摘要

摘要在这项工作中，我们考虑了有限温度下洛伦兹违反背景中的费米子量子气体。考虑到外部电磁场和洛伦兹违反背景场与量子费米子的相互作用，我们在路径积分形式主义中推导出有效作用。为了引入温度效应，我们采用了松原形式主义。我们还对相应的现象学进行了评论。

Fermionic quantum gas at finite temperature within a Lorentz violating background

Abstract In this work we consider a fermionic quantum gas within a Lorentz-Violating background at finite temperature. We derive the effective action within Path Integral formalism considering the interaction of external electromagnetic field and Lorentz violating background fields with quantum fermions. To introduce the temperature effects, we employ the Matsubara formalism. Comments about the corresponding phenomenology are also made.

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
