We investigate the dynamic properties of systems at thermal first-order transitions (FOT), when boundary conditions favor one of the two phases. In particular, we study the dynamic scaling properties arising from a slow heating of systems with disordered boundary conditions, starting in the ordered phase and moving across the FOT. As a theoretical laboratory we consider the two-dimensional Potts model. We show that a power-law dynamic scaling emerges, associated with a mixed regime where the two phases are spatially separated. We argue that these features generally apply to systems at FOTs, when boundary conditions favor one of the two phases. In particular, they should be relevant for the experimental search of FOTs of the quark-gluon plasma in heavy-ion collisions.

Abstract

We investigate the dynamic properties of systems at thermal first-order transitions (FOT), when boundary conditions favor one of the two phases. In particular, we study the dynamic scaling properties arising from a slow heating of systems with disordered boundary conditions, starting in the ordered phase and moving across the FOT. As a theoretical laboratory we consider the two-dimensional Potts model. We show that a power-law dynamic scaling emerges, associated with a mixed regime where the two phases are spatially separated. We argue that these features generally apply to systems at FOTs, when boundary conditions favor one of the two phases. In particular, they should be relevant for the experimental search of FOTs of the quark-gluon plasma in heavy-ion collisions.
