Abstract:
If in the usual formulation of the method of quasiaverages one uses “sources” of
special type corresponding to the symmetry of the considered geometric structure, it is possible to show that spatial ordering arises in the model of a quantum crystal. With allowance for macroscopic filling of the states corresponding to the distinguished symmetry, a calculation is made of an excitation spectrum in which there exists a collective branch of gapless type.
