Non-perturbative fixed point in a non-equilibrium phase transition
L. Canet, H. Chaté, B. Delamotte +2
We apply the non-perturbative renormalization group method to a class of out-of-equilibrium phase transitions (usually called ``parity conserving'' or, more properly, ``generalized…
Effective Langevin equations for the pair contact process with diffusion
I. Dornic, H. Chaté, M. A. Muñoz
We propose a system of coupled, real-valued, effective Langevin equations for the nonequilibrium phase transition exhibited by the pair contact process with diffusion (and similar…
Langevin description of critical phenomena with two symmetric absorbing states
Omar Al Hammal, Hugues Chaté, Ivan Dornic +1
On the basis of general considerations, we propose a Langevin equation accounting for critical phenomena occurring in the presence of two symmetric absorbing states. We study its p…
Effects of Static and Dynamic Disorder on the Performance of Neural Automata
J. J. Torres, J. Marro, P. L. Garrido +3
We report on both analytical and numerical results concerning stochastic Hopfield--like neural automata exhibiting the following (biologically inspired) features: (1) Neurons and s…
Influence of topology on the performance of a neural network
Joaquin J. Torres, Miguel A. Munoz, J. Marro +1
We studied the computational properties of an attractor neural network (ANN) with different network topologies. Though fully connected neural networks exhibit, in general, a good p…
Multiplicative Noise in Non-equilibrium Phase Transitions: A tutorial
Miguel A. Munoz
Stochastic phenomena in which the noise amplitude is proportional to the fluctuating variable itself, usually called {\it multiplicative noise}, appear ubiquitously in physics, bio…
