Understanding the structure of nucleon excitations from their wavefunctions
Jackson A. Mickley, Waseem Kamleh, Derek B. Leinweber +1
Relativistic wavefunctions of nucleon excitations are scrutinised to understand their node structure and the underlying role of local interpolating fields in generating the nucleon…
Novel insight into centre-vortex geometry in four dimensions
Jackson A. Mickley, Chris Allton, Ryan Bignell +1
Centre-vortex surfaces are mapped out in four dimensions within the framework of SU(3) lattice gauge theory to understand the role of secondary loops that develop in three-dimensio…
Center vortices in the novel phase of staggered fermions
Jackson A. Mickley, Derek B. Leinweber, Daniel Nogradi
The geometry of center vortices is studied in the novel lattice-artefact phase that appears with staggered fermions to elucidate any insight provided by the center-vortex degrees o…
Structure of center-vortex matter in SU(4) Yang-Mills theory
Jackson A. Mickley, Derek B. Leinweber, Luis E. Oxman
The structure of center vortices is studied in SU(4) Yang-Mills theory for the first time to illuminate the interplay between elementary (center charge ) and doubly charged…
Centre vortices in thermal lattice QCD with dynamical fermions
Jackson Mickley, Chris Allton, Ryan Bignell +1
Evidence for a second finite-temperature transition in Quantum Chromodynamics (QCD) is revealed through the study of centre vortex geometry and its temperature-dependent evolution.…
The temperature dependence of fractional topological charge objects
Jackson A. Mickley, Waseem Kamleh, Derek B. Leinweber
We present a novel method for defining the topological charge contained within distinct topological objects in the nontrivial ground-state fields of SU(N) lattice gauge theory. Suc…
