On low-sampling-rate Kramers-Moyal coefficients
C. Anteneodo, S. M. Duarte Queiros
We analyze the impact of the sampling interval on the estimation of Kramers-Moyal coefficients. We obtain the finite-time expressions of these coefficients for several standard pro…
Describing the ground state of quantum systems through statistical mechanics
Andre M. C. Souza
We present a statistical mechanics description to study the ground state of quantum systems. In this approach, averages for the complete system are calculated over the non-interact…
Lyapunov exponent of the random frequency oscillator: cumulant expansion approach
C. Anteneodo, R. O. Vallejos
We consider a one-dimensional harmonic oscillator with a random frequency, focusing on both the standard and the generalized Lyapunov exponents, and respectively. We…
Time evolution towards q-Gaussian stationary states through unified Ito-Stratonovich stochastic equation
B. Coutinho dos Santos, C. Tsallis
We consider a class of single-particle one-dimensional stochastic equations which include external field, additive and multiplicative noises. We use a parameter which…
A generalization of the cumulant expansion. Application to a scale-invariant probabilistic model
Antonio Rodriguez, Constantino Tsallis
As well known, cumulant expansion is an alternative way to moment expansion to fully characterize probability distributions provided all the moments exist. If this is not the case,…
