A model Hamiltonian of the BCS type for a Bose gas
V. P. Yatsishin
Abstract:
A study is made of a model Hamiltonian of BCS type for a Bose gas and it is given a rigorous
mathematieal meaning tn the ease of an infinite volume. The grand partition function is calculated
and an equation of state is found, it is shown that in the ease of an infinite volume the
chain of equations for the Green's functions has two solutions: free Green's funetions and
Green's functions of the approximating Hamittonian.
