STRONG MAGNETIC FIELDS ON THELATTICE AND CHIRAL CONDENSATE

CHIRAL CONDENSATE IS THE FUNDAMENTALQUANTITY IN QCD

We get an agreement with the chiral perturbation theory: the chiral condensate is a linear function of the strength of the magnetic field!

Zero fields, B=0no clear visible

localization [but in fact the localization

exists on 2D surfaces]

Non-zero fields, B ~ a few GeV2

Localization appears at

Lowest Landau Level

LOCALIZATION OF DIRAC EIGENMODES

1. We observe that the chiral condensate is proportional to the strength of the magnetic field.

2. Microscopic mechanism for the chiral enhancement: localization of fermions in the vacuum
