量子引力的Lorentz破坏

Lorentz Violation of Quantum Gravity

J. W. Moffat

摘要:

研究了一个量子引力理论,该理论由于洛伦兹不变性和自同态不变性的自发对称性破缺而在短距离下可重整化。提出了洛仑兹不变性的破缺,破缺模式分别为3+1和2+1量子引力的破缺模式$SO(3,1)\to O(3)$和$SO(3,1)\to O(2)$.在普朗克能量下的自发破缺对称相和早期宇宙中存在着一个复杂的依赖于时间的薛定谔方程(广义惠勒-德威特方程),它将量子力学和广义相对论结合在一起。在引力对称破缺阶段可以解释热力学第二定律和早期宇宙中物质的自发创生。

英文摘要:

A quantum gravity theory which becomes renormalizable at short distances due to a spontaneous symmetry breaking of Lorentz invariance and diffeomorphism invariance is studied. A breaking of Lorentz invariance with the breaking patterns $SO(3,1)\to O(3)$ and $SO(3,1)\to O(2)$, describing 3+1 and 2+1 quantum gravity, respectively, is proposed. A complex time dependent Schrödinger equation (generalized Wheeler-DeWitt equation) for the wave function of the universe exists in the spontaneously broken symmetry phase at Planck energy and in the early universe, uniting quantum mechanics and general relativity. An explanation of the second law of thermodynamics and the spontaneous creation of matter in the early universe can be obtained in the symmetry broken phase of gravity.
