Hamiltonians of quantum statistics and the model Hamiltonian of the theory of superconductivity
D. Ya. Petrina
Abstract:
An investigation is made of the general Hamiltonian of quantum statistics and the model
Hamiltonian of the theory of superconductivity in an infinite volume. The Hamiltonians
are given a rigorous mathematical definition as operators in a Hilbert space of sequences
of translation-invariant functions. The general Hamiltonian is not symmetric but possesses
a real spectrum; the model Hamiltonian is symmetric and its spectrum has a gap between
the energy of the ground state and the excited states.
