由真空产生粒子的洛伦兹破坏

Particle Creation from Vacuum by Lorentz Violation

Nima Khosravi

摘要:

结果表明,真空状态下存在的洛伦兹破坏可以遵循一个粒子充满宇宙,代表了目前的宇宙状态。在这个模型中,色散关系的修正(洛伦兹破坏)被提取出来,代表了量子引力的状态。这个结果可以被解释为粒子的存在是过去引力的量子效应的证据。经过半经典分析,得出只有真空态才足以使物质场自发出现的结论。

英文摘要:

It is shown that the vacuum state in presence of Lorentz violation can be followed by a particle-full universe that represents the current status of the universe. In this model the modification in dispersion relation (Lorentz violation) is picked up representing the regime of quantum gravity. The result can be interpreted such that the existence of the particles is an evidence for quantum effects of gravity in the past. It is concluded that only the vacuum state is sufficient to appear the matter fields spontaneously after the process of semi-classical analysis.
