隧道效应与能量条件的动力学破坏

Tunnelling and dynamical violation of the Null Energy Condition

Jean Alexandre, Janos Polonyi

摘要:

能量条件被认为是能量条件中最基本的条件,几个关键的结果,如奇异性定理,都是基于能量条件。卡西米尔效应是罕见的平衡机制之一,通过这种机制,它被打破,而不需要调用修改的引力或与奇异物质的非最小耦合。在这项工作中,我们提出了一个独立的动力学机制,它被违反,与唯一的成分是标准的(但非微扰)QFT和最低限度的耦合标量场在双阱势。至于Casimir效应,我们解释了为什么平均能量条件不应该被这种机制所破坏。然而,这种短暂的行为可能对早期宇宙学产生深远的影响。

英文摘要:

The Null Energy Condition is considered the most fundamental of the energy conditions, on which several key results, such as the singularity theorems, are based. The Casimir effect is one of the rare equilibrium mechanisms by which it is breached without invoking modified gravity or non-minimal couplings to exotic matter. In this work we propose an independent dynamical mechanism by which it is violated, with the only ingredients being standard (but non-perturbative) QFT and a minimally coupled scalar field in a double-well potential. As for the Casimir effect, we explain why the Averaged Null Energy Condition should not be violated by this mechanism. Nevertheless, the transient behaviour could have profound impacts in Early Universe Cosmology.
