Shift Operators for XXX-Heisenberg Chain
Jing-Ling Chen, Mo-Lin Ge, Kang Xue
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.
