Singular Vertices and the Triangulation Space of the D-sphere
S. Catterall, G. Thorleifsson, J. Kogut +1
By a sequence of numerical experiments we demonstrate that generic triangulations of the sphere for contain one {\it singular} simplex. The mean number of element…
Pathologies of Quenched Lattice QCD at non--zero Density and its Effective Potential
M. -P. Lombardo, J. B. Kogut, D. K. Sinclair
We simulate lattice QCD at non--zero baryon density and zero temperature in the quenched approximation, both in the scaling region and in the infinite coupling limit. We investigat…
Electromagnetic Self-Duality in a Lattice Model
Simon Hands, John B. Kogut
We formulate a Euclidean lattice theory of interacting elementary spin-half electric and magnetic charges, which we refer to as electrons and magnetic monopoles respectively. The m…
Phase Transitions at Finite Temperature and Dimensional Reduction for Fermions and Bosons
A. Kocic, J. B. Kogut
In a recent Letter we discussed the fact that large- expansions and computer simulations indicate that the universality class of the finite temperature chiral symmetry restorati…
The U(1) Gross-Neveu Model at Non-Zero Chemical Potential
S. Hands, S. Kim, J. B. Kogut
The four-fermi model with continuous chiral symmetry is studied in three dimensions at non-zero chemical potential using both the expansion and computer simulations. Fo…
On the Interplay of Monopoles and Chiral Symmetry Breaking in Non-Compact Lattice QED
J. B. Kogut, K. -C. Wang
Non-compact lattice QED is simulated for various numbers of fermion species ranging from 8 through 40 by the exact Hybrid Monte Carlo algorithm. Over this range of , chi…
