Influence of center vortices on the overlap quark propagator in dynamical QCD
Adam Virgili, Waseem Kamleh, Derek B. Leinweber
There is strong evidence supporting center vortices as underpinning confinement and dynamical chiral symmetry breaking -- the two key features of nonperturbative QCD. In our recent…
Numerical indication that center vortices drive dynamical mass generation in QCD
Waseem Kamleh, Derek B. Leinweber, Adam Virgili
The first calculation of the response of the momentum space quark propagator to center vortices in the ground state fields of QCD is presented. Center vortices are identified on 2+…
Emergent phenomena from centre vortices in dynamical QCD
Waseem Kamleh, James Biddle, Derek B. Leinweber +1
Quark confinement and dynamical chiral symmetry breaking are two of the most important emergent properties of the theory of quantum chromodynamics. We review recent results studyin…
Dynamical fermions, centre vortices, and emergent phenomena
Derek Leinweber, James Biddle, Waseem Kamleh +1
The non-trivial ground-state vacuum fields of QCD form the foundation of matter. Here we examine the centre vortices identified within the ground-state fields of lattice QCD. We ai…
Overlap quark propagator near the physical pion mass
Adam Virgili, Waseem Kamleh, Derek Leinweber
The Landau-gauge quark propagator is calculated using overlap fermions on 2+1-flavour dynamical fermion gauge fields from the PACS-CS collaboration with pion mass $m_π\sim 156\text…
Impact of centre vortex removal on the Landau-gauge quark propagator in dynamical QCD
Adam Virgili, Waseem Kamleh, Derek Leinweber
The important role of centre vortices in dynamical chiral symmetry breaking and corresponding dynamical mass generation has been demonstrated in pure gauge studies of the Landau-ga…
Smoothing algorithms for projected center-vortex gauge fields
Adam Virgili, Waseem Kamleh, Derek Leinweber
We study the application of gauge field smoothing methods to -projected center-vortex gauge fields. Due to the proportionality of the vortex links t…
Role of chiral symmetry in the nucleon excitation spectrum
Adam Virgili, Waseem Kamleh, Derek Leinweber
The origin of the low-lying nature of the *(1440), or Roper resonance, has been the subject of significant interest for many years, including several investigations using lattic…
