Renormalizable Abelian-projected effective gauge theory derived from Quantum Chromodynamics
Abstract We show that an effective Abelian gauge theory can be obtained as a renormalizable theory from QCD in the maximal Abelian gauge. The derivation improves the previous version which was obtained by one of the authors and was called the Abelianprojected effective gauge theory. This result supports a view that we can construct an effective Abelian gauge theory from QCD without losing chara...
متن کاملVortex Structure vs. Monopole Dominance in Abelian-Projected Gauge Theory
We find that Polyakov lines, computed in abelian-projected SU(2) lattice gauge theory in the confined phase, have finite expectation values for lines corresponding to two units of the abelian electric charge. This means that the abelian-projected lattice has at most Z2, rather than U(1), global symmetry. We also find a severe breakdown of the monopole dominance approximation, as well as positiv...
متن کاملSome reasons not to use spin projected density functional theory
Spin unrestricted calculations using density functional theory can yield wave functions with spin contamination. In conventional post Hartree–Fock calculations ~such as Mo”ller–Plesset perturbation theory!, spin projection can ameliorate some of the problems caused by spin contamination. However, spin projection can seriously degrade the quality of potential energy surfaces calculated by densit...
متن کاملThe Projected Three-point Correlation Function: Theory and Observations
We report results for the angular three-point galaxy correlation function in the APM survey and compare them with theoretical expectations. For the first time, these measurements extend to sufficiently large scales to probe the weakly non-linear regime. On large scales, the results are in good agreement with the predictions of non-linear cosmological perturbation theory, for a model with initia...
متن کاملTopological Aspect of Abelian Projected SU(2) Lattice Gauge Theory
We show that the hypothesis of abelian dominance allows QCD-monopoles to preserve the topological feature of the QCD vacuum within SU(2) lattice gauge theory. An analytical study is made to find the relationship between the topological charge and QCD-monopoles in the lattice formulation. The topological charge is explicitly represented in terms of the monopole current and the abelian component ...
