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…

Reflection operator and hypergeometry I: spin chain

P. Antonenko, N. Belousov, S. Derkachov +1

In this work we consider open spin chain, mainly the simplest case of one particle. Eigenfunctions of the model can be constructed using the so-called reflectio…
