Wronskian-type formula for inhomogeneous $TQ$ equations
Rafael I. Nepomechie Department of Physics, University of Miami, Coral Gables, Florida, USA
Abstract:
It is known that the transfer-matrix eigenvalues of the isotropic open Heisenberg quantum spin-1/2 chain with nondiagonal boundary magnetic fields satisfy a $TQ$ equation with an inhomogeneous term. We derive a discrete Wronskian-type formula relating a solution of this inhomogeneous $TQ$ equation to the corresponding solution of a dual inhomogeneous $TQ$ equation.
Keywords:
Bethe ansatz, $TQ$ equation, discrete Wronskian, boundary integrability.
