Apparent Lorentz violation from disformally coupled ultralight dark matter
Guillem Domènech, Apostolos Tsabodimos, Apostolos Tsampodimos +3
We study the impact of general disformal metric transformations on fermions, which shift the gravitational metric by an additional rank-2 tensor. This tensor can in principle be co…
On the consistent disformal couplings to fermions
Guillem Domènech, Alexander Ganz, Apostolos Tsabodimos +1
Disformal couplings to fermions lead to a unique derivative coupling to the axial fermionic current, which contains higher derivatives in general. We derive general conditions on c…
Finite distance effects on the Hellings-Downs curve in modified gravity
Guillem Domènech, Apostolos Tsabodimos, Apostolos Tsampodimos
There is growing interest in the overlap reduction function in pulsar timing array observations as a probe of modified gravity. However, current approximations to the Hellings-Down…
