We examine the metastable liquid phase of a supercooled gold nanocluster by studying the free energy landscape using the largest solidlike embryo as an order parameter. Just below freezing, the free energy exhibits a local minimum at small embryo sizes and a maximum at a larger critical embryo size. At T=660 K the free energy becomes a monotonically decreasing function of the order parameter as the liquid phase becomes unstable, indicating that we have reached a limit of stability. In contrast… Expand

Gas-liquid nucleation in a two dimensional system.
It is found that in two dimensions, the classical nucleation theory (CNT) fails to provide a reliable estimate of the free energy barrier and the reason for the inadequacy of the CNT can be attributed to the noncircular nature of the critical clusters. Expand
Crystal nucleation rate isotherms in Lennard-Jones liquids.
It is shown that the surface free energy at a curved crystal-liquid interface, as distinct from a flat interface, has also been determined at temperatures lower than the temperature of the terminal critical point of the melting curve and is a monotonically increasing function of the temperature.

On the occurrence of stable and supersaturated metastable states in metallic core-shell nanoparticles.
The model is able to address the question of whether or not core-shell nanoparticles have a limit of stability when they are under oversaturation conditions and one of the most striking results is the occurrence or not of a core- shell under undersaturation conditions depending on nanoparticle size.

Crystallization of Lennard-Jones nanodroplets: From near melting to deeply supercooled.
It is found that crystallization begins with hcp-fcc stacked precritical nuclei and differentiation to various end structures occurs when these embryos become critical, and the bulk melting temperature controls the rate, even though the solid-liquid coexistence temperature for the droplet is significantly lower.

Example of a Fluid-Phase Change Examined with MD Simulation: Evaporative Cooling of a Nanoscale Droplet.
The time and the temperature of inception were evaluated over 42 samples, which indicate the existence of a stability limit and the time evolution of the evaporating droplet properties was satisfactorily explained with a simple one-dimensional phase-change model. Expand
Evidence for a liquid-solid critical point in a simple monatomic system
It is commonly believed that the transition line separating a liquid and a solid cannot be interrupted by a critical point. This opinion is based on the traditional symmetry argument that anExpand
Scaling law for crystal nucleation time in glasses.
Results of molecular dynamics simulation reveal that the structural ordering in glasses becomes observable over "experimental" time-scale for the range of phase diagram with high values of pressure, and finds that the scaled values of the nucleation time in glassy systems are collapsed onto a single line reproducible by the power-law dependence.

Crossover from nucleation to spinodal decomposition in a condensing vapor.
The crossover from a purely nucleation-controlled transition toward spinodal decomposition in a condensing Lennard-Jones vapor is studied using molecular dynamics simulations and both the kinetics and the thermodynamics are analyzed by directly reconstructing the free energy of cluster formation.

Identification of critical nuclei in the rapid solidification via configuration heredity
A unique method able to distinguish the critical nucleus from numerous embryos is put forward on the basis of configuration heredities of clusters during rapid solidifications, and a good agreement with previous simulations and experiments in IT indicates this technique can be used to explore the early-stage of nucleation from atomistic levels.

Test of classical nucleation theory and mean first-passage time formalism on crystallization in the Lennard-Jones liquid
We perform molecular dynamics (MD) and Monte Carlo computer simulations to test the ability of the recently developed formalism of mean first-passage time (MFPT) [J. Wedekind, R. Strey, and D.Expand


Elucidating the mechanism of nucleation near the gas-liquid spinodal.
A multidimensional free energy surface of nucleation of the liquid phase from the parent supercooled and supersaturated vapor phase near the gas-liquid spinodal is constructed and the Becker-Doring constraint of having only one growing cluster in the system is removed. Expand
Freezing of a Lennard-Jones fluid: from nucleation to spinodal regime.
It is shown that in the nucleation regime, the freezing is a two-step process, and the formation of the critical nucleus is indeed preceded by the abrupt formation of a precritical crystallite from a density fluctuation in the fluid. Expand
Surface nucleation in the freezing of gold nanoparticles.
A simple partial wetting model is used that treats the crystal as a lens-shaped nucleus at the liquid-vapor interface and finds that the line tension plays an important role in the freezing of gold nanoparticles. Expand

A metastable limit for compressed liquid water
The transformation of liquid water to solid ice is typically a slow process. To cool a sample below the melting point requires some time, as does nucleation from the metastable liquid1, so freezingExpand
Computer simulation study of gas–liquid nucleation in a Lennard-Jones system
We report a computer-simulation study of homogeneous gas–liquid nucleation in a Lennard-Jones system. Using umbrella sampling, we compute the free energy of a cluster as a function of its size. AExpand
Test of classical nucleation theory on deeply supercooled high-pressure simulated silica.
This work quantifies how certain predictions of CNT break down in this deeply supercooled limit, while others [the n dependence of DeltaG(n)] are not as adversely affected. Expand
Molecular dynamics investigation of the transient regime in the freezing of salt clusters.
A new method of recording nucleation events was introduced that avoids the overshoots of nucleation rates that precluded the application of the Miloshev-Wu method in the subcritical region and provides information about the size of the critical nucleus. Expand
