Comment on "Freezing by heating in a driven mesoscopic system"
Leo Radzihovsky, Noel A. Clark (University of Colorado)
TL;DR
This paper discusses how the phenomenon of 'heating by freezing' observed in nonequilibrium systems also occurs in equilibrium, specifically in two-dimensional colloidal systems with a periodic potential, indicating a broader applicability.
Contribution
It extends the concept of reentrant fluctuation-driven freezing from nonequilibrium to equilibrium systems, providing a new perspective on phase behavior in colloidal systems.
Findings
Reentrant freezing occurs in equilibrium systems.
The phenomenon can be realized in 2D colloidal systems with periodic potentials.
The study broadens understanding of fluctuation-driven phase transitions.
Abstract
We point out that the phenomenon ``heating by freezing'' discovered in nonequilibrium simulations by Helbing, et al. (PRL 84, 1240 (2000)) extends to equilibrium systems as well. We argue that such reentrant fluctuation-driven freezing can, for example, be realized in two-dimensional colloidal systems subjected to a one-dimensional periodic potential.
