The Structure of Flux-tubes in SU(2)
A. M. Green, C. Michael, P. S. Spencer
The spatial distribution of the action and energy in the colour fields of flux-tubes is studied in lattice SU(2) field theory for static quarks at separations up to 1 fm. Special a…
Sum rules and 2-quark flux-tube structure
A. M. Green, P. S. Spencer, C. Michael
Sum rules -- relating the static quark potential V(R) to the spatial distribution of the action and energy in the colour fields of flux-tubes -- are applied in three ways: 1) To ex…
Non-perturbative determination of beta-functions and excited string states from lattices
C. Michael, A. M. Green, P. S. Spencer
We use lattice sum rules for the static quark potential to determine the beta-function for symmetric and asymmetric lattices non-perturbatively. We also study the colour field dist…
Cooling and the SU(2) Instanton Vaccuum
C. Michael, P. S. Spencer
We present results of an investigation into the nature of instantons in 4-dimensional pure gauge lattice \ obtained from configurations which have been cooled using an under…
Instanton size distributions from calibrated cooling
C. Michael, P. S. Spencer
Using an under-relaxed cooling algorithm we investigated the vacuum in the model and pure gauge . We calibrated the amount of cooling performed to have simil…
Instanton size distribution in O(3)
C. Michael, P. S. Spencer
We present calculations of the size distribution of instantons in the 2d O(3) non-linear sigma-model, and briefly discuss the effects cooling has upon the configurations and the to…
