Counting solutions of the Bethe equations of the quantum group invariant open XXZ chain at roots of unity
Azat M. Gainutdinov, Wenrui Hao, Rafael I. Nepomechie +1
We consider the sl(2)_q-invariant open spin-1/2 XXZ quantum spin chain of finite length N. For the case that q is a root of unity, we propose a formula for the number of admissible…
Singular solutions, repeated roots and completeness for higher-spin chains
Wenrui Hao, Rafael I. Nepomechie, Andrew J. Sommese
We investigate the completeness of the solutions of the Bethe equations for the integrable spin-s isotropic (XXX) spin chain with periodic boundary conditions. Solutions containing…
On the completeness of solutions of Bethe's equations
Wenrui Hao, Rafael I. Nepomechie, Andrew J. Sommese
We consider the Bethe equations for the isotropic spin-1/2 Heisenberg quantum spin chain with periodic boundary conditions. We formulate a conjecture for the number of solutions wi…
