自由降落中的潮汐和非平衡Casimir效应
Tidal and nonequilibrium Casimir effects in free fall
摘要：
在这项工作中，我们考虑了一个卡西米尔装置，该装置被置于自由降落（例如，落入黑洞）。在1+1D中工作，我们发现发生了两个主要效应：第一，Casimir能量密度经历了潮汐效应，负能量被推向板块，板块所经历的合力增加。第二，下落的过程本质上是非平衡的，我们也这样对待它，证明了卡西米尔能量密度在“下落”后在两块板之间来回移动，力的调制是同步的。这样，卡西米尔能量的行为就像经典液体一样，当它在容器中移动时，会在壁上施加（负）压力。特别是，我们认为这是在一个黑洞和多重真空，可以实现外部的设备。
英文摘要：
In this work, we consider a Casimir apparatus that is put into free fall (e.g., falling into a black hole). Working in 1+1D, we find that two main effects occur: First, the Casimir energy density experiences a tidal effect where negative energy is pushed toward the plates and the resulting force experienced by the plates is increased. Second, the process of falling is inherently nonequilibrium and we treat it as such, demonstrating that the Casimir energy density moves back and forth between the plates after being "dropped,'' with the force modulating in synchrony. In this way, the Casimir energy behaves as a classical liquid might, putting (negative) pressure on the walls as it moves about in its container. In particular, we consider this in the context of a black hole and the multiple vacua that can be achieved outside of the apparatus.
