Dynamical deconfinement transition driven by density of excitations
arXiv:2310.02320 · doi:10.1103/PhysRevB.111.024304
Abstract
We investigate the deconfinement transition driven by excitations in long-range spin models. At low temperatures, these models exhibit a confined phase where domain-wall (or kinks) are localized. As temperature increases, kinks interact and propagate, leading to a transition to a de-confined phase. This transition is influenced by the interplay between thermal energy and interaction effects, resulting in extended, de-confined regions. Although kinks density is dynamically stable, non-equilibrium changes in their fluctuations characterize the transition. Our findings provide insights into the mechanisms of confinement and deconfinement in long-range spin models, with implications for both condensed matter physics and lattice gauge theories. Bridging these fields, this study sheds light on the universal aspects of confinement and opens avenues for further exploration and experimental verification.
