The Theoretical Landscape of Mimetic Gravity: A Comprehensive Review
O. Malaeb
Mimetic gravity has emerged as a compelling extension of General Relativity (GR), originally motivated by the attempt to isolate the conformal degree of freedom of the gravitationa…
Curvature of an Arbitrary Surface for Discrete Gravity and for Pure Simplicial Complexes
Ali H. Chamseddine, Ola Malaeb, Sara Najem
We propose a computation of curvature of arbitrary two-dimensional surfaces of three-dimensional objects, which is a contribution to discrete gravity with potential applications in…
Black Hole in Discrete Gravity
Ali H. Chamseddine, Ola Malaeb, Sara Najem
We study the metric corresponding to a three-dimensional coset space in the lattice setting. With the use of three integers , and , and a length scale,…
Curvature Tensor in Discrete Gravity
Ali H. Chamseddine, Ola Malaeb, Sara Najem
We study numerically the curvature tensor in a three-dimensional discrete space. Starting from the continuous metric of a three-sphere, we transformed it into a discrete space usin…
Scalar Curvature in Discrete Gravity
Ali H. Chamseddine, Ola Malaeb, Sara Najem
We focus on studying, numerically, the scalar curvature tensor in a two-dimensional discrete space. The continuous metric of a two-sphere is transformed into that of a lattice usin…
Mimetic Horava Gravity and Surface terms
Ola Malaeb, Chireen Saghir
We consider mimetic Horava gravity, where the scalar field of mimetic gravity was used in the construction of diffeomorphism invariant models reducing to Horava gravity in the sync…
Hamiltonian Formulation of Ghost Free Mimetic Massive Gravity
O. Malaeb, C. Saghir
We present the Hamiltonian formulation of the Ghost Free Mimetic Massive Gravity theory. The linearized theory is studied and the Hamiltonian equations of motion are analyzed. Pois…
Hamiltonian Formulation of Mimetic Gravity
O. Malaeb
The Hamiltonian formulation of Mimetic Gravity is formulated. Although there are two more equations than those of general relativity, these are proved to be the constraint equation…
Supersymmetrizing Massive Gravity
Ola Malaeb
When four scalar fields with global Lorentz symmetry are coupled to gravity and take a vacuum expectation value breaking diffeomorphism invariance spontaneously, the graviton becom…
Massive Gravity with N=1 local Supersymmetry
Ola Malaeb
A consistent theory of massive gravity, where the graviton acquires mass by spontaneously breaking diffeomorphism invariance, is now well established. We supersymmetrize this const…
