Monte Carlo simulations of crystal nuclei coexisting with the fluid phase in thermal equilibrium in finite volumes are presented and analyzed, for fluid densities from dense melts to the vapor. Generalizing the lever rule for two-phase coexistence in the canonical ensemble to finite volume, "measurements" of the nucleus volume together with the pressure and chemical potential of the surrounding fluid allows us to extract the surface free energy of the nucleus. Neither the knowledge of the (in… 
The phase coexistence method to obtain surface free energies and nucleation barriers: a brief review
ABSTRACT A recently developed method where one analyses the finite size effects associated with liquid–solid phase equilibria including vapour–crystal coexistence is briefly reviewed. It is shown
Parasitic crystallization of colloidal electrolytes: growing a metastable crystal from the nucleus of a stable phase.
The results show that at a high packing fraction, there is a cross-over between the nucleation of the CsCl structure and that of a substitutionally disordered fcc phase, despite the CuAu crystal being the most stable phase.
Equivalence between condensation and boiling in a Lennard-Jones fluid.
Condensation and boiling can be viewed as two sides of the same coin by combining the data coming from drops and bubbles to obtain estimates of the Tolman length, a parameter that allows describing the curvature dependence of the surface tension in a theoretical framework.
The Young-Laplace equation for a solid-liquid interface.
It is shown that in a Gibbsian description of the thermodynamics of a curved solid-liquid interface in equilibrium, the choice of theThermodynamic (rather than mechanical) pressure is required, as suggested by Tolman for the liquid-gas scenario.
Nucleus-size pinning for determination of nucleation free-energy barriers and nucleus geometry.
A generalization of CNT is used to account for nucleus asphericity and predict nucleation free-energy barriers for gyrobifastigia and these predictions of nuclei shape and barriers are validated by independent umbrella sampling calculations.
Crystallization of hard spheres revisited. II. Thermodynamic modeling, nucleation work, and the surface of tension.
This work probes the crystallization of hard spheres over the full range from close to coexistence to the spinodal regime, and shows how to extract the pressure difference between the solid droplet and ambient liquid.
Crystal nucleation along an entropic pathway: Teaching liquids how to transition
We combine machine learning (ML) with Monte Carlo (MC) simulations to study the crystal nucleation process. Using ML, we evaluate the canonical partition function of the system over the range of
Seeding approach to nucleation in the NVT ensemble: The case of bubble cavitation in overstretched Lennard Jones fluids.
It is shown that, in the NVT ensemble, it is possible to equilibrate and stabilise critical bubbles for a long time and the nucleation rate inferred from NVT-S Seeding is fully consistent with that coming from NPT-Seeding.
Suppression of ice nucleation in supercooled water under temperature gradients
Understanding the behaviours of ice nucleation in non-isothermal conditions is of great importance for the preparation and retention of supercooled water. Here ice nucleation in supercooled water
