热磁效应诱导手性跃迁的逆磁催化作用对耦合常数的影响

Inverse magnetic catalysis for the chiral transition induced by thermo-magnetic effects on the coupling constant

Alejandro Ayala, M. Loewe, Ana Julia Mizher, R. Zamora

摘要:

在带电标量与恒定磁场相互作用的模型中,我们计算了自耦合的单圈热磁修正。计算的动机的可能性,在磁背景中的手征相变的临界温度可以通过耦合常数的依赖性的磁场的影响。我们表明,耦合作为一个功能的场强减少。这种函数依赖性又引入了对玻色子质量的修正,这导致临界温度作为场强的函数而降低。

英文摘要:

We compute the one-loop thermo-magnetic corrections to the self-coupling in a model where charged scalars interact also with a constant magnetic field. The calculation is motivated by the possibility that the critical temperature for the chiral phase transition in a magnetic background can be influenced by the dependence of the coupling constant on the magnetic field. We show that the coupling decreases as a function of the field strength. This functional dependence introduces in turn a correction to the boson masses which causes the critical temperature to decrease as a function of the field strength.
