Low Dirac Eigenmodes and the Topological and Chiral Structure of the Qcd Vacuum

Standard methods in lattice QCD consist of calculating various hadronic amplitudes by tying together appropriate combinations of quark propagators calculated on an ensemble of Monte Carlo generated gauge fields. A number of recent lattice QCD calculations have focused increasing attention on the role of low-lying eigenmodes of the Dirac operator in typical background gauge fields. The decomposi...

Topological Charge and the Laminar Structure of the QCD Vacuum

Monte Carlo studies of pure glue SU(3) gauge theory using the overlap-based topological charge operator have revealed a laminar structure in the QCD vacuum consisting of extended, thin, coherent, locally 3-dimensional sheets of topological charge embedded in 4D space, with opposite sign sheets interleaved. In this talk I discuss the interpretation of these Monte Carlo results in terms of our cu...

Uncovering Low - Dimensional Topological Structure in the Qcd Vacuum

Recently, we have pointed out that sign-coherent 4-dimensional structures can not dominate topological charge fluctuations in QCD vacuum at all scales. Here we show that an enhanced lower-dimensional coherence is possible. In pure SU(3) lattice gauge theory we find that in a typical equilibrium configuration about 80% of space-time points are covered by two oppositely-charged connected structur...

Qcd Vacuum Topological Susceptibility in a Non-local Chiral Quark Model

The topological susceptibility of QCD vacuum is studied in the framework of a covariant chiral quark model with non-local quark-quark interaction. The relation of the first moment of topological susceptibility χ(0) and the ’spin crisis’ problem is briefly discussed. It is shown, in particular, that one always gets the inequality χ(0) > χOZI . It is well known that due to UA (1) axial Adler-Bell...

Chiral vacuum alignment in dense QCD

We discuss an interesting possibility of nontrivial, quark-mass induced chiral vacuum alignment in color-flavor locking phase of cold, dense QCD. With the simplifying assumption that the gaps for quarks are identical to those of antiquarks and the light quark masses are given bymu = md andms/md = 15, we find the true chiral vacuum can align only to one of the discrete number of directions in th...
