Quantum gravity stability of isotropy in homogeneous cosmology
quantum stability cosmological isotropy cosmological
2011/10/17
It has been shown that anisotropy of homogeneous spacetime described by the general Kasner metric can be damped by quantum fluctuations coming from perturbative quantum gravity in one-loop approximati...
Black holes in an ultraviolet complete quantum gravity
Black holes ultraviolet complete quantum gravity
2011/1/13
In this Letter we derive the gravity field equations by varying the action for an ultraviolet complete quantum gravity. Then we consider the case of a static source term and we determine an exact bla...
Ghost anomalous dimension in asymptotically safe quantum gravity
ghost anomalous dimension quantum gravity
2010/3/22
We compute the ghost anomalous dimension within the asymptotic-safety scenario for quantum gravity. For a class of covariant gauge fixings and using a functional RG scheme, the anomalous dimension $\e...
The Generalized Uncertainty Principle and Quantum Gravity Phenomenology
Quantum Gravity Phenomenology
2010/3/19
In this article we examine a Generalized Uncertainty Principle which differs from the Heisenberg Uncertainty Principle by terms linear and quadratic in particle momenta, as proposed by the authors in ...
