Abstract
|
We study large deviations for a Markov process on curves in
mimicking the motion of an interface. Our dynamics can be tuned with a parameter
,
which plays the role of an inverse temperature and coincides at
with the zero-temperature Ising model Glauber dynamics, where curves
correspond to the boundaries of droplets of one phase immersed in a sea of the
other one. The diffusion coefficient and mobility of the model are identified
and correspond to those predicted in the literature. We prove that contours
typically follow a motion by curvature with an influence of the parameter
and establish large deviation bounds at all large enough
.
