Abstract: C1.00219 : Long-range order in a system of thermal Brownian particles
Author:
We present a model that exhibits an order-disorder phase
transition in two spatial-dimensions. The model considers a
collection of $N$ thermal Brownian particles moving in a square
of length $L$ subjected to periodic boundary conditions and to
velocity-alignment forces. The alignment force affects only the
velocity direction in a way that it makes it equal to the
velocity direction of the nearby group. Our results contrast with
those obtained from the well known model of Vicsek {\it et al.}
[Phys. Rev. Lett. {\bf 75}, 1226 (1995)] where such a transition
occurs out of equilibrium.
