Description |
One of the striking features of QCD, the theory of strong interactions, is the confinement of strongly charged objects. Its fundamental fields, the quarks and gluons, do not appear as asymptotic states but are bound in hadrons such as the proton. Interestingly, the most striking experimental evidence of this phenomenon is the absence of objects with fractional electric charges in nature. Combinations of QCD and electrodynamical effects also gained prominence recently with the observation of the so-called chiral magnetic effect at the Brookhaven National Laboratory where a magnetic field may induce local parity violations in QCD matter. I will report on recent work, numerically simulating QCD in Lattice regularization, in the presence of an external (electro-)magnetic field. This affects the phase transition temperature, with possible implications for heavy ion collision experiments and the early universe. |
