Ornstein-Uhlenbeck Process Driven by Multiple Dichotomous Noises
Silvio Kalaj, Dongho Lee, Enzo Marinari +3
We study a generalized Ornstein-Uhlenbeck process driven by a superposition of independent dichotomous noises with arbitrary fixed amplitudes and switching rates. Unlike the cl…

Convergence to the exact kinetics of the one-dimensional Riviera model
Pascal Viot
The Riviera model is a random sequential deposition model for house building on a lattice, in which a house cannot be built when both nearest-neighbor sites are already occupied. I…

Diffusing diffusivity model with dichotomous noise
Dongho Lee, Jae-Hyung Jeon, Pascal Viot +1
We study Langevin dynamics with stochastic diffusivity arising from fluctuations of the surrounding medium. The diffusivity is modeled as Ornstein-Uhlenbeck process driven by symme…
