Scales of Chiral Symmetry Breaking in Quantum Chromodynamics

Physical Review Letters (1982)

John B. Kogut Michael Stone H. W. Wyld J. Shigemitsu Stephen H. Shenker

Computer simulations indicate that the range of the force responsible for chiral symmetry breaking in quantum chromodynamics is relatively short, independent of confinement, and depends strongly on the color representation of the quarks. Chiral-symmetry restoration temperatures are obtained for quarks in either the fundamental or the adjoint representations of color SU(2). Results on higher representations support the symmetry-breaking pattern ("tumbling") suggested by Raby, Dimopoulos, and Susskind.

Two-color QCD at nonzero quark-number density

Physical review. D. Particles, fields, gravitation, and cosmology/Physical review. D. Particles and fields (2001)

John B. Kogut D.K. Sinclair Simon Hands Susan Morrison

We have simulated two-color four-flavor QCD at nonzero chemical potential $\ensuremath{\mu}$ for quark number. Simulations were performed on ${8}^{4}$ and ${12}^{3}\ifmmode\times\else\texttimes\fi{}24$ lattices. Clear evidence was seen for the formation of a colorless diquark condensate which breaks quark number spontaneously, for $\ensuremath{\mu}>{\ensuremath{\mu}}_{c}\ensuremath{\sim}{m}_{\ensuremath{\pi}}/2.$ The transition appears to be second order. We have measured the spectrum of scalar and pseudoscalar bosons which shows clear evidence for the expected Goldstone boson. Our results are in qualitative agreement with those from effective Lagrangians for the potential Goldstone excitations of this theory.

Non-Compact QED_3 with N_f=1 and N_f=4

arXiv (Cornell University) (2004)

Simon Hands John B. Kogut L. Scorzato Costas Strouthos

We present numerical results for non-compact three-dimensional QED for numbers of flavors N_f=1 and N_f=4.In particular, we address the issue of whether chiral symmetry is spontaneously broken in the continuum limit, and obtain a positive answer for N_f=1, with a dimensionless condensate estimated to be beta^2 ~= O(10^-3), implying that the critical number of flavors N_fc>1. We also compare the N_f=1 and N_f=4 models by analysing the transition from strong to weak coupling behaviour using an equation of state based on a continuous phase transition. While some qualitative differences emerge, it appears difficult to determine whether N_f=4 lies above or below N_fc.
