摘要：
We study the effects of magnetic fields on the phase diagram of strongly interacting matter using the Nambu-Jona-Lasinio model and its finite temperature extension which includes a coupling to the Polyakov loop. Emphasis is laid on the phase structure and its dependence on the parameters defining the model. We consider two parameter sets showing that they lead to rather different results, especially at low temperatures. The phenomena of magnetic catalysis and its counterpart, magnetic anti-catalysis, are also discussed. (C) 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
