Fixed point action and topological charge for SU(2) gauge theory
Instantons in the QCD vacuum can explain the UA(1) problem, and they could be responsible for the low energy hadron and glueball spectrum and the chiral phase transition as well[1]. Instantons have been studied on the lattice for over a decade but these studies have produced about as much controversy as physical results. The problems are three-fold: 1) Instantons are not conserved by topology o...
متن کاملTopological Charge Membranes in 2d and 4d Gauge Theory *
Local topological charge structure in the 2D CP(N-1) sigma models is studied using the overlap Dirac operator. Long-range coherence of topological charge along locally 1D regions in 2D space-time is observed. We discuss the connection between these results and the recent discovery of coherent 3D sheets of topological charge in 4D QCD. In both cases, coherent regions of topological charge form a...
متن کاملScaling topological charge in the CP model using a fixed point action
We define a fixed point action in two-dimensional lattice CP models. The fixed point action is a classical perfect lattice action, which is expected to show strongly reduced cut-off effects in numerical simulations. Furthermore, the action has scale invariant instanton solutions, which enables us to define a topological charge without topological defects. We present results for the scaling of t...
متن کاملA Topological Fixed-Point Index Theory for Evolution Inclusions
In the paper we construct a topological fixed-point theory for a class of set-valued maps which appears in natural way in boundary value problems for differential inclusions. Our construction is based upon the notion of (U, V )-approximation in the sense of Ben-El-Mechaiekh and Deguire. As applications we consider initial-value problems for nonlinear evolution inclusions of the type x′(t) ∈ −A(...
متن کاملTopological Gauge Theory and Twistors
By use of harmonic superfields, Witten’s topological gauge theory is written as a field theory on a supertwistor space. Further, using the realisation of complex compactified Minkowski space as a quadric in CP , we show that the theory has a simple formulation in terms of analytic superfields on super-CP 5 ×CP .
