洛伦兹破缺理论与Vaidya黑洞弯曲时空中的Dirac粒子隧穿辐射特征

论文摘要

本文把平直时空中的洛伦兹对称性破缺的Dirac方程推广到动态Vaidya黑洞弯曲时空中.由于动态Vaidya黑洞的表观视界与类时极限面重合,根据霍金辐射量子效应理论,我们在Vaidya黑洞的表观视界ra=2M（v）处研究了洛伦兹破缺理论对Dirac粒子Hawking隧穿辐射特征的影响.我们通过gamma矩阵的对易性质和半经典近似得到了一个新的洛伦兹对称性破缺的Dirac-Hamilton-Jacobi方程,并利用这一修正的Dirac-Hamilton-Jacobi方程研究了Dirac粒子隧穿辐射的特征,讨论了洛伦兹对称性破缺对动态球对称Vaidya黑洞的热力学参数的影响.结果发现,洛伦兹破缺理论中仅有类以太修正项会对黑洞热力学性质带来修正.同时,还发现修正Hawking温度与类以太矢量修正项系数的正负有关,而我们之前应用洛伦兹破缺理论研究标量粒子的修正Hawking温度也是与类以太矢量修正项系数的正负有关的.
