Quantum radiation in dielectric media with dispersion and dissipation
Sascha Lang, Ralf Schützhold, William G. Unruh
By a generalization of the Hopfield model, we construct a microscopic Lagrangian describing a dielectric medium with dispersion and dissipation. This facilitates a well-defined and…
Relaxation dynamics in a Hubbard dimer coupled to fermionic baths: phenomenological description and its microscopic foundation
Eric Kleinherbers, Nikodem Szpak, Jürgen König +1
We study relaxation dynamics in a strongly-interacting two-site Fermi-Hubbard model that is induced by coupling each site to a local fermionic bath. To derive the proper form of th…
Hierarchy of double-time correlations
Friedemann Queisser, Ralf Schützhold
The hierarchy of correlations is an analytical approximation method which allows us to study non-equilibrium phenomena in strongly interacting quantum many-body systems on lattices…
Boltzmann relaxation dynamics of strongly interacting spinless fermions on a lattice
Friedemann Queisser, Sebastian Schreiber, Peter Kratzer +1
Motivated by the recent interest in non-equilibrium phenomena in quantum many-body systems, we study strongly interacting fermions on a lattice by deriving and numerically solving…
Particle pair creation by inflation of quantum vacuum fluctuations in an ion trap
Matthias Wittemer, Frederick Hakelberg, Philip Kiefer +5
The creation of matter and structure in our universe is currently described by an intricate interplay of quantum field theory and general relativity. Signatures of this process dur…
