The nature of the continuum limit in the 2D gauge model
S. M. Catterall, M. Hasenbusch, R. R. Horgan +1
The RP(2) gauge model is studied in 2D. We use Monte-Carlo renormalization techniques for blocking the mean spin-spin interaction, <A>, and the mean gauge field plaquette, <P>. The…
Phase Structure of Dynamical Triangulation Models in Three Dimensions
Ray L. Renken, Simon M. Catterall, John B. Kogut
The dynamical triangulation model of three-dimensional quantum gravity is shown to have a line of transitions in an expanded phase diagram which includes a coupling mu to the order…
Monte-carlo renormalization group study of gauged RP(2) spin models in two dimensions
S. M. Caterall, M. Hasenbusch, R. R. Horgan +1
The 2D RP(2) gauge model is studied using the Monte-Carlo Renormalization Group. We confirm the first-order transition reported by Solomon et al. (PL 112B, (1982)) ending in a crit…
Singular Structure in 4D Simplicial Gravity
S. Catterall, R. Renken, J. Kogut
We show that the phase transition previously observed in dynamical triangulation models of quantum gravity can be understood as being due to the creation of a singular link. The tr…
Thermodynamics of lattice QCD with two light quark flavours on a 16^3 x 8 lattice II
S. Gottlieb, U. M. Heller, A. D. Kennedy +8
We have extended our earlier simulations of the high temperature behaviour of lattice QCD with two light flavours of staggered quarks on a lattice to lower quark ma…
The Renormalization Group and Dynamical Triangulations
Ray L. Renken
A block spin renormalization group approach is introduced which can be applied to dynamical triangulations in any dimension.
