Bose-like few-fermion systems

TL;DR

This paper investigates how small fermion systems behave differently depending on whether they have even or odd numbers of particles, revealing that even-numbered systems mimic Bose systems more than Fermi systems.

Contribution

It demonstrates the distinct behavior of few-fermion systems in the canonical ensemble, highlighting the Bose-like nature of even-numbered systems.

Findings

Even-number-fermion systems behave like Bose systems.

Odd-number-fermion systems exhibit different fermionic behavior.

Canonical ensemble analysis reveals these differences.

Abstract

Dealing with a few-fermion system in the canonical ensemble, rather than in the grand canonical ensemble, shows that a few-fermion system with odd number fermions behaves differently from a few-fermion system with even number fermions. An even-number-fermion system behaves like a Bose system rather than a Fermi system.
