Integrable Boundary Conditions in Asymmetric Diffusion Processes
Akira FUJII
Abstract
We study the asymptotic diffusion processes with (generally nonlocal) open boundaries in one dimension which are exactly solvable by means of the recently developed recursion formula. We investigate the stationary states, which cannot be determined in an elementary way. We give the equation which includes an auxiliary parameter and determines possible boundary conditions for the model to be solved exactly. With the help of that equation, we analyze the density current and concentration. We classify the phases according to them.
