Dynamics of Limit Cycle Oscillator Subject to General Noise
, 2010 The phase description is a powerful tool for analyzing noisy limit cycle oscillators. The method, however, has found only limited applications so far, because the present theory is applicable only to the Gaussian noise while noise in the real world often

Performance evaluation of Nakagami‐m fading with impulsive noise
IET Communications, 2021 The main motivation for considering noise to be Gaussian is the central limit theorem (CLT), which accounts for the perturbations that are additive in nature.

Decoherence due to telegraph and 1/f noise in Josephson qubits
, 2004 We study decoherence due to random telegraph and 1/f noise in Josephson qubits. We illustrate differences between gaussian and non gaussian effects at different working points and for different protocols.

Spectra for the product of Gaussian noises [PDF]
, 2012 Products of Gaussian noises often emerge as the result of non-linear detection techniques or as a parasitic effect, and their proper handling is important in many practical applications, including in fluctuation-enhanced sensing, indoor air or ...

Non-Gaussianity of Stochastic Gradient Noise
, 2019 What enables Stochastic Gradient Descent (SGD) to achieve better generalization than Gradient Descent (GD) in Neural Network training? This question has attracted much attention. In this paper, we study the distribution of the Stochastic Gradient Noise (SGN) vectors during the training. We observe that for batch sizes 256 and above, the distribution is

Dependence Balance Based Outer Bounds for Gaussian Networks with Cooperation and Feedback
, 2008 We obtain new outer bounds on the capacity regions of the two-user multiple access channel with generalized feedback (MAC-GF) and the two-user interference channel with generalized feedback (IC-GF).

Non-Markovian continuous-time quantum walks on lattices with dynamical noise [PDF]
, 2016 We address the dynamics of continuous-time quantum walks on one-dimensional disordered lattices inducing dynamical noise in the system. Noise is described as time-dependent fluctuations of the tunneling amplitudes between adjacent sites, and attention is

RESONANT ACTIVATION DRIVEN BY STRONGLY NON-GAUSSIAN NOISES [PDF]
Fluctuation and Noise Letters, 2004 The constructive role of non-Gaussian random fluctuations is studied in the context of the passage over the dichotomously switching potential barrier. Our attention focuses on the interplay of the effects of independent sources of fluctuations: an additive stable noise representing non-equilibrium external random force acting on the system and a ...

, 2003 The characteristic function of soliton phase jitter is found analytically when the soliton is perturbed by amplifier noise. In additional to that from amplitude jitter, the nonlinear phase noise due to frequency and timing jitter is also analyzed ...

A random walker on a ratchet potential: Effect of a non Gaussian noise [PDF]
, 2007 We analyze the effect of a colored non Gaussian noise on a model of a random walker moving along a ratchet potential. Such a model was motivated by the transport properties of motor proteins, like kinesin and myosin.
