Localization Transition for Polymers in Poissonian Medium
Directed polymers random environment Probability
<
2012/6/25
We study a model of directed polymers in random environment in dimension $1+d$, given by a Brownian motion in a Poissonian potential. We study the effect of the density and the strength of inhomogenei...
