TL;DR
This paper investigates the finite temperature behavior of a Lorentz-breaking term in extended QED, revealing that its ambiguities persist from zero to finite temperature, impacting theoretical consistency.
Contribution
It demonstrates that the ambiguities of the CPT-even aether-like Lorentz-breaking term remain at finite temperature, extending previous zero-temperature findings.
Findings
Ambiguities persist at finite temperature.
The Lorentz-breaking term's behavior is temperature-independent.
Implications for the consistency of Lorentz-violating theories.
Abstract
In this paper, we consider the finite temperature behaviour of the CPT-even aether-like Lorentz-breaking term in the extended Lorentz-breaking QED and demonstrate that its ambiguities whose presence has been shown earlier in the zero temperature case stay also at the finite temperature.
