Integrable Structure For The Multitime Distribution Of TASEP
To participate in this seminar, please register HERE.
Consider the continuous time totally asymmetric simple exclusion process (TASEP) on the line with the step initial condition. The infinite time scaling limit of this model belongs to the Kardar-Parisi-Zhang (KPZ) universality class. Denote its random space-time height function as h(t,y). The one point distribution as the function of three variables is the tau function of the Kadomtsev-Petviashvili (KPII) equation. The multitime distribution has the representation as the multiple contour integral of the integrable Fredholm determinant. We study the differential equations associated with it.
