A note on a boundary sine-Gordon model at the free-Fermion point
Rajan Murgan
We investigate the free-Fermion point of a boundary sine-Gordon model with nondiagonal boundary interactions for the ground state using auxiliary functions, obtained from T-Q equat…
A note on the IR limit of the NLIEs of boundary supersymmetric sine-Gordon model
Rajan Murgan
We consider the infrared (IR) limit of the nonlinear integral equations (NLIEs) for the boundary supersymmetric sine-Gordon (BSSG) model, previously obtained from the NLIEs for the…
On the NLIE of (inhomogeneous) open spin-1 XXZ chain with general integrable boundary terms
Rajan Murgan
Starting from the T-Q equations of the open spin-1 XXZ quantum spin chain with general integrable boundary terms, for values of the boundary parameters which satisfy a certain cons…
NLIE and finite size effects of the spin-1/2 XXZ and sine-Gordon models with two boundaries revisited
Rajan Murgan
Starting from the T-Q equation of an open integrable spin-1/2 XXZ quantum spin chain with nondiagonal boundary terms, we derive a nonlinear integral equation (NLIE) of the sine-Gor…
A note on open-chain transfer matrices from q-deformed su(2|2) S-matrices
Rajan Murgan
In this note, we perform Sklyanin's construction of commuting open-chain/boundary transfer matrices to the q-deformed SU(2|2) bulk S-matrix of Beisert and Koroteev and a correspond…
Bethe ansatz of the open spin-s XXZ chain with nondiagonal boundary terms
Rajan Murgan
We consider the open spin-s XXZ quantum spin chain with nondiagonal boundary terms. By exploiting certain functional relations at roots of unity, we propose the Bethe ansatz soluti…
