Stability of the phonon branch of Bose spectrum of the superfluid Fermi system at large momenta
V. A. Podolskii, V. N. Popov
Abstract:
The phonon branch of Bose spectrum of superfluid Fermi system (Bogoliubov sound) is (investigated at $T=0$ It is shown, that every Bogoliubov sound quant (with arbitrary momentum) is stable and can not decay in several exitations with lower energy.
