ON THE NO-GRAVITY LIMIT OF GRAVITY [PDF]
The Thirteenth Marcel Grossmann Meeting, 2015 We argue that Relative Locality may arise in the no gravity $G\rightarrow0$ limit of gravity. In this limit gravity becomes a topological field theory of the BF type that, after coupling to particles, may effectively deform its dynamics. We briefly discuss another no gravity limit with a self dual ground state as well as the topological ultra strong $G\

Gravity, dual gravity and A1+++ [PDF]
International Journal of Modern Physics A, 2020 We construct the nonlinear realisation of the semidirect product of the very extended algebra [Formula: see text] and its vector representation. This theory has an infinite number of fields that depend on a space–time with an infinite number of coordinates.

Einstein gravity from Conformal Gravity in 6D [PDF]
Journal of High Energy Physics, 2021 Abstract We extend Maldacena’s argument, namely, obtaining Einstein gravity from Conformal Gravity, to six dimensional manifolds. The proof relies on a particular combination of conformal (and topological) invariants, which makes manifest the fact that 6D Conformal Gravity admits an Einstein sector.

Gravity as entanglement, entanglement as gravity [PDF]
SSRN Electronic Journal, 2020 A generalized and unifying viewpoint to both general relativity and quantum mechanics and information is investigated. It may be described as a generaliztion of the concept of reference frame from mechanics to thermodynamics, or from a reference frame linked to an element of a system, and thus, within it, to another reference frame linked to the whole ...

Symmetry, 2022 We review and discuss some recent developments on the unconventional interaction between superconducting systems and the local gravitational field. While it is known that gravitational perturbations (such as gravitational waves) can affect supercondensates and supercurrents dynamics, we want to focus here on the more subtle superfluid back-reaction ...

On quantum gravity and quantum gravity phenomenology
The Sixteenth Marcel Grossmann Meeting, 2023 This article summarizes a new approach to quantum gravity based on the concepts of modular spacetime, Born geometry, and metastring theory and their applications to quantum gravity phenomenology. In particular, we discuss a new understanding of dark matter in terms of metaparticles (zero modes of the metastring) and its relation to dark energy (the ...

GRAVITY AND MIRROR GRAVITY IN PLEBANSKI FORMULATION [PDF]
International Journal of Modern Physics A, 2013 We present several theories of four-dimensional gravity in the Plebanski formulation, in which the tetrads and the connections are the independent dynamical variables. We consider the relation between different versions of gravitational theories: Einsteinian, "topological," "mirror" gravities and gravity with torsion.
