Survival of a Diffusing Particle in a Transverse Flow Field
Alan J. Bray, Panos Gonos
We consider a particle diffusing in the y-direction, dy/dt=η(t) where η(t) is Gaussian white noise, and subject to a transverse flow field in the x-direction, dx/dt=f(y), where x \…

Persistence in systems with conserved order parameter
P. Gonos, A. J. Bray
We consider the low-temperature coarsening dynamics of a one-dimensional Ising ferromagnet with conserved Kawasaki-like dynamics in the domain representation. Domains diffuse with…

Survival of a Diffusing Particle in a Transverse Shear Flow: A First-Passage Problem with Continuously Varying Persistence Exponent
Alan J. Bray, Panos Gonos
We consider a particle diffusing in the y-direction, dy/dt=η(t), subject to a transverse shear flow in the x-direction, dx/dt=f(y), where x \ge 0 and x=0 is an absorbing boundary.…
