Exact diagonalization of the truncated Bogoliubov Hamiltonian
Abstract
The present short note is simply intended to communicate that I have analytically diagonalized the Bogoliubov truncated Hamiltonian Hc~Bogo1,Bogo2, in an interacting bosonic gas. This is the natural prosecution of my work~MS, now denoted as (I), where the diagonalization was performed only in the subspace corresponding to zero momentum collective excitations (CE).
