Baity Jesi, Marco ; Calore, E. ; Cruz, A. ; Fernández Pérez, Luis Antonio ; Gil-Narvión,, J. M. ; Gordillo-Guerrero, A. ; Íñiguez, D. ; Maiorano, A. ; Marinari, E. ; Martín Mayor, Víctor ; Moreno-Gordo, J. ; Muñoz Sudupe, Antonio ; Navarro, D. ; Parisi, G. ; Pérez-Gaviro, S. ; Ricci-Tersenghi, F. ; Ruiz-Lorenzo, J. 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
We explore the capacity of neural networks to detect a symmetry with complex local and non-local patterns: the gauge symmetry Z(2). This symmetry is present in physical problems from topological transitions to quantum chromodynamics, and control[...]texto impreso
Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Muñoz Sudupe, Antonio ; Seoane, B. ; Yllanes, D. ; otros, ... | American Physical Society | 2011-11-20We study the sample-to-sample fluctuations of the overlap probability densities from large-scale equilibrium simulations of the three-dimensional Edwards-Anderson spin glass below the critical temperature. Ultrametricity, stochastic stability, a[...]texto impreso
Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Seoane, B. ; Verrocchio, P. | American Physical Society | 2010-08-05We study a polydisperse soft-spheres model for colloids by means of microcanonical Monte Carlo simulations. We consider a polydispersity as high as 24%. Although solidification occurs, neither a crystal nor an amorphous state are thermodynamical[...]texto impreso
Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Parisi, G. ; Seoane, B. | American Physical Society | 2010-04-02We present a mean field model for spin glasses with a natural notion of distance built in, namely, the Edwards-Anderson model on the diluted D-dimensional unit hypercube in the limit of large D. We show that finite D effects are strongly depende[...]texto impreso
Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Muñoz Sudupe, Antonio ; Seoane, B. ; Yllanes, D. ; otros, ... | American Physical Society | 2010-10-20We numerically study the aging properties of the dynamical heterogeneities in the Ising spin glass. We find that a phase transition takes place during the aging process. Statics-dynamics correspondence implies that systems of finite size in equi[...]texto impreso
Fernández Pérez, Luis Antonio ; Martín Mayor, Víctor ; Parisi, G. ; Seoane, B. | EPL Association, European Physical Society | 2013-10-07Temperature chaos has often been reported in the literature as a rare-event–driven phenomenon. However, this fact has always been ignored in the data analysis, thus erasing the signal of the chaotic behavior (still rare in the sizes achieved) an[...]
