旋量耦合到三维引力的弱Poincare规范理论

Spinor coupling to the weak Poincare gauge theory of gravity in three dimensions

Özcan Sert, Muzaffer Adak

摘要:

在(1+2)维空间中考虑了具有最一般非传播挠率的狄拉克场与引力的最小耦合。场方程由拉格朗日量通过变分原理得到。时空挠率的代数计算的二次旋量凝聚体加上耦合系数。首先,我们给出了在没有Dirac凝聚的情况下坍缩到$AdS_3$几何的圆对称旋转精确解。其次,我们研究了一个类BTZ的解决方案。

英文摘要:

Minimal coupling of a Dirac field to gravity with the most general non-propagating torsion is considered in (1+2)-dimensions. The field equations are obtained from a lagrangian by a variational principle. The space-time torsion is calculated algebraically in terms of a quadratic spinor condensate plus coupling coefficients. Firstly we give circularly symmetric rotating exact solutions that collapse to $AdS_3$ geometry in the absence of the Dirac condensate. Secondly we investigate a BTZ-like solution.
