Tracy–Widom fluctuations for perturbations of the log-gamma polymer in intermediate disorder
Tracy–Widom fluctuations for perturbations of the log-gamma polymer in intermediate disorder
The free-energy fluctuations of the discrete directed polymer in $1+1$ dimensions is conjecturally in the Tracy–Widom universality class at all finite temperatures and in the intermediate disorder regime. Seppäläinen's log-gamma polymer was proven to have GUE Tracy–Widom fluctuations in a restricted temperature range by Borodin, Corwin and Remenik [Comm. Math. …
