The Generalized Lipkin-Meshkov-Glick Model and the Modified Algebraic Bethe Ansatz

We show that the Lipkin-Meshkov-Glick 2𝑁-fermion model is a particular case of a one-spin Gaudin-type model in an external magnetic field corresponding to a limiting case of a non-skew-symmetric elliptic 𝑟-matrix and to an external magnetic field directed along one axis. We propose an exactly-solvab...
