Intrinsic and extrinsic noise effects on the phase transition of swarming systems and related network models
Jaime A. Pimentel, Maximino Aldana, Cristián Huepe +1
We analyze order-disorder phase transitions driven by noise that occur in two kinds of network models closely related to the self-propelled model proposed by Vicsek et. al. to desc…

Dynamical Phase Transition in a Neural Network Model with Noise: an Exact Solution
Cristian Huepe, Maximino Aldana
The dynamical organization in the presence of noise of a Boolean neural network with random connections is analyzed. For low levels of noise, the system reaches a stationary state…
