Holography and Emergent 4D Gravity

نویسنده

  • Francesco Nitti
چکیده

I review recent work toward constructing, via five-dimensional holographic duals, fourdimensional theories in which spin-2 states (gravitons) are emergent. The basic idea is to extend to gravity model-building the applications of holographic duality to phenomenology construction.

Strong Coupling Holography

We show that whenever a 4-dimensional theory with N particle species emerges as a consistent low energy description of a 3-brane embedded in an asymptotically-flat (4 + d)-dimensional space, the holographic scale of high-dimensional gravity sets the strong coupling scale of the 4D theory. This connection persists in the limit in which gravity can be consistently decoupled. We demonstrate this e...

A Holographic Dual of CFT with Flavor on de Sitter Space

We introduce a D7-brane probe in AdS5×S background in a way that the 4d part of the induced metric on D7-brane becomes 4d de-Sitter space (dS4) inside AdS5 instead of 4d Minkowski space. Although supersymmetry is completely broken, we obtain a static configuration and show the absence of dynamical tachyonic modes. Following holographic renormalization we renormalize the Dirac-Born-Infeld action...

Conformal Gravity, Maxwell and Yang-Mills Unification in 4D from a Clifford Gauge Field Theory

A model of Emergent Gravity with the observed Cosmological Constant from a BF-Chern-Simons-Higgs Model is revisited which allows to show how a Conformal Gravity, Maxwell and SU(2) × SU(2) × U(1) × U(1) Yang-Mills Unification model in four dimensions can be attained from a Clifford Gauge Field Theory in a very natural and geometric fashion.

Emergence in Holographic Scenarios for Gravity

‘Holographic’ relations between theories have become an important theme in quantum gravity research. These relations entail that a theory without gravity is equivalent to a gravitational theory with an extra spatial dimension. The idea of holography was first proposed in 1993 by Gerard ’t Hooft on the basis of his studies of evaporating black holes. Soon afterwards the holographic ‘AdS/CFT’ dua...

Equipartition of Microscopic Degrees of Freedom, Space–time Entropy and Holography∗

One can identify the number density of the microscopic space–time degrees of freedom in any diffeomorphism-invariant theory of gravity by using the principle of equipartition, applied to the area elements of a surface ∂V which are at the local Unruh temperature. The entropy associated with these degrees of freedom, which matches with the Wald entropy for the theory, can be used to obtain the fi...
