Minimal dissipation with viscoelastic baths in weakly driven processes
Pierre Nazé, Fabricio Q. Potiguar
We investigate the thermodynamics of overdamped systems weakly driven by time-dependent protocols while interacting with viscoelastic heat baths. Using a generalized Langevin equat…
Colloids in a periodic potential: driven lattice gas in continuous space
Fabricio Q. Potiguar, Ronald DIckman
Motivated by recent studies of colloidal particles in optical tweezer arrays, we study a two-dimensional model of a colloidal suspension in a periodic potential. The particles tend…
Driven lattice gas with nearest-neighbor exclusion: shear-like drive
Fabricio Q. Potiguar, Ronald Dickman
We present Monte Carlo simulations of the lattice gas with nearest-neighbor exclusion and Kawasaki (hopping) dynamics, under the influence of a nonuniform drive, on the square latt…
Numerical calculation of the energy relative fluctuation for a system in contact with a finite heat bath
F. Q. Potiguar, U. M. S. Costa
We use a scheme of separation of degrees of freedom for a system, in order to produce two systems with finite number of degrees of freedom. Our intent is to measure the energy squa…
Fluctuation of energy in the generalized thermostatistics
F. Q. Potiguar, U. M. S. Costa
We calculate the fluctuation of the energy of a system in Tsallis statistics following the finite heat bath canonical ensemble approach. We obtain this fluctuation as the second de…
Thermodynamics arising from Tsallis' thermostatistics
F. Q. Potiguar, U. M. S. Costa
We show, in two different ways, that the Tsallis' partition function and its derivatives are related to thermodynamic quantities such as entropy, internal energy, etc., in the same…
