KPZ-type fluctuation exponents for interacting diffusions in equilibrium
KPZ-type fluctuation exponents for interacting diffusions in equilibrium
We consider systems of N diffusions in equilibrium interacting through a potential V. We study a "height function," which, for the special choice V(x)=eāx, coincides with the partition function of a stationary semidiscrete polymer, also known as the (stationary) O'ConnellāYor polymer. For a general class of smooth convex potentials (generalizing ā¦
