Generalized Kappa Distribution Function for Mixed Fermiom-Boson Quantum Plasmas

Plasma Physics 2025-05-19 v1 Space Physics

Abstract

A Kappa distribution function applicable to systems comprising mixed fermions and bosons has been developed through the thermodynamic Gibbs potential utilizing the quantum versions of the Olbert kappa distributions. The generalised expressions of the partition function and the entropy have been evaluated for such mixed quantum systems. The analysis shows that boson-rich systems consistently exhibit higher entropy than fermion-rich systems. The distribution functions show heavy-tailed characteristics at low Kappa values, indicating the presence of superthermal particles. It is observed that relativistic effects lead to a significant increase in entropy.
