$T$-$Q$ relations for the integrable two-species asymmetric simple exclusion process with open boundaries

Mathematical Physics 2019-05-07 v1 math.MP

Abstract

We study the integrable two-species asymmetric simple exclusion process (ASEP) for two inequivalent types of open, non particle conserving boundary conditions. Employing the nested off-diagonal Bethe ansatz method, we construct for each case the corresponding homogeneous TT-QQ relations and obtain the Bethe ansatz equations. Numerical checks for small system sizes show completeness for some Bethe ansatz equations, and partial completeness for others.
