J. ; Schifano, S. F. ; Seoane, B. ; Tarancón, A. ; Tripiccione, R. ; Yllanes, D. | Amer Physical Soc | 2018-06-28Experiments on spin glasses can now make precise measurements of the exponent zðTÞ governing the growth of glassy domains, while our computational capabilities allow us to make quantitative predictions for experimental scales. However, experimen[...]texto impreso
Fernández Pérez, Luis Antonio ; Marinari, E. ; Martín Mayor, Víctor ; Parisi, V. ; Ruiz Lorenzo, J. J. | IOP publishing ltd | 2019-05-31Recent high precision experimental results on spin-glass films ask for a detailed understanding of the domain-growth dynamics of two-dimensional spin glasses. To achieve this goal, we numerically simulate the out-equilibrium dynamics of the Isin[...]texto impreso
We study the phase diagram of the four-dimensional O(4) model with first- (?_(1)) and second- (?2) neighbor couplings, especially in the ?_(2)texto impreso
Ballesteros, H. G. ; Carmona, J. M. ; Fernández Pérez, Luis Antonio ; Tarancón, A. | Elsevier Science BV | 1998-02-12We study the antiferromagnetic O(N). N model in the F_(4) lattice. Monte Carlo simulations are applied for investigating the behavior of the transition for N = 2,3. The numerical results show a first order nature but with a large correlation len[...]texto impreso
Alonso, J. L. ; Ballesteros, H.G. ; Campos, I. ; Carmona, J. M. ; Clemente Gallardo, J. ; Fernández Pérez, Luis Antonio ; Íñiguez, D. ; Martín Mayor, Víctor ; Muñoz Sudupe, Antonio ; Tarancón, A. ; Ullod, C. L. | Elsevier | 1997-02We present antiferromagnetism as a mechanism capable of modifying substantially the phase diagram and the critical behaviour of statistical mechanical models. This is particularly relevant in four dimensions, due to the connection between second[...]texto impreso

We discuss the relation between the phase of Polyakov loops and the sea quarks boundary conditions. We report prefiminary results about the HMC autocorrelation [...]texto impreso

Baños, R.A. ; Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Young, A.P. | American Physical Society | 2012-10-17We compare the critical behavior of the short-range Ising spin glass with a spin glass with long-range interactions which fall off as a power ? of the distance. We show that there is a value of ? of the long-range model for which the critical be[...]texto impreso
Ballesteros, H. G. ; Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Muñoz Sudupe, Antonio ; Parisi, G. ; Ruiz Lorenzo, J. J. | American Physical Society | 2000-02-01We have studied numerically the effect of quenched site dilution on a weak first-order phase transition in three dimensions. We have simulated the site diluted three-states Potts model studying in detail the secondorder region of its phase diagr[...]texto impreso
Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Yllanes, D. | American Physical Society | 2011-09-26We study the critical behavior of the diluted antiferromagnet in a field with the tethered Monte Carlo formalism. We compute the critical exponents (including the elusive hyperscaling violations exponent ?). Our results provide a comprehensive d[...]texto impreso
Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Verrocchio, P. | American Physical Society | 2006-02-14We show numeric evidence that, at low enough temperatures, the potential energy density of a glass-forming liquid fluctuates over length scales much larger than the interaction range. We focus on the behavior of translationally invariant quantit[...]texto impreso

L. ; Ungil, C. | American Physical Society | 2000-12-01We have simulated, using parallel tempering, the three-dimensional Ising spin glass model with binary couplings in a helicoidal geometry. The largest lattice (L520) has been studied using a dedicated computer (the SUE machine). We have obtained,[...]texto impreso
Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Muñoz Sudupe, Antonio ; otros, ... | IOP Publishing | 2010-05-05We study the 3D Disordered Potts Model with p = 5 and p = 6. Our numerical simulations (that severely slow down for increasing p) detect a very clear spin glass phase transition. We evaluate the critical exponents and the critical value of the t[...]texto impreso
Ballesteros, H. G. ; Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Muñoz Sudupe, Antonio | Elsevier | 1997-02We present the results of a Monte Carlo simulation of the antiferromagnetic RP^2 model in three dimensions. With finite-size scaling techniques we accurately measure the critical exponents and compare them with those of O(N) models. We are able [...]
