A Unified Treatment for XXX-Heisenberg Model and Haldane-Shastry Model Using Shift Operators
Jing-Ling Chen, Mo-Lin Ge, Kang Xue +1
A unified treatment is developed for the XXX-Heisenberg model and a long-ranged interaction model (the in Haldane-Shastry model) from the point of view of shift operators (or…

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