedrich Krien, Hartmut Hafermann +2
In the study of strongly interacting systems, correlations on the two-particle level are receiving more and more attention. In this work, we study a particular two-particle correla…
