Geometry in transition: A model of emergent geometry
Rodrigo Delgadillo-Blando, Denjoe O'Connor, Badis Ydri
We study a three matrix model with global SO(3) symmetry containing at most quartic powers of the matrices. We find an exotic line of discontinuous transitions with a jump in the e…
A universal Dirac operator and noncommutative spin bundles over fuzzy complex projective spaces
Brian P. Dolan, Idrish Huet, Sean Murray +1
We present a universal Dirac operator for noncommutative spin and spin^c bundles over fuzzy complex projective spaces. We give an explicit construction of these bundles, which are…
A Multitrace Matrix Model from Fuzzy Scalar Field Theory
Denjoe O'Connor, Christian Saemann
We present the analytical approach to scalar field theory on the fuzzy sphere which has been developed in arXiv:0706.2493 [hep-th]. This approach is based on considering a perturba…
Matrix models on the fuzzy sphere
Brian P. Dolan, Denjoe O'Connor, Peter Presnajder
Field theory on a fuzzy noncommutative sphere can be considered as a particular matrix approximation of field theory on the standard commutative sphere. We investigate from this po…
Finite-Temperature Renormalization Group Predictions: The Critical Temperature Exponents, and Amplitude Ratios
F. Freire, Denjoe O'Connor, C. R. Stephens +1
theory at finite temperature suffers from infrared divergences near the temperature at which the symmetry is restored. These divergences are handled using renormalization gr…
Environmentally Friendly Renormalization in Finite-Temperature Field Theory
M. A. van Eijck, Denjoe O'Connor, C. R. Stephens
Contribution to the proceedings of the NATO workshop on the Electroweak Phase Transition and the Early Universe, Sintra, March 1994. To be published by Plenum Press.
