Shift Operators for XXX-Heisenberg Chain

arXiv:cond-mat/9810131

Abstract

The shift operators for XXX-Heisenberg chain are found. They are formed by local Yangian operators and the amplitutes of the eigenfunctions obeying Bethe ansatz for the Hamiltonian. The physical implication of the shift operators are also explained.
