Description

The properties of strongly interacting matter at finite temperature in a
magnetized medium have received a great deal of attention in recent years.
This is mainly due to the so called Inverse Magnetic Catalysis (IMC)
phenomenon found by LQCD calculations, whereby the pseudo critical quiral
phase transition temperature and the quark condensate above this
transition temperature decrease as a function of the magnetic field
intensity. In this talk I report on recent findings on the strong coupling
properties when its temperature and magnetic field dependence are
considered. By means of a renormalization group analysis, I show that when
the magnetic field intensity is the dominant scale, the strong coupling
increases as a function of the field strength. However, when the
temperature is the dominant scale the strong coupling decreases as a
function of the field strength. I also argue that this phenomenon is
linked to the IMC phenomenon.
