Is Gravity Actually the Curvature of Spacetime? [PDF]

, 2019
The Einstein equations, apart from being the classical field equations of General Relativity, are also the classical field equations of two other theories of gravity.

Integrability of classical strings dual for noncommutative gauge theories [PDF]

, 2014
We derive the gravity duals of noncommutative gauge theories from the Yang-Baxter sigma model description of the AdS_5xS^5 superstring with classical r-matrices.

Holographic chiral induced W-gravities [PDF]

, 2014
We study boundary conditions for 3-dimensional higher spin gravity that admit asymptotic symmetry algebras expected of 2-dimensional induced higher spin theories in the light cone gauge.

Holst Actions for Supergravity Theories [PDF]

, 2007
Holst action containing Immirzi parameter for pure gravity is generalised to the supergravity theories. Supergravity equations of motion are not modified by such generalisations, thus preserving supersymmetry. Dependence on the Immirzi parameter does not

Quantum Histories and Quantum Gravity

, 2009
This paper reviews the histories approach to quantum mechanics. This discussion is then applied to theories of quantum gravity. It is argued that some of the quantum histories must approximate (in a suitable sense) to classical histories, if the correct ...

Dimensionful deformations of Poincare' symmetries for a Quantum Gravity without ideal observers [PDF]

, 1998
Quantum Mechanics is revisited as the appropriate theoretical framework for the description of the outcome of experiments that rely on the use of classical devices.

Classical Symmetries of Some Two-Dimensional Models Coupled to Gravity [PDF]

, 1995
This paper is a sequel to one in which we examined the affine symmetry algebras of arbitrary classical principal chiral models and symmetric space models in two dimensions. It examines the extension of those results in the presence of gravity.

Gravity duals for logarithmic conformal field theories

, 2010
Logarithmic conformal field theories with vanishing central charge describe systems with quenched disorder, percolation or dilute self-avoiding polymers. In these theories the energy momentum tensor acquires a logarithmic partner. In this talk we address

Classical limit of quantum gravity in an accelerating universe

, 2004
A one-parameter deformation of Einstein?Hilbert gravity with an inverse Riemann curvature term is derived as the classical limit of quantum gravity compatible with an accelerating universe.
