Surface order-disorder phase transitions and percolation
M. Cecilia Gimenez, Felix Nieto, Antonio J. Ramirez-Pastor
In the present paper, the connection between surface order-disorder phase transitions and the percolating properties of the adsorbed phase has been studied. For this purpose, four…
The ground state energy of the Edwards-Anderson spin glass model with a parallel tempering Monte Carlo algorithm
F. Roma, S. Risau-Gusman, A. J. Ramirez-Pastor +2
We study the efficiency of parallel tempering Monte Carlo technique for calculating true ground states of the Edwards-Anderson spin glass model. Bimodal and Gaussian bond distribut…
Thermal Percolation for Interacting Monomers Adsorbed on Square Lattices
M. Cecilia Gimenez, Felix Nieto, Antonio J. Ramirez-Pastor
In this paper the percolation of monomers on a square lattice is studied as the particles interact with either repulsive or attractive energies. By means of a finite-size scaling a…
Critical behavior of long straight rigid rods on two-dimensional lattices: Theory and Monte Carlo simulations
D. A. Matoz-Fernandez, D. H. Linares, A. J. Ramirez-Pastor
The critical behavior of long straight rigid rods of length (-mers) on square and triangular lattices at intermediate density has been studied. A nematic phase, characterize…
Monte Carlo simulation of metal deposition on foreign substrates
M. Cecilia Gimenez, Antonio J. Ramirez-Pastor, Ezequiel P. M. Leiva
The deposition of a metal on a foreign substrate is studied by means of grand canonical Monte Carlo simulations and a lattice-gas model with pair potential interactions between nea…
