# Equation of State of Quantum Gases Beyond the Van der Waals Approximation

@article{Bugaev2018EquationOS, title={Equation of State of Quantum Gases Beyond the Van der Waals Approximation}, author={Kyrill A. Bugaev and A. I. Ivanytskyi and Violetta Sagun and Eduard G. Nikonov and Gennady Zinovjev}, journal={Ukrainian Journal of Physics}, year={2018} }

A recently suggested equation of state with the induced surface tension is generalized to the case of quantum gases with mean-field interaction. The self-consistency conditions of such a model and the conditions necessary for the Third Law of thermodynamics to be satisfied are found. The quantum virial expansion of the van der Waals models of such a type is analyzed, and its virial coefficients are given. In contrast to traditional beliefs, it is shown that an inclusion of the third and higherβ¦Β
