Effective field theory reproducing the MOND phenomenology based on a non-Abelian Yang-Mills graviphoton
Luc Blanchet, Emeric Seraille
Motivated by the phenomenology of MOND, we propose a theory based on a fundamental non Abelian Yang-Mills gauge field with gravitational coupling constant (a "graviphoton") emergin…
Dipolar dark matter theory based on a non-Abelian Yang-Mills field
Luc Blanchet, Emeric Seraille
Most theories that attempt to reproduce the Modified Newtonian Dynamics (MOND) phenomenology for dark matter at galactic scales rely on ad hoc free functions, preventing them from…
Khronon-Tensor theory reproducing MOND and the cosmological model
Luc Blanchet, Constantinos Skordis
We propose an alternative scalar-tensor theory based on the Khronon scalar field labeling a family of space-like three-dimensional hypersurfaces. This theory leads to modified Newt…
Gravitational radiation reaction for compact binary systems at the fourth-and-a-half post-Newtonian order
Luc Blanchet, Guillaume Faye, David Trestini
We compute the gravitational radiation-reaction force on a compact binary source at the fourth-and-a-half post-Newtonian (4.5PN) order of general relativity, i.e., 2PN order beyond…
Relativistic Khronon Theory in agreement with Modified Newtonian Dynamics and Large-Scale Cosmology
Luc Blanchet, Constantinos Skordis
We propose an extension of General Relativity (GR) based on a space-time foliation by three-dimensional space-like hypersurfaces labeled by the Khronon scalar field . We show t…
