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…

Introduction to Yangian in Physics
Mo-lin Ge, Kang Xue, Yiwen Wang
This is an introduction to the physical pictures of {\em Yangian} symmetry. All the discussions are based on the RTT relations which have been known to be related to the Hamiltonia…

Yangian, Truncated Yangian and Quantum Integrable Systems
Mo-lin Ge, Y. W. Wang, K. Xue
Based on the RTT relation for a given rational -matrix the {\em Yangian} and truncated {\em Yangian} are discussed. The former can be used to generate the long-range interaction…
