Halimeh author MaSe department IST-BRIDGE: International postdoctoral program project 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 also can lend itself to upcoming experiments. Here we show how confinement in a Z2 LGT can be 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 Z2 LGTs and can be tested on current and near-term quantum devices. https://research-explorer.ista.ac.at/download/20327/20333/2025_PhysReviewB_Desaules.pdf application/pdfno American Physical Society2025 eng 2469-9950 2469-9969 2404.11645 00153046550000710.1103/mfg2-t6gb 1121 https://research-explorer.ista.ac.at/record/19791 Desaules, Jean-Yves Marc, et al. “Mass-Assisted Local Deconfinement in a Confined Z2 Lattice Gauge Theory.” <i>Physical Review B</i>, vol. 112, no. 1, 014301, American Physical Society, 2025, doi:<a href="https://doi.org/10.1103/mfg2-t6gb">10.1103/mfg2-t6gb</a>.
