The half-infinite XXZ chain in Onsager's approach    [PDF]

P. Baseilhac, S. Belliard
The half-infinite XXZ open spin chain with general integrable boundary conditions is considered within the recently developed `Onsager's approach'. Inspired by the finite size case, the transfer matrix is simply expressed in terms of the elements of a new type of current algebra recently introduced. In the massive regime $-1
