Bogoliubov Hamiltonians and one parameter groups of Bogoliubov transformations
L. Bruneau, J. Derezinski
On the bosonic Fock space, a family of Bogoliubov transformations corresponding to a strongly continuous one-parameter group of symplectic maps R(t) is considered. Under suitable a…

On the infimum of the energy-momentum spectrum of a homogeneous Bose gas
H. D. Cornean, J. Dereziński, P. Ziń
We consider second quantized homogeneous Bose gas in a large cubic box with periodic boundary conditions, at zero temperature. We discuss the energy-momentum spectrum of the Bose g…
