Using concepts from classical density functional theory, we investigate the freezing of a two-dimensional system of ultrasoft particles in a one-dimensional external potential, a phenomenon often called laser-induced freezing (LIF). In the first part of the paper, we present numerical results from free minimization of a mean-field density functional for a system of particles interacting via the GEM-4 potential. We show that the system does indeed display a LIF transition, although the…

Freezing of a soft-core fluid in a one-dimensional potential: appearance of a locked smectic phase
ABSTRACT We investigate the phase behaviour of a two-dimensional colloidal model system of ultra-soft particles on a substrate which varies periodically along one spatial direction. Our calculations
Freezing and reentrant melting of hard disks in a one-dimensional potential: Predictions based on a pressure-balance equation.
The purpose of the present work is to calculate the freezing and reentrant melting phase diagram based on information from the bulk system using an integrated pressure-balance equation derived from density functional theory and defines a measure to quantify the influence of registration effects that qualitatively explain reentrants melting.


Phase transitions of soft disks in external periodic potentials: a Monte Carlo study.
The simulations show that the system of soft disks behaves in a fashion similar to charge stabilized colloids, which are known to undergo an initial freezing, followed by a remelting transition as the amplitude of the imposed, modulating field produced by crossed laser beams is steadily increased.
Fluid and solid phases of the Gaussian core model
We study the structural and thermodynamic properties of a model of point particles interacting by means of a Gaussian pair potential first introduced by Stillinger (Stillinger F H 1976 J. Chem. Phys.

It is shown that the Gaussian core model of particles interacting via a penetrable repulsive Gaussian potential behaves as a weakly correlated "mean-field fluid" over a surprisingly wide density and temperature range.
Why do ultrasoft repulsive particles cluster and crystallize? Analytical results from density-functional theory.
We demonstrate the accuracy of the hypernetted chain closure and of the mean-field approximation for the calculation of the fluid-state properties of systems interacting by means of bounded and
