Résumé :
I discuss transport phenomena related to quantum anomalies, which can play an important role in off-central heavy-ion collisions and in condensed matter systems such as Dirac and Weyl semimetals. I present numerical studies of the most important signatures of anomalous transport, such as the enhancement of electric conductivity in magnetic field (negative magnetoresistance) and dynamical instabilities in non-equilibrium chiral plasma. Furthermore, I argue that anomalous transport coefficients, despite being fixed by thermodynamic consistency in the hydrodynamic limit, allow for non-perturbative corrections in phases with spontaneously broken chiral symmetry.
