Distribution of currents in a system of active particles with biased hops and Ising interactions
Evgeniy Khain, Shriram Ramesh, Vladimir Chernyak
We consider an ensemble of particles performing a biased random walk on a two-dimensional lattice. Due to the adhesion between particles (nearest-neighbor Ising interactions), the…
Speed fluctuations of a stochastic Huxley-Zel'dovich front
Evgeniy Khain, Baruch Meerson, Pavel V. Sasorov
The empirical speed of travelling reaction-diffusion fronts fluctuates due to the intrinsic shot noise of the reactions and diffusion. Here we study the long-time front speed fluct…
Velocity fluctuations of stochastic reaction fronts propagating into an unstable state: strongly pushed fronts
Evgeniy Khain, Baruch Meerson, Pavel Sasorov
The empirical velocity of a reaction-diffusion front, propagating into an unstable state, fluctuates because of the shot noises of the reactions and diffusion. Under certain condit…
Noise induces rare events in granular media
Evgeniy Khain, Leonard M. Sander
The granular Leidenfrost effect (B. Meerson et al, Phys. Rev. Lett. {\bf 91}, 024301 (2003), P. Eshuis et al, Phys. Rev. Lett. {\bf 95}, 258001 (2005)) is the levitation of a mass…
Velocity fluctuations of noisy reaction fronts propagating into a metastable state: testing theory in stochastic simulations
Evgeniy Khain, Baruch Meerson
The position of a reaction front, propagating into a metastable state, fluctuates because of the shot noise of reactions and diffusion. A recent theory [B. Meerson, P.V. Sasorov, a…
Fluctuations and stability in front propagation
E. Khain, Y. T. Lin, L. M. Sander
Propagating fronts arising from bistable reaction-diffusion equations are a purely deterministic effect. Stochastic reaction-diffusion processes also show front propagation which c…
