Exactly solvable gl(m/n) Bose-Fermi systems
Abstract
A simple SUSY Bose-Fermi Hamiltonian and a class of hard-core Bose-Fermi Hamiltonians with high order terms constructed by using the gl(m/n) generators are shown to be exactly solvable. Excitation energies and corresponding wavefunctions are obtained by using a simple algebraic Bethe ansatz.
