论文摘要
在这项工作中,我们分析了由于存在量子物质而导致的翘曲时空发展潜力的潜力。特别是,我们寻找无限的蓝光点(类似于黑洞内部地平线的点,以其半经典不稳定性而闻名),并通过在其附近的地理学行为对其进行分类。我们发现,在尺寸2+1或更高的扭曲驱动气泡实际上很可能是稳定的,因为它们通常仅包含接近差异的孤立点,从而导致了不稳定能量的整体积累的有限限制。此外,由于能量密度堆积而引起的经纱驱动器中的任何半经典不稳定性都可以通过特殊的``空气动力学形状''和驱动器的轨迹进一步减少。
In this work we analyse the potential for a warp drive spacetime to develop instabilities due to the presence of quantum matter. Particularly, we look for points of infinite blueshift (which are analogous to points of a black hole inner horizon, known for its semiclassical instability), and categorise them through the behaviour of geodesics in their vicinity. We find that warp-drive bubbles in dimension 2+1 or higher are in fact likely to be stable, as they generally contain only isolated points where divergences are approached, leading to a finite limit for the overall accumulation of destabilising energy. Furthermore, any semiclassical instabilities in the warp drive due to energy-density buildups can be further diminished with particular, more ``aerodynamic" shapes and trajectories for the drive.
