Fernández Pérez, Luis Antonio ; Gordillo Guerrero, A. ; Martín Mayor, Víctor ; Ruiz Lorenzo, J. J. | American Institute of Physics | 2008We present a detailed numerical study on the effects of adding quenched impurities to a three dimensional system which in the pure case undergoes a strong first order phase transition (specifically, the ferromagnetic/paramagnetic transition of t[...]texto impreso
Fernández Pérez, Luis Antonio ; Gordillo Guerrero, A. ; Martín Mayor, Víctor ; Ruiz Lorenzo, J. J. | American Physical Society | 2008-02-08We present the first detailed numerical study in three dimensions of a first-order phase transition that remains first order in the presence of quenched disorder (specifically, the ferromagnetic-paramagnetic transition of the site-diluted four s[...]texto impreso
Fernández Pérez, Luis Antonio ; Gordillo Guerrero, A. ; Martín Mayor, Víctor ; Ruiz Lorenzo, J. J. | American Physical Society | 2009-11-06A microcanonical finite-size ansatz in terms of quantities measurable in a finite lattice allows extending phenomenological renormalization the so-called quotients method to the microcanonical ensemble. The ansatz is tested numerically in two m[...]texto impreso
Fernández Pérez, Luis Antonio ; Gordillo Guerrero, A. ; Martín Mayor, Víctor ; Ruiz Lorenzo, J.J. | American Physical Society | 2012-11-16We present a microcanonical Monte Carlo simulation of the site-diluted Potts model in three dimensions with eight internal states, partly carried out on the citizen supercomputer Ibercivis. Upon dilution, the pure model’s first-order transition [...]
