Lattice quantum chromodynamics with FLIC overlap fermions / Waseem Kamleh.

Bibliography: p. 222-229.vii, 229 p. : ill. ; 30 cm.Constructs an overlap operator to realise chiral symmetry on a quantum chromodynamic lattice that is faster to evaluate computationally than the Dirac operator, though the use of an alternative kernel, the Fat Link Irrelevant Clover (FLIC) action. Investigates the properties of FLIC Overlap fermions through the quark propagator in momentum space via topology. These calculations are performed in both the quenched and the dynamical kernel approximation, a type of partial quenching. In the quenched approximation, the effects of fermion vacuum fluctuations are neglected in the creation of gluon field configurations, In the partially quenched approximation, a different fermionic action is used in the sea and valence sectors. Develops a means of including the effects of FLIC sea fermions in the gluonic background field and presents an implementation of code optimised for cluster computing.Thesis (Ph.D.)--University of Adelaide, School of Chemistry and Physics, Discipline of Physics, 200
