6. Chiral magnetic effect and an experimental bound on the late time magnetic field strength / Müller, Berndt ; Schäfer, Andreas
We first compare different approaches to estimates of the magnitude of the chiral magnetic effect in relativistic heavy ion collisions and show that their main difference lies in the assumptions on the length of persistence of the magnetic field generated by the colliding nuclei. [...]

7. Universal magnetoresponse in QCD and N = 4 $$ \mathcal{N}=4 $$ SYM / Endrődi, Gergely ; Kaminski, Matthias ; Schäfer, Andreas ; Wu, Jackson ; et al
Using recent lattice data on the thermodynamics of QCD in the presence of a background magnetic field, we show that the ratio of transverse to longitudinal pressure exhibits, to good accuracy, a simple scaling behavior over a wide range of temperature and magnetic field, essentially depending only on the ratio T / B $$ T/\sqrt{B} $$ .
