Observing 4 d baby universes in quantum gravity
We measure the fractal structure of four dimensional simplicial quantum gravity by identifying so-called baby universes. This allows an easy determination of the critical exponent γ connected to the entropy of four-dimensional manifolds.
متن کاملBaby Universes in 2d Quantum Gravity
We investigate the fractal structure of 2d quantum gravity, both for pure gravity and for gravity coupled to multiple gaussian fields and for gravity coupled to Ising spins. The roughness of the surfaces is described in terms of baby universes and using numerical simulations we measure their distribution which is related to the string susceptibility exponent γstring.
متن کاملScaling Functions for Baby Universes in Two-Dimensional Quantum Gravity
We apply the recently proposed transfer matrix formalism to 2-dimensional quantum gravity coupled to (2, 2k − 1) minimal models. We find that the propagation of a parent universe in geodesic (Euclidean) time is accompanied by continual emission of baby universes and derive a distribution function describing their sizes. The k → ∞ (c → −∞) limit is generally thought to correspond to classical ge...
متن کاملQuantum Entanglement of Baby Universes
We study quantum entanglements of baby universes which appear in non-perturbative corrections to the OSV formula for the entropy of extremal black holes in Type IIA string theory compactified on the local Calabi-Yau manifold defined as a rank 2 vector bundle over an arbitrary genus G Riemann surface. This generalizes the result for G = 1 in hep-th/0504221. Non-perturbative terms can be organize...
متن کاملWorld-Sheet Geometry and Baby Universes in 2-D Quantum Gravity
We show that the surface roughness for c < 1 matter theories coupled to 2D quantum gravity is described by a self-similar structure of baby universes. There exist baby universes whose neck thickness is of the order of the ultraviolet cutoff, the largest of these having a macroscopic area ∼ A 1 1−γ , where A is the total area and γ the string susceptibility exponent.
