Algebraic Bethe ansatz for singular solutions

open access: yes, 2013
The Bethe equations for the isotropic periodic spin-1 2 Heisenberg chain with N sites have solutions containing ±i 2 that are singular: both the corresponding energy and the algebraic Bethe ansatz vector are divergent.

The Roaming Bethe Roots: An Effective Bethe Ansatz Beyond Integrability

open access: yes
We propose an effective Bethe ansatz (EBA) for solving quantum many-body systems near an integrable point. Our approach retains the functional form of the Bethe wave function while renormalizing the Bethe roots to account for integrability-breaking ...
