均匀磁场和非零温度对QED中显式手征对称性破缺的影响:任意能级

Alejandro Ayala, Adnan Bashir, Alfredo Raya, Angel Sanchez

摘要:

利用Schwinger的本征时间方法,计算了热浴中重Dirac费米子与均匀磁场相互作用的$e$凝聚。我们提出的一般结果,任意层次的能量尺度,即费米子质量$m$,磁场强度$\sqrt{eB}$和温度$T$。此外,我们详细研究特定的制度,并重现一些计算或预期的结果在文献中。我们还讨论了我们的研究结果的可能应用。

英文摘要:

Employing the Schwinger's proper-time method, we calculate the $<\barψ ψ>$-condensate for massive Dirac fermions of charge $e$ interacting with a uniform magnetic field in a heat bath. We present general results for arbitrary hierarchy of the energy scales involved, namely, the fermion mass $m$, the magnetic field strength $\sqrt{eB}$ and temperature $T$. Moreover, we study particular regimes in detail and reproduce some of the results calculated or anticipated earlier in the literature. We also discuss possible applications of our findings.
