Journal ArticleDOI
Experimental characterization of a quantum many-body system via higher-order correlations

TL;DR: This work studies a pair of tunnel-coupled one-dimensional atomic superfluids and characterize the corresponding quantum many-body problem by measuring correlation functions and concludes that in thermal equilibrium this system can be seen as a quantum simulator of the sine-Gordon model, relevant for diverse disciplines ranging from particle physics to condensed matter.
Journal ArticleDOI
Quantum quench of the Sachdev-Ye-Kitaev model
TL;DR: In this paper, the authors describe the nonequilibrium quench dynamics of the Sachdev-Ye-Kitaev models of fermions with random all-to-all interactions and provide tractable models of the dynamics of quantum systems without quasiparticle excitations.
Journal ArticleDOI
Schwinger pair production with ultracold atoms
TL;DR: In this article, the authors consider a system of ultracold atoms in an optical lattice as a quantum simulator for electron-positron pair production in quantum electrodynamics.
Journal ArticleDOI
Fermion production from real-time lattice gauge theory in the classical-statistical regime
TL;DR: In this article, the real-time dynamics of U(1) and SU(N) gauge theories coupled to fermions on a lattice were investigated, and a nonperturbative simulation method was applied to electron-positron production in quantum electrodynamics in three spatial dimensions.
Journal ArticleDOI
Implementing quantum electrodynamics with ultracold atomic systems
Valentin Kasper,Valentin Kasper,Florian Hebenstreit,Fred Jendrzejewski,Markus K. Oberthaler,Juergen Berges +5 more
TL;DR: In this article, the experimental engineering of model systems for the description of quantum electrodynamics (QED) in one spatial dimension via a mixture of bosonic 23Na and fermionic 6Li atoms is discussed.
