The Spectral Dimension of Non-generic Branched Polymer Ensembles

(1997)

Authors:

Joao D Correia, John F Wheater

The spectral dimension of the branched polymers phase of two-dimensional quantum gravity

ArXiv hep-lat/9710024 (1997)

Authors:

Thordur Jonsson, John F Wheater

Abstract:

The metric of two-dimensional quantum gravity interacting with conformal matter is believed to collapse to a branched polymer metric when the central charge c>1. We show analytically that the spectral dimension of such a branched polymer phase is four thirds. This is in good agreement with numerical simulations for large c.

Three-State Complex Valued Spins Coupled to Binary Branched Polymers in Two-Dimensional Quantum Gravity

Branched polymers, complex spins and the freezing transition

ArXiv hep-lat/9708027 (1997)

Authors:

Joao D Correia, Behrouz Mirza, John F Wheater

Abstract:

We show that by coupling complex three-state systems to branched-polymer like ensembles we can obtain models with gamma-string different from one half. It is also possible to study the interpolation between dynamical and crystalline graphs for these models; we find that only when geometry fluctuations are completely forbidden is there a crystalline phase.
