Quantum Corrections to the Two Dimensional Gravity with External Field
نویسنده
چکیده
We introduce an external field to calculate the quantum corrections to the solutions of the 2d gravity, via trace anomaly. We show that there are black hole type solutions even in the absence of matter field and cosmological constant. We also see that these solutions are similar to the ones obtained from dilaton two dimensional gravity.

Quantum gravitational corrections to black hole geometries
We calculate perturbative quantum gravity corrections to generic eternal two-dimensional dilaton gravity spacetimes. We estimate the leading corrections to the AdS2 black hole entropy and determine the quantum modification of N -dimensional Schwarzschild spacetime. ∗ [email protected] † [email protected] In recent years, two-dimensional dilaton gravity has earned a great deal of attentio...
متن کاملConformal Dimensions from Topologically Massive Quantum Field Theory
We discuss the evaluation of observables in two-dimensional conformal field theory using the topological membrane description. We show that the spectrum of anomalous dimensions can be obtained perturbatively from the topologically massive quantum field theories by computing radiative corrections to Aharonov-Bohm scattering amplitudes for dynamical charged matter fields. The one-loop corrections...
متن کاملSpherically Symmetric Solutions in a New Braneworld Massive Gravity Theory
In this paper, a combination of the braneworld scenario and covariant de Rham-Gabadadze-Tolley (dRGT) massive Gravity theory is proposed. In this setup, the five-dimensional bulk graviton is considered to be massive. The five dimensional nonlinear ghost-free massive gravity theory affects the 3-brane dynamics and the gravitational potential on the brane. Following the solutions with spherical s...
متن کاملHigher Curvature Gravity: Entropy Bound and Causality Violation
In any quantum theory of gravity we do expect corrections to Einstein gravity to occur. Yet, at fundamental level, it is not apparent what the most relevant corrections are. We argue that the generic curvature square corrections present in lower dimensional actions of various compactified string theories provide a natural passage between the classical and quantum realms of gravity. The Gauss-Bo...
متن کاملThe leading quantum corrections
I describe the treatment of gravity as a quantum effective field theory. This allows a natural separation of the (known) low energy quantum effects from the (unknown) high energy contributions. Within this framework, gravity is a well behaved quantum field theory at ordinary energies. In studying the class of quantum corrections at low energy, the dominant effects at large distance can be isola...
