Infinite-temperature thermostats by energy localization in a nonequilibrium setup
Michele Giusfredi, Stefano Iubini, Antonio Politi +1
Some lattice models having two conservation laws may display an equilibrium phase transition from a homogeneous (positive temperature - PT) to a condensed (negative temperature) ph…
