Kinetic energy fluctuations and specific heat in generalized ensembles
Sergio Davis, Catalina Ruíz, Claudia Loyola +2
We derive an exact generalization of the well-known Lebowitz--Percus--Verlet (LPV) formula that relates the kinetic energy fluctuations of an isolated system to its specific heat.…
Superstatistics as the thermodynamic limit of driven classical systems
Sergio Davis, Claudia Loyola, Carlos Femenías +1
Superstatistics is an elegant framework for the description of steady-state thermodynamics, mostly used for systems with long-range interactions such as plasmas. In this work, we s…
Configurational density of states and melting of simple solids
Sergio Davis, Claudia Loyola, Joaquín Peralta
We analyze the behavior of the microcanonical and canonical caloric curves for a piecewise model of the configurational density of states of simple solids, in the context of meltin…
A novel Bayesian approach to the computation of the configurational density of states
Felipe Moreno, Sergio Davis, Joaquín Peralta
In this work we develop and implement a novel Bayesian method for computing the DOS of a system. This method is based on the use of a test function with adjustable parameters and w…
A portable and flexible implementation of the Wang--Landau algorithm in order to determine the Density of States
Felipe Moreno, Joaquín Peralta, Sergio Davis
In this work we develop an implementation of the Wang--Landau algorithm [Phys. Rev. Lett. \textbf{86}, 2050-2053 (2001)]. This algorithm allows us to find the density of states (DO…
Superheated solid state induced by a single collision event
Claudia Loyola, Sergio Davis, Joaquín Peralta
High-energy incident particles from both pulsed and continuous radiation sources can induce significant damage to the structure of a material by creating vacancy-interstitial pairs…
Deterministic physical systems under uncertain initial conditions: the case of maximum entropy applied to projectile motion
Alejandra Montecinos, Sergio Davis, Joaquín Peralta
The kinematics and dynamics of deterministic physical systems have been a foundation of our understanding of the world since Galileo and Newton. For real systems, however, uncertai…
Bayesian statistical modelling of microcanonical melting times at the superheated regime
Sergio Davis, Claudia Loyola, Joaquín Peralta
Homogeneous melting of superheated crystals at constant energy is a dynamical process, believed to be triggered by the accumulation of thermal vacancies and their self-diffusion. F…
Impact of Extreme Electrical Fields on Charge Density Distributions in Alloys
Claudia Loyola, Joaquin Peralta, Scott R. Broderick +1
The purpose of this work is to identify the field evaporation mechanism associated with charge density distribution under extreme fields, linking atom probe tomography (APT) experi…
Statistical distribution of thermal vacancies close to the melting point
María José Pozo, Sergio Davis, Joaquín Peralta
A detailed description of the statistical distribution of thermal vacancies near the melting point is presented, using copper as an example. As the temperature is increased, the av…
A Bayesian interpretation of abrupt phase transitions
Sergio Davis, Joaquín Peralta, Yasmín Navarrete +2
The formalism used in describing the thermodynamics of abrupt (or first-order) phase transitions is reviewed as an application of maximum entropy inference. In this treatment, we s…
