Dynamical deconfinement transition driven by density of excitations
Nishan Ranabhat, Alessandro Santini, Emanuele Tirrito +1
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)…
