论文摘要

使用曲率不变性的过程来评估加速的Natario翘曲驱动器。曲率不变性独立于坐标基底座,绘制不变性的不含坐标映射失真。虽然先前的作品主要集中在翘曲气泡的数学描述上,但绘制曲率不变性为研究Natário时空及其特征提供了新的途径。对于经线驱动器空位,有四个独立的曲率不变性,RICCI标量,R_1,R_2和W_2。不变的图展示了每个曲率不变的时间如何在翘曲气泡的时间,加速度,皮肤深度和半径的参数上演变。他们表明,RICCI标量对周围时空的影响最大。他们还揭示了Natario扭曲气泡的关键特征,例如中心的平坦港口,动态唤醒以及经翘曲气泡的内部结构。

A process for using curvature invariants is applied to evaluate the accelerating Natario warp drive. Curvature invariants are independent of coordinate bases and plotting the invariants is free of coordinate mapping distortions. While previous works focus mainly on the mathematical description of the warp bubble, plotting curvature invariants provides a novel pathway to investigate the Natário spacetime and its characteristics. For warp drive spacetimes, there are four independent curvature invariants the Ricci scalar, r_1, r_2, and w_2. The invariant plots demonstrate how each curvature invariant evolves over the parameters of time, acceleration, skin depth and radius of the warp bubble. They show that the Ricci scalar has the greatest impact of the invariants on the surrounding spacetime. They also reveal key features of the Natario warp bubble such as a flat harbor in the center of it, a dynamic wake, and the internal structures of the warp bubble.
