TITLE: On large time asymptotic of Ornstein-Uhlenbeck process in Poisson potential
ABSTRACT: We consider the following random motion in random media model:an Ornstein-Uhlenbeck(O-U) process travels in R^d space, and the space isfilled with random media which is modeled by a homogeneous Poisson pointprocess. We are interested in the evolution of accumulated energy of the
O-U process from the Poisson random media up to time t. The exponentialmoment of the accumulated energy have many connections in other areas,such as the solution of certain parabolic PDEs, trapping problems ofrandom polymers in chemistry, and so on. In this talk, I would like totalk about the long time asymptotic for the exponential moment of theenergy, in two scenarios: the quenched case and the annealed case.
