Title: Density matrix of the system of identical particles,
interacting via oscillator forces
Authors: I.O. Vakarchuk
The exact expression for N-particles density matrix is obtained for
D-dimensional system of identical particles, connected by
oscillator forces.
This expression is presented as a product of the ideal gas
density matrix with the
renormalized mass and a factor, which does not depend on statistics
and depicts only the character of interparticle interaction.
