旋转超流体中的涡旋是否打破了弱等效原理?
Are vortices in rotating superfluids breaking the Weak Equivalence Principle?
摘要:
在旋转超流氦中,由于规范对称性破缺,涡旋的惯性质量随涡旋大小发散。因此,涡流的惯性质量远高于涡核的经典惯性质量。涡流引力质量的同等增加受到质疑。旋转超流中的涡旋可能会打破与超流真空中光速变化有关的弱等效原理,这一可能性存在争议。实验来测试这种可能性的基础上,超流氦旋涡不会下降,在一个统一的引力场的单一影响下,在相同的速度作为超流氦质量的休息。
英文摘要:
Due to the breaking of gauge symmetry in rotating superfluid Helium, the inertial mass of a vortex diverges with the vortex size. The vortex inertial mass is thus much higher than the classical inertial mass of the vortex core. An equal increase of the vortex gravitational mass is questioned. The possibility that the vortices in a rotating superfluid could break the weak equivalence principle in relation with a variable speed of light in the superfluid vacuum is debated. Experiments to test this possibility are investigated on the bases that superfluid Helium vortices would not fall, under the single influence of a uniform gravitational field, at the same rate as the rest of the superfluid Helium mass.
