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

Fernández Pérez, Luis Antonio ; Maiorano, A. ; Marinari, E. ; Martín Mayor, Víctor ; Navarro, D. ; Sciretti, D. ; Tarancón, A. ; Velasco, J. L. | American Physical Society | 2008-03-24We investigate the critical properties of the four-state commutative random permutation glassy Potts model in three and four dimensions by means of Monte Carlo simulations and a finite-size scaling analysis. By using a field programmable gate ar[...]texto impreso
Billoire, A. ; Maiorano, A. ; Marinari, E. ; Martín Mayor, Víctor ; Yllanes, D. | American Physical Society | 2014-09-08We use a sample-dependent analysis, based on medians and quantiles, to analyze the behavior of the overlap probability distribution of the Sherrington-Kirkpatrick and 3D Edwards-Anderson models of Ising spin glasses. We find that this approach i[...]texto impreso
Fernández Pérez, Luis Antonio ; Marinari, E. ; Martín Mayor, Víctor ; Paga, I ; Ruiz Lorenzo, J. J. | American Physical Society | 2019-11-11Motivated by recent experiments of exceptional accuracy, we study numerically the spin-glass dynamics in a film geometry. We cover all the relevant time regimes, from picoseconds to equilibrium, at temperatures at and below the 3D critical point[...]texto impreso

J. | IOP Publishing | 2018-03-02We have introduced a variational method to improve the computation of integrated correlation times in the Parallel Tempering Dynamics, obtaining a better estimate (a lower bound, at least) of the exponential correlation time. Using this determin[...]texto impreso
We present a general and powerful numerical method useful to study the density matrix of spin models. We apply the method to finite-dimensional spin glasses, and analyze in detail the four-dimensional EdwardsAnderson model with Gaussian quenched[...]texto impreso
Billoire, A. ; Fernández Pérez, Luis Antonio ; Maiorano, A. ; Marinari, E. ; Martín Mayor, Víctor ; Yllanes, D. | IOP Publishing | 2011-10Using the results of large scale numerical simulations we study the probability distribution of the pseudo critical temperature for the three dimensional Edwards Anderson Ising spin glass and for the fully connected Sherrington-Kirkpatrick model[...]texto impreso

J. | American Physical Society | 2017-07-21Chaotic size dependence makes it extremely difficult to take the thermodynamic limit in disordered systems. Instead, the metastate, which is a distribution over thermodynamic states, might have a smooth limit. So far, studies of the metastate ha[...]texto impreso
Fernández Pérez, Luis Antonio ; Marinari, E. ; Martín Mayor, Víctor ; Parisi, G. ; Ruiz Lorenzo, J.J. | IOP publishing ltd | 2018-10We consider the spatial correlation function of the two-dimensional Ising spin glass under out-equilibrium conditions. We pay special attention to the scaling limit reached upon approaching zero temperature. The field-theory of a non-interacting[...]texto impreso
We study the temperature-dilution phase diagram of a site-diluted Heisenberg antiferromagnet on a facecertered-cubic lattice, with and without the Dzyaloshinskii-Moriya anisotropic term, fixed to realistic microscopic parameters for IIB_(1-x)Mn_[...]texto impreso
Fernández Pérez, Luis Antonio ; Marinari, E. ; Martín Mayor, Víctor ; Parisi, G. ; Yllanes, D. | IOP Publishing | 2016-12-01Temperature chaos plays a role in important effects, like for example memory and rejuvenation, in spin glasses, colloids, polymers. We numerically investigate temperature chaos in spin glasses, exploiting its recent characterization as a rare-ev[...]texto impreso
Fernández Pérez, Luis Antonio ; Marinari, E. ; Martín Mayor, Víctor ; Parisi, G. ; Ruiz Lorenzo, J. J. | American Physical Society | 2016-07-01We use finite size scaling to study Ising spin glasses in two spatial dimensions. The issue of universality is addressed by comparing discrete and continuous probability distributions for the quenched random couplings. The sophisticated temperat[...]
