D-Theory: Field Theory via Dimensional Reduction of Discrete Variables
B. B. Beard, R. C. Brower, S. Chandrasekharan +3
A new non-perturbative approach to quantum field theory --- D-theory --- is proposed, in which continuous classical fields are replaced by discrete quantized variables which underg…
The Perfect Quark-Gluon Vertex Function
K. Orginos, W. Bietenholz, R. Brower +2
We evaluate a perfect quark-gluon vertex function for QCD in coordinate space and truncate it to a short range. We present preliminary results for the charmonium spectrum using thi…
Perfect Lattice Topology: The Quantum Rotor as a Test Case
W. Bietenholz, R. Brower, S. Chandrasekharan +1
Lattice actions and topological charges that are classically and quantum mechanically perfect (i.e. free of lattice artifacts) are constructed analytically for the quantum rotor. I…
QCD as a Quantum Link Model
R. Brower, S. Chandrasekharan, U. -J. Wiese
QCD is constructed as a lattice gauge theory in which the elements of the link matrices are represented by non-commuting operators acting in a Hilbert space. The resulting quantum…
