电力Transformers的重磁模拟
Gravitatomagnetic Analogs of Electric Transformers
摘要:
线性化的广义相对论允许用重力电场和重力磁场来表述,这与麦克斯韦方程组对电磁场的描述非常相似。对于稳定的质量流,这种形式主义已经被用来理解重力磁效应,如惯性系的兰斯-瑟林拖曳。对于随时间变化的质能流,法拉第定律的模拟提出了基于Transformer的引力等效的新效应,其中这种电流取代了电流。提出了新的实验可能性,包括一种新的电磁引力耦合机制,新的测试广义相对论在超相对论极限使用粒子束在大型强子对撞机,并寻找一种材料表现出类似于铁磁性的引力。
英文摘要:
Linearized general relativity admits a formulation in terms of gravitoelectric and gravitomagnetic fields that closely parallels the description of the electromagnetic field by Maxwell's equations. For steady mass currents, this formalism has been used to understand gravitomagnetic effects like the Lense-Thirring dragging of inertial frames. For time-varying mass-energy currents, the analog of Faraday's law suggests new effects based on the gravitational equivalent of a transformer where such currents take the place of electrical currents. New experimental possibilities are suggested including a novel coupling mechanism of electromagnetism to gravity, new tests of general relativity in the ultrarelativistic limit using particle beams in the LHC, and searches for a materials exhibiting the gravitational analog of ferromagnetism.
