Scaling Behavior in 4D Simplicial Quantum Gravity
H. S. Egawa, T. Hotta, T. Izubuchi +2
Scaling relations in four-dimensional simplicial quantum gravity are proposed using the concept of the geodesic distance. Based on the analogy of a loop length distribution in the…
Geometrical Effects of Baryon Density Inhomogeneities on Primordial Nucleosynthesis
M. Orito, T. Kajino, R N. Boyd +1
We discuss effects of fluctuation geometry on primordial nucleosynthesis. For the first time we consider condensed cylinder and cylindrical-shell fluctuation geometries in addition…
Scaling Structures in Four-dimensional Simplicial Gravity
H. S. Egawa, T. Hotta, T. Izubuchi +2
Four-dimensional(4D) spacetime structures are investigated using the concept of the geodesic distance in the simplicial quantum gravity. On the analogy of the loop length distribut…
Complex structure of a DT surface with topology
H. Kawai, N. Tsuda, T. Yukawa
A method of defining the complex structure(moduli) for dynamically triangulated(DT) surfaces with torus topology is proposed. Distribution of the moduli parameter is measured numer…
2D Quantum Gravity -Three States of Surfaces-
A. Fujitsu, N. Tsuda, T. Yukawa
Two-dimensional random surfaces are studied numerically by the dynamical triangulation method. In order to generate various kinds of random surfaces, two higher derivative terms ar…
