Topology of dynamical lattice configurations including results from dynamical overlap fermions

Understand

We investigate how the topological charge density in lattice QCD simulations is affected by violations of chiral symmetry caused by the fermion action.

• To this end we compare lattice configurations generated with a number of different actions including first configurations generated with exact dynamical overlap quarks.
• We visualize the topological profiles after mild smearing.
• In the topological charge correlator we measure the size of the positive core, which is known to shrink to zero extension in the continuum limit.
