Exact ground state for a class of matrix Hamiltonian models: quantum phase transition and universality in the thermodynamic limit

Massimo Ostilli, Carlo Presilla

By using a recently proposed probabilistic approach, we determine the exact ground state of a class of matrix Hamiltonian models characterized by the fact that in the thermodynamic…
