Orest Hryhorchak, Volodymyr Pastukhov
TL;DR
This paper investigates the thermodynamic properties of a non-ideal Bose gas with many components, focusing on how interactions affect condensate depletion and compressibility at large N.
Contribution
It provides a numerical analysis of large-N corrections to Bose-Einstein condensate depletion and compressibility in a non-ideal Bose gas with symmetrical interactions.
Findings
Large-N corrections influence condensate depletion
Compressibility shows significant dependence on interaction strength
Numerical results clarify thermodynamic behavior at high N
Abstract
We rigorously discuss the large- thermodynamics of a Bose gas with a short-range two-body potential. Considering the system as a mixture of identical components with symmetrical interaction we calculated numerically the temperature dependence of the leading-order corrections to the depletion of Bose-Einstein condensate and to the isothermal compressibility.
