A quasi-elastic regime for vibrated granular gases

Aumaître, S.; Alastuey, A.; Fauve, S. - In: The European Physical Journal B - Condensed Matter and … 54 (2006) 2, pp. 263-266

Using simple scaling arguments and two-dimensional numerical simulations of a granular gas excited by vibrating one of the container boundaries, we study a double limit of small 1-r and large L, where r is the restitution coefficient and L the size of the container. We show that if the particle...

Convective and absolute instabilities in the subcritical Ginzburg-Landau equation

Colet, P.; Walgraef, D.; Miguel, M. - In: The European Physical Journal B - Condensed Matter and … 11 (1999) 3, pp. 517-524

We study the nature of the instability of the homogeneous steady states of the subcritical real Ginzburg-Landau equation in the presence of group velocity. The shift of the absolute instability threshold of the trivial steady state, induced by the destabilizing cubic nonlinearities, is confirmed...

Role of noise in a market model with stochastic volatility

Bonanno, G.; Valenti, D.; Spagnolo, B. - In: The European Physical Journal B - Condensed Matter and … 53 (2006) 3, pp. 405-409

correlation between the two Wiener processes, which model the two white noise sources. This model can be useful to describe the … noise on the statistical properties of the escape time with reference to the noise enhanced stability (NES) phenomenon, that … is the noise induced enhancement of the lifetime of a metastable state. We observe NES effect in our model with …
