BC-type open spin chain
P. Antonenko, S. Derkachov, P. Valinevich
We diagonalize the -element of monodromy matrix for noncompact open spin chain with boundary interaction. The monodromy matrix is defined in terms of $SL(2,\m…

Reflection operator and hypergeometry II: spin chain
P. Antonenko, N. Belousov, S. Derkachov +1
We consider noncompact open spin chain and construct eigenfunctions of -element of monodromy matrix for the simplest case of the chain with one site. The ref…
