Stochastic Gravity: Beyond Semiclassical Gravity [PDF]

, 2006
The back-reaction of a classical gravitational field interacting with quantum matter fields is described by the semiclassical Einstein equation, which has the expectation value of the quantum matter fields stress tensor as a source.

Spatially homogeneous Lifshitz black holes in five dimensional higher derivative gravity [PDF]

, 2012
We consider spatially homogeneous Lifshitz black hole solutions in five dimensional higher derivative gravity theories, which can be possible near horizon geometries of some systems that are interesting in the framework of gauge/gravity duality.

Extended Gravity Theories and the Einstein-Hilbert Action [PDF]

, 1993
I discuss the relation between arbitrarily high-order theories of gravity and scalar-tensor gravity at the level of the field equations and the action.

Microlensing, Newton-Einstein Gravity and Conformal Gravity [PDF]

, 1994
We discuss some implications of the current round of galactic dark matter searches for galactic rotation curve systematics and dynamics, and show that these new data do not invalidate the conformal gravity program of Mannheim and Kazanas which has been ...

On Classical Equivalence Between Noncritical and Einstein Gravity : The AdS/CFT Perspectives

, 2012
We find that noncritical gravity, a special class of higher derivative gravity, is classically equivalent to Einstein gravity at the full nonlinear level.

Does Yang-Mills theory describe quantum gravity? [PDF]

, 2014
The strongest version of the gauge/gravity duality conjecture relates the 1/N correction in super Yang-Mills theory and the quantum correction in superstring theory. We perform a quantitative test of this conjecture at finite temperature, by studying the

Is nonrelativistic gravity possible?

, 2009
We study nonrelativistic gravity using the Hamiltonian formalism. For the dynamics of general relativity (relativistic gravity) the formalism is well known and called the Arnowitt-Deser-Misner (ADM) formalism.

Quantum Gravity: Has Spacetime Quantum Properties? [PDF]

, 2009
The incompatibility between GR and QM is generally seen as a sufficient motivation for the development of a theory of Quantum Gravity. If - so a typical argumentation - QM gives a universally valid basis for the description of all natural systems, then ...

Gravity waves in the middle atmosphere: Recent progress and needed studies [PDF]

, 1986
The recent recognition of the important role played by gravity waves in the large-scale circulation and thermal structure of the mesosphere and lower thermosphere has stimulated considerable research on their properties and their middle atmosphere ...

Classical and Quantum Integrability of 2D Dilaton Gravities in Euclidean space

, 2004
Euclidean dilaton gravity in two dimensions is studied exploiting its representation as a complexified first order gravity model. All local classical solutions are obtained.
