Revisiting the cuscuton as a Lorentz-violating gravity theory
Jishnu Bhattacharyya, Andrew Coates, Mattia Colombo +2
The cuscuton is a scalar field with infinite speed of propagation. It was introduced in the context of cosmology but it has also been claimed to resemble Horava gravity in a certai…
Gravitational Higgs Mechanism in Neutron Star Interiors
Andrew Coates, Michael W. Horbartsch, Thomas P. Sotiriou
We 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 gene…
The uninvited guest in mixed derivative Hořava Gravity
Andrew Coates, Mattia Colombo, A. Emir Gumrukcuoglu +1
We revisit the mixed derivative extension of Hořava gravity which was designed to address the naturalness problems of the standard theory in the presence of matter couplings. We co…
