Abstract:

We consider a model of a directed polymer in an environment of Poisson random walks. We prove that under diffusive scaling, as temperature goes to infinity, the partition function converges to a stochastic heat equation with a multiplicative noise, whose covariance is long-range and singular (more precisely, the heat kernel). Based on joint work with Jian Song, Rongfeng Sun, Lihu Xu
