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…

Absence of Physical Walls in Hot Gauge Theories
Joe Kiskis
This paper shows that there are no {\em physical} walls in the deconfined, high-temperature phase of lattice gauge theory. In a Hamiltonian formulation, the interface in the…

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 ,…
