*"**Structure of the excitation spectrum for many-body quantum systems"*
**
/_Abstract:_////Many questions concerning models in quantum mechanics
require a detailed analysis of the spectrum of the corresponding
Hamiltonian, a linear operator on a suitable Hilbert space.
Of particular relevance for an understanding of the low-temperature
properties of a system is the structure of the excitation spectrum,
which is the part of the spectrum close to the spectral bottom.
We present recent progress on this question for bosonic many-body
quantum systems with weak two-body interactions. Such system are
currently of great interest, due to their experimental realization
in ultra-cold atomic gases. We investigate the accuracy of the
Bogoliubov approximations, which predicts that the low-energy spectrum
is made up of sums of elementary excitations,
with linear dispersion law at low momentum. The latter property is
crucial for the superfluid behavior the system.///
