Exactly soluble model of interacting electrons |
| Date |
1972 |
| Description |
We diagonalize a many-fermion Hamiltonian consisting of terms quadratic as well as quartic in the field operators. A dual spectrum of eigenstates is an interesting result. We also derive a formula for obtaining the free energy at finite temperature. |
