Bose Gas in Classical Environment at Low Temperatures

https://doi.org/10.15407/ujpe65.11.1002Keywords:
dilute Bose gas, weak non-Gaussian disorder, superfluid propertiesAbstract
The properties of a dilute Bose gas with the non-Gaussian quenched disorder are analyzed. Being more specific, we have considered a system of bosons immersed in the classical bath consisting of the non-interacting particles with infinite mass. Making use of perturbation theory up to the second order, we have studied the impact of environment on the ground-state thermodynamic and superfluid characteristics of the Bose component.
