Mimetic Dark Matter
Ali H. Chamseddine, Viatcheslav Mukhanov
We reformulate Einstein's theory of gravity, isolating the conformal degree of freedom in a covariant way. This is done by introducing a physical metric defined in terms of an auxi…
Who Ordered the Anti-de Sitter Tangent Group?
Ali H. Chamseddine, Viatcheslav Mukhanov
General relativity can be unambiguously formulated with Lorentz, de Sitter and anti-de Sitter tangent groups, which determine the fermionic representations. We show that besides of…
Inner Fluctuations in Noncommutative Geometry without the first order condition
Ali H. Chamseddine, Alain Connes, Walter D. van Suijlekom
We extend inner fluctuations to spectral triples that do not fulfill the first-order condition. This involves the addition of a quadratic term to the usual linear terms. We find a…
Beyond the Spectral Standard Model: Emergence of Pati-Salam Unification
Ali H. Chamseddine, Alain Connes, Walter D. van Suijlekom
The assumption that space-time is a noncommutative space formed as a product of a continuous four dimensional manifold times a finite space predicts, almost uniquely, the Standard…
Hidden Ghost in Massive gravity
Ali H. Chamseddine, Viatcheslav Mukhanov
The Hessian's determinant for a version of massive gravity given by an infinite expansion of a square root function of the induced metric, vanishes. We show that it allows us to el…
