Collective excitations and superfluid properties of a two-dimensional interacting Bose gas in an external potential
We develop an approach for a description of collective excitations in a two-dimensional gas of interacting Bose particles in an external potential. We present a method of finding an approximate analytical solution for the spectra of collective excitations of a Bose gas in a linear potential and in a...
