Entropy has become increasingly central to characterize, understand, and even guide assembly, self-organization, and phase transition processes. In this work, we build on the analogous role of partition functions (or free energies) in isothermal ensembles and that of entropy in adiabatic ensembles. In particular, we show that the grand-isobaric adiabatic (μ, P, R) ensemble, or Ray ensemble, provides a direct route to determine the entropy. This allows us to follow the variations of entropy with…

Entropy determination for mixtures in the adiabatic grand-isobaric ensemble.

This work generalizes the grand-isobaric ensemble to mixtures and develops a Monte Carlo algorithm for the rapid determination of entropy in these systems, which performs very well both on systems modeled with simple potentials and with complex many-body force fields.

Entropy scaling close to criticality: From simple to metallic systems.

This work focuses on the behavior of entropy along the vapor-liquid phase coexistence and identifies how the difference in entropy between the two coexisting phases vary in ideal and metallic systems along the coexistence curve.

Entropy in Molecular Fluids: Interplay between Interaction Complexity and Criticality.

Using flat-histogram simulations, the critical entropy of molecular fluids is determined and the transition occurs symmetrically from an entropic standpoint and functional forms that characterize the relation between thermodynamic variables and entropy along the coexistence curve up to the critical point are identified.



On the distance between A and B in molecular configuration space

ABSTRACT In this brief review, we discuss the question of calculating the distance between different molecular configurations. We focus on the theoretical basis of different existing methods for this

Can Ordered Precursors Promote the Nucleation of Solid Solutions?

This work identifies a new nucleation mechanism (liquid→L1_{2} precursor→solid solution) involving a chemically ordered intermediate that is more organized than the end product and shows that this mechanism is composition dependent.

A simple empirical N-body potential for transition metals

Abstract A simple form of multi-ion interaction has been constructed for the purpose of atomistic simulation of transition metals. The model energy consists of a bonding term, which is the

A molecular dynamics simulation method which can generate configurations belonging to the canonical (T, V, N) ensemble or the constant temperature constant pressure (T, P, N) ensemble, is proposed.

Fourth adiabatic ensemble

The statistical mechanics of a new adiabatic ensemble, which allows volume and particle fluctuations, is presented. Characteristic fluctuation formulas and suitable response functions are derived.

A new adiabatic ensemble with particle fluctuations

The statistical mechanics of a new shell ensemble, which is the adiabatic counterpart of the grand canonical ensemble, is developed through its analogy to the microcanonical ensemble and to the
