论文摘要

最近,引入了一个玩具模型,以证明替代性重力理论中的筛查机制可以隐藏其他效果。在此型号中,标量字段由$ u(1)$对称性收取。在足够紧凑的对象中,标量场会自发生长,即对象标记,自发打破$ u(1)$对称性。与$ u(1)$ higgs机制一样,这导致了量规场的出现。 本文的目的是提供一个示例,如果我们将这种玩具模型视为违规的弱等价原理(WEP)的原型,则可以提供物理后果。我们用偶极磁场对中子恒星进行建模,以比较一方面的爱因斯坦 - 马克斯韦理论中恒星的磁场行为,并在标量探测理论中与所谓的,引力的Higgs机制相比。

Recently, a toy model was introduced to demonstrate that screening mechanisms in alternative theories of gravitation can hide additional effects. In this model a scalar field is charged under a $U(1)$ symmetry. In sufficiently compact objects the scalar field spontaneously grows, i.e. the object scalarizes, spontaneously breaking the $U(1)$ symmetry. Exactly as in the $U(1)$ Higgs mechanism this leads to the emergence of a mass for the gauge field. The aim of this paper is to provide an example of the physical consequences if we consider this toy model as a prototype of Weak Equivalence Principle (WEP) violations. We model neutron stars with a dipolar magnetic field to compare the magnetic field behaviour of stars in Einstein-Maxwell theory on the one hand and in scalar-tensor theory with the, so-called, gravitational Higgs mechanism on the other hand.
