A robust balancing mechanism for spiking neural networks
Antonio Politi, Alessandro Torcini
Dynamical balance of excitation and inhibition is usually invoked to explain the irregular low firing activity observed in the cortex. We propose a robust nonlinear balancing mecha…
Nearly Hamiltonian dynamics of laser systems
Antonio Politi, Serhiy Yanchuk, Giovanni Giacomelli
The Arecchi-Bonifacio (or Maxwell-Bloch) model is the benchmark for the description of active optical media. However, in the presence of a fast relaxation of the atomic polarizatio…
Onsager coefficients in a coupled-transport model displaying a condensation transition
Stefano Iubini, Antonio Politi, Paolo Politi
We study nonequilibrium steady states of a one-dimensional stochastic model, originally introduced as an approximation of the Discrete Nonlinear Schrödinger equation. This model is…
Frozen dynamics of a breather induced by an adiabatic invariant
Antonio Politi, Paolo Politi, Stefano Iubini
The Discrete Nonlinear Schrödinger (DNLS) equation is a Hamiltonian model displaying an extremely slow relaxation process when discrete breathers appear in the system. In [Iubini S…
Spaceless description of active optical media
Giovanni Giacomelli, Serhiy Yanchuk, Antonio Politi
The acclaimed Maxwell-Bloch (or Arecchi-Bonifacio) equations are a valid dynamical model, effectively describing wave propagation in nonlinear optical media: from the amplification…
Coherent oscillations in balanced neural networks driven by endogenous fluctuations
Matteo Di Volo, Marco Segneri, Denis Goldobin +2
We present a detailed analysis of the dynamical regimes observed in a balanced network of identical Quadratic Integrate-and-Fire (QIF) neurons with a sparse connectivity for homoge…
