The light-matter correlation energy functional of the cavity-coupled two-dimensional electron gas via quantum Monte Carlo simulations
Lukas Weber, Miguel A. Morales, Johannes Flick +2
We perform extensive simulations of the two-dimensional cavity-coupled electron gas in a modulating potential as a minimal model for cavity quantum materials. These simulations are…

Phaseless auxiliary-field quantum Monte Carlo method for cavity-QED matter systems
Lukas Weber, Leonardo dos Anjos Cunha, Miguel A. Morales +2
We present a generalization of the phaseless auxiliary-field quantum Monte Carlo (AFQMC) method to cavity quantum-electrodynamical (QED) matter systems. The method can be formulate…

Dynamical quasi-condensation in the weakly interacting Fermi-Hubbard model
Iva Březinová, Markus Stimpfle, Stefan Donsa +1
We study dynamical (quasi)-condensation in the Fermi-Hubbard model starting from a completely uncorrelated initial state of adjacent doubly occupied sites. We show that upon expans…
