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…
Quantum simulation of spontaneous pair creation in 2D optical lattices
Leonhard Klar, Nikodem Szpak, Ralf Schützhold
One of the fundamental predictions of Quantum Electrodynamics (QED) is the spontaneous creation of particle--antiparticle pairs from vacuum in presence of a very strong electric fi…
Time reversal and quantum Loschmidt echo in optical lattices
Nikodem Szpak, Ralf Schützhold
A quantum Loschmidt echo (also referred to as quantum time mirror) corresponds to an effective time inversion after which the quantum wave function reverses its previous time evolu…
