Quantum corrections and multioccupancy in a semi-classical gas

Quantum Physics [Submitted on 21 Mar 2026] Quantum corrections and multioccupancy in a semi-classical gas Loris Ferrari The quantum corrections to the behavior of a semi-classical gas can be expressed as a power series of the ratio eta between the cube of De Broglie's thermal wavelength and the specific volume. The connection between eta and the multioccupancy of quantum states is the aim of the present work. By means of a chemical/physical approach it is possible to associate eta to the concrete realization of multioccupancy in momentum space, through the formation of what we call "pseudo-molecules", i.e. multiplets of particles sharing momenta whose differences are negligeable in the continuous spctrum approximation. The pseudo-molecules result as casual consequences of multiple scattering processes among non interacting (scattering apart) particles.
