abstract
We perform the first systematic study of the nonlinear electromagnetic currents induced by external electromagnetic field in quark-gluon plasma, both in the two cases that the inhomogeneity of electromagnetic field is small (large) so that the collision effect is important (negligible). In the former case, we list and classify possible components of the currents in a systematic way, and make an order estimate of each component by using the Boltzmann equation in the relaxation time approximation. In the latter case, we explicitly calculate the quadratic current by using the Vlasov equation, and find that the current generated by the chiral magnetic effect and the quadratic current can have the same order of magnitude by using the Kadanoff-Baym equation. We also demonstrate this property by using a possible configuration of electromagnetic field realized in heavy ion collision.

Electric, thermal and thermoelectric response of a hot pion gas in a time dependent background magnetic field
The transport coefficients of a hot pion gas are recalculated under exponentially decaying background magnetic fields, showing that the field lifetime changes conductivities, thermal conductivity, and Seebeck and Nernst coefficients relative to constant-field results.
