Derivation of Fokker-Planck equation and its entropy production
Tânia Tomé, Mário J. de Oliveira
We derive the Fokker-Planck equation and its entropy production from the master equation. To this end we consider a discrete space of states where the master equation is defined an…
Stochastic thermodynamics of ecosystems
Tânia Tomè, Mário J. de Oliveira
We investigate the thermodynamics as well as the population dynamics of ecosystems based on a stochastic approach in which the number of individuals of the several species of the e…
Entropy production of the contact model
Tânia Tome, Mário J. de Oliveira
We propose an expression for the production of entropy for system described by a stochastic dynamics which is appropriate for the case where the reverse transition rate vanishes bu…
Classical stochastic approach to quantum mechanics and quantum thermodynamics
Mario J. de Olliveira
We derive the equations of quantum mechanics and quantum thermodynamics from the assumption that a quantum system can be described by an underlying classical system of particles. E…

We show that the dynamics of a quantum system can be represented by the dynamics of an underlying classical systems obeying the Hamilton equations of motion. This is achieved by tr…

From classical stochastic equations of motion we derive the quantum Schrödinger equation. The derivation is carried out by assuming that the real and imaginary parts of the wave fu…
Numerical exploration of the Aging effects in spin systems
Roberto da Silva, Tânia Tomé, Mário José de Oliveira
An interesting concept that has been underexplored in the context of time-dependent simulations is the correlation of total magnetization, %. One of its main advantages over…

We show that models of opinion formation and dissemination in a community of individuals can be framed within stochastic thermodynamics from which we can build a nonequilibrium the…

Alexander H. O. Wada, Mário J. de Oliveira
We have studied the critical properties of the contact process on a square lattice with quenched site dilution by Monte Carlo simulations. This was achieved by generating in advanc…

We have determined the thermal conductance of a system consisting of a two-level atom coupled to two quantum harmonic oscillators in contact with heat reservoirs at distinct temper…

We study a quantum XX chain coupled to two heat reservoirs that act on multiple-sites and are kept at different temperatures and chemical potentials. The baths are described by Lin…

Mario J. de Oliveira
We use a canonical quantization procedure to set up a quantum Fokker-Planck-Kramers equation that accounts for quantum dissipation in a thermal environment. The dissipation term is…
Thermal rectification in anharmonic chains under an energy-conserving noise
Pedro H. Guimarães, Gabriel T. Landi, Mário J. de Oliveira
Systems in which the heat flux depends on the direction of the flow are said to present thermal rectification. This effect has attracted much theoretical and experimental interest…

Boltzmann Temperature in out-of-equilibrium lattice gas
Mario J. de Oliveira, Alberto Petri
We investigate the quench of Ising and Potts models via Monte Carlo dynamics, and find that the distribution of the site-site interaction energy has the same form as in the equilib…
Sandpiles with height restrictions
Ronald Dickman, Tania Tome, Mario J. de Oliveira
We study stochastic sandpile models with a height restriction in one and two dimensions. A site can topple if it has a height of two, as in Manna's model, but, in contrast to previ…
