Gravitational Higgs mechanism in neutron star interiorsTools Coates, Andrew and Horbatsch, Michael W. and Sotiriou, Thomas P. (2017) Gravitational Higgs mechanism in neutron star interiors. Physical Review D, 95 (8). 084003/1-084003/6. ISSN 2470-0029 Full text not available from this repository.AbstractWe suggest that nonminimally coupled scalar fields can lead to modifications of the microphysics in the interiors of relativistic stars. As a concrete example, we consider the generation of a non-zero photon mass in such high-density environments. This is achieved by means of a light gravitational scalar, and the scalarization phase transition in scalar-tensor theories of gravitation. Two distinct models are presented, and phenomenological implications are briefly discussed.
