Quantum R Gravity in Two Dimensions
Two-dimensional quantum gravity with an R2 term is investigated in the continuum framework. It is shown that the partition function for small area A is highly suppressed by an exponential factor exp{−2π(1 − h)2/(m2A)}, where 1/m2 is the coefficient (times 32π) of R2 and h is the genus of the surface. Although positivity is violated, at a short distance scale ( ≪ 1/m) surfaces are smooth and the...
متن کاملScaling Dimensions of Manifestly Generally Covariant Operators in Two-Dimensional Quantum Gravity
Using (2+ǫ)-dimensional quantum gravity recently formulated by Kawai, Kitazawa and Ninomiya, we calculate the scaling dimensions of manifestly generally covariant operators in two-dimensional quantum gravity coupled to (p, q) minimal conformal matter. Although the spectrum includes all the scaling dimensions of the scaling operators in the matrix model except the boundary operators, there are a...
متن کاملScaling in quantum gravity
The 2-point function is the natural object in quantum gravity for extracting critical behavior: The exponential fall off of the 2-point function with geodesic distance determines the fractal dimension dH of space-time. The integral of the 2-point function determines the entropy exponent γ, i.e. the fractal structure related to baby universes, while the short distance behavior of the 2-point fun...
متن کاملQuantum Gravity near Apparent Horizon and Two Dimensional Dilaton Gravity
We study the Hawking radiation in two dimensional dilaton black hole by means of quantum gravity holding near the apparent horizon. First of all, we construct the canonical formalism of the dilaton gravity in two dimensions. Then the Vaidya metric corresponding to the dilaton black hole is established where it is shown that the dilaton field takes a form of the linear dilaton. Based on the cano...
متن کاملQuantum Dilaton Gravity in Two Dimensions with Fermionic Matter
Path integral quantization of generic two-dimensional dilaton gravity nonminimally coupled to a Dirac fermion is performed. After integrating out geometry exactly, perturbation theory is employed in the matter sector to derive the lowest order gravitational vertices. Consistency with the case of scalar matter is found and issues of relevance for bosonisation are pointed out. PACS numbers: 04.60...
