Boundary energy of the open XXX chain with a non-diagonal boundary term
Rafael I. Nepomechie, Chunguang Wang
We analyze the ground state of the open spin-1/2 isotropic quantum spin chain with a non-diagonal boundary term using a recently proposed Bethe ansatz solution. As the coefficient…

Algebraic Bethe ansatz for singular solutions
Rafael I. Nepomechie, Chunguang Wang
The Bethe equations for the isotropic periodic spin-1/2 Heisenberg chain with N sites have solutions containing i/2, -i/2 that are singular: both the corresponding energy and the a…
