Based on the representation of collective variables with the Hermitian form of the Bogolyubov–Zubarev Hamiltonian, a self-consistent oscillator model of the ground state and excited states of a Bose liquid has been proposed. A new method of calculation of anharmonic terms in this Hamiltonian and its...
