Abstract

The quantum simulation of gauge theories on synthetic quantum matter devices has gained a lot of traction in the last decade, making possible the observation of a range of exotic quantum many-body phenomena. In this work, we consider the spin-$1/2$ quantum link formulation of $1+1$D quantum electrodynamics with a topological $theta$-angle, which can be used to tune a confinement-deconfinement transition. Exactly mapping this system onto a PXP model with mass and staggered magnetization terms, we show an intriguing interplay between confinement and the ergodicity-breaking paradigms of quantum many-body scarring and Hilbert-space fragmentation. We map out the rich dynamical phase diagram of this model, finding an ergodic phase at small values of the mass $mu$ and confining potential $chi$, an emergent integrable phase for large $mu$, and a fragmented phase for large values of both parameters. We also show that the latter hosts resonances that lead to a vast array of effective models. We propose experimental probes of our findings, which can be directly accessed in current cold-atom setups.

Gauge theories provide a fundamental description of elementary particles. The understanding of non-equilibrium properties of gauge theories promises to shed light on a variety of dynamical phenomena across high-energy particle physics, condensed matter and even the evolution of the early universe. In parallel with the traditional methods used to study gauge theories, such as high-energy particle colliders, analog simulation using synthetic quantum matter has recently emerged as a powerful alternative for probing the dynamics of such theories on a lattice.

In our work, we numerically study a spin-1/2 regularization of the Schwinger model which describes 1+1D quantum electrodynamics. We show that varying the model parameters – the fermionic mass and the topological angle – allows one to access a wide range of dynamical phenomena. In particular, we find regimes where quantum dynamics results in persistent oscillations from special initial states, which are identified with quantum many-body scarring. Surprisingly, we find that the scarred oscillations can be enhanced in the presence of confinement. In other parts of parameter space, the Hilbert space fractures into exponentially many components, with an additional structure appearing in the form of two-parameter resonances. Finally, through large-scale numerical simulations, we show that our findings can be realized in the existing experiments on ultracold bosons in optical lattices
