摘要:

在非定域推广的Polyakov-Nambu-Jona-Lasinio模型的基础上,研究了强相互作用物质在均匀强外磁场中的行为.的形式主义的详细描述,考虑零和有限温度的情况下。特别是,我们分析了磁场的手性恢复和解除限制的转变,这是发现发生在大致相同的临界温度的效果。我们的结果表明,这些模型提供了一个自然的框架来解释在格点量子色动力学计算中发现的逆磁催化现象。

英文摘要:

We study the behavior of strongly interacting matter under a uniform intense external magnetic field in the context of nonlocal extensions of the Polyakov-Nambu-Jona-Lasinio model. A detailed description of the formalism is presented, considering the cases of zero and finite temperature. In particular, we analyze the effect of the magnetic field on the chiral restoration and deconfinement transitions, which are found to occur at approximately the same critical temperatures. Our results show that these models offer a natural framework to account for the phenomenon of inverse magnetic catalysis found in lattice QCD calculations.
