[HTML][HTML] Evidence that centre vortices underpin dynamical chiral symmetry breaking in SU (3) gauge theory

A Trewartha, W Kamleh, D Leinweber - Physics Letters B, 2015 - Elsevier
The link between dynamical chiral symmetry breaking and centre vortices in the gauge fields
of pure SU (3) gauge theory is studied using the overlap-fermion quark propagator in Lattice …

Connection between center vortices and instantons through gauge-field smoothing

A Trewartha, W Kamleh, D Leinweber - Physical Review D, 2015 - APS
A recent lattice study of the Landau-gauge overlap quark propagator has shown a
connection between center vortices and dynamical chiral symmetry breaking in SU (3) …

Centre vortex removal restores chiral symmetry

A Trewartha, W Kamleh… - Journal of Physics G …, 2017 - iopscience.iop.org
