Description
I will discuss the issue of Landau levels of quarks in lattice QCD in
an external magnetic field. In two dimensions the lowest Landau level
can be identified unambiguously even if the strong interactions are
turned on. This allows to define a "lowest Landau level" also in the
four-dimensional case. It is then possible to study to what extent the
effect of a magnetic field on observables can be explained in terms of
the lowest Landau level, and test the validity of low-energy models of
QCD that make use of the lowest-Landau-level approximation.
