Critical points in a relativistic bosonic gas induced by the quantum structure of spacetime

TL;DR

This paper demonstrates that quantum gravity-induced spacetime structure can lead to critical points in a relativistic bosonic gas without particle interactions, highlighting a novel link between quantum gravity and phase transition phenomena.

Contribution

It reveals that Lorentz symmetry breaking and bosonic statistics alone can induce critical points, a new insight into quantum gravity effects on many-body systems.

Findings

Critical points can emerge without particle interactions.

Spacetime structure influences phase transition behavior.

Lorentz symmetry breaking affects thermodynamic properties.

Abstract

It is well known that phase transitions arise if the interaction among particles embodies an attractive as well as a repulsive contribution. In this work it will be shown that the breakdown of Lorentz symmetry, characterized through a deformation in the relation dispersion, plus the bosonic statistics predict the emergence of critical points. In other words, in some quantum gravity models the structure of spacetime implies the emergence of critical points even when no interaction among the particle has been considered.
