Topology and chiral symmetry breaking in QCD
U. Sharan
We construct a model to study the impact of instantons on the low lying eigenvalue spectrum of the Dirac operator. The model is by necessity, approximate, though it does incorporat…

Chiral symmetry breaking and instantons in both quenched and full QCD
U. Sharan, M. Teper
We investigate the contribution that instantons make to the QCD chiral condensate for Nf= 0, 1 and 2 quark flavours. We use a simplified model: the instantons are a (weighted) gas,…
