Title: Mass-Assisted Local Deconfinement in a Confined $\mathbb{Z}_2$ Lattice Gauge Theory
Authors: Jean-Yves Desaules, Thomas Iadecola, Jad C. Halimeh,
Abstract summary: We show how confinement in a $mathbbZ$ LGT can be textitlocally avoided by proximity to a resonance between the fermion mass and the electric field strength. Our findings provide deeper insights into the nature of confinement in $mathbbZ$ LGTs and can be tested on current and near-term quantum devices.

Abstract: Confinement is a prominent phenomenon in condensed matter and high-energy physics that has recently become the focus of quantum-simulation experiments of lattice gauge theories (LGTs). As such, a theoretical understanding of the effect of confinement on LGT dynamics is not only of fundamental importance, but can lend itself to upcoming experiments. Here, we show how confinement in a $\mathbb{Z}_2$ LGT can be \textit{locally} avoided by proximity to a resonance between the fermion mass and the electric field strength. Furthermore, we show that this local deconfinement can become global for certain initial conditions, where information transport occurs over the entire chain. In addition, we show how this can lead to strong quantum many-body scarring starting in different initial states. Our findings provide deeper insights into the nature of confinement in $\mathbb{Z}_2$ LGTs and can be tested on current and near-term quantum devices.

Quantum simulation of lattice gauge theories (LGTs) aims at tackling non-perturbative particle and condensed matter physics. One of the current challenges is to go beyond 1+1 dimensions, where four-body (plaquette) interactions, not contained naturally in quantum simulating devices, appear.

Zitterbewegung and Klein-tunneling phenomena for transient quantum waves [77.34726150561087]
We show that the Zitterbewegung effect manifests itself as a series of quantum beats of the particle density in the long-time limit. We also find a time-domain where the particle density of the point source is governed by the propagation of a main wavefront. The relative positions of these wavefronts are used to investigate the time-delay of quantum waves in the Klein-tunneling regime.
