Photons with half-integral spin as q-Fermions

TL;DR

This paper interprets recently discovered photons with half-integral spin as q-Fermions, which are q-deformed fermions allowing multiple particles per quantum state, and discusses their statistical properties.

Contribution

It links recent experimental findings to the theoretical framework of q-Fermions, revisiting their construction and statistical behavior from earlier work.

Findings

Photons with half-integral spin can be modeled as q-Fermions.

q-Fermions obey q-deformed anti-commutation relations.

Multiple q-Fermions can occupy the same quantum state.

Abstract

The recently discovered 'light (photons) with half-integral spin' is interpreted as q-Fermions proposed by us in 1991, as these q-Fermions satisfy q-deformed anti-commutation relations (pertaining to spin half) and have the property that more than one q-Fermion can occupy a given quantum state. In this article, in view of the recent discovery, we recall the construction of q-Fermions and give the statistical properties of q-Fermion gas, based on our preprint in 1992.
