Matter in extremely strong magnetic fields
Dr. Gunnar Bali, Institut für Theoretische Physik, Universität Regensburg

While magnetic field strengths created in solid state physics laboratory experiments do not exceed 106
gauss, much stronger fields can be present in compact astrophysical objects. For instance near the surface
of a magnetar these can reach values as high as 1015 gauss, with even higher values towards the core. In
these fields atoms become essentially two-dimensional objects, with a rich phenomenology.

Recently, it was realized that in heavy ion collisions at the Brookhaven National Lab as well as at the Large
Hadron Collider at CERN even larger field strengths are being generated, within very small volumes and for
very short time periods. The presence of these fields will affect properties of strongly interacting matter,
composed of quarks and gluons, possibly with observable consequences.

I will describe theoretical expectations relating to matter in such environments. These have mostly been
obtained by simulating quantum chromodynamics on a spacetime lattice on supercomputers.
