Nested Bethe ansatz for spin chains

Ragoucy, E (LAPTH (CNRS))
Monday 23 March 2009, 16:30-17:30

Seminar Room 1, Newton Institute


We present in a unified way the nested Bethe ansatz for spin chains based on gl(n), gl(m|n) and their deformations. We perform the ansatz for closed and open spin chains. In the case of open spin chains, we use diagonal boundary conditions. In all cases, we deduce a recursion formula, and a trace formula for Bethe vectors.
