Algebraic Geometry Approach to the Bethe Equation for Hofstadter Type Models
Shao-shiung Lin, Shi-shyr Roan
We study the diagonalization problem of certain Hofstadter-type models through the algebraic Bethe ansatz equation by the algebraic geometry method. When the spectral variables lie…

Bethe Ansatz for Heisenberg XXX Model
Shao-shiung Lin, Shi-shyr Roan
We investigate Bethe Ansatz equations for the one-dimensional spin- Heisenberg XXX chain with a special interest in a finite system. Solutions for the two-particle sec…
