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.

TL;DR: The results establish universal scaling dynamics in an isolated quantum many-body system, which is a crucial step towards characterizing time evolution far from equilibrium in terms of universality classes.

TL;DR: A scalable analog quantum simulator of a U(1) gauge theory in one spatial dimension is proposed using interspecies spin-changing collisions in an atomic mixture to achieve gauge-invariant interactions between matter and gauge fields with spin- and species-independent trapping potentials.

TL;DR: In this paper, Baier et al. studied the nonequilibrium evolution of heavy-ion collisions in the limit of weak coupling at very high energy employing lattice simulations of the classical Yang-Mills equations and found that the dynamics of the longitudinally expanding plasma becomes independent of the details of the initial conditions.

TL;DR: In this article, the scaling properties of a quantum many-body system were investigated using a spinor Bose-Einstein condensate, and it was shown that the dynamics are governed by an emergent conserved quantity and the transport of spin excitations towards low momentum scales.
