Phases of planar QCD on the torus
Rajamani Narayanan, Herbert Neuberger
At infinite N, continuum Euclidean SU(N) gauge theory defined on a symmetrical four torus has a rich phase structure with phases where the finite volume system behaves as if it had…
First experiences with HMC for dynamical overlap fermions
Achim Bode, Urs M. Heller, Robert G. Edwards +1
We describe an HMC algorithm for dynamical overlap fermions which makes use of their good chiral properties. We test the algorithm in the Schwinger model. Topological sectors are r…
Topology and Chiral Symmetry in QCD with Overlap Fermions
Robert G. Edwards, Urs M. Heller, Joe Kiskis +1
We briefly review the overlap formalism for chiral gauge theories, the overlap Dirac operator for massless fermions and its connection to domain wall fermions. We describe properti…
Running Coupling in pure gauge theories using the Schrödinger functional
Rajamani Narayanan
Schrödinger functional, the propagation kernel for going from some field configuration at time to some other configuration at , is used to define a running coupling,…
Random Walks and the Correlation Length Critical Exponent in Scalar Quantum Field Theory
Joe Kiskis, Rajamani Narayanan, Pavlos Vranas
The distance scale for a quantum field theory is the correlation length , which diverges with exponent as the bare mass approaches a critical value. If ,…
