Title: Chirality generation via Schwinger Effect -real time description for CME- †Speaker: Jun'ya Kume †Abstract: The Chiral Magnetic Effect (CME) predicts electric current is induced by a magnetic field in the left-right asymmetric fermion background. Asymmetry of the background, or the transportation coefficient is conventionally expressed by the so-called chiral chemical potential. Due to such a proportionality, CME current is sometimes misunderstood as an equilibrium response, but it is not the case. In this talk, I will give a review on the Schwinger pair production with parallel E and B. Such a field configuration generates chiral asymmetry and chiral chemical potential does not enter in the production rate. In order to clarify the real-time nature of the CME, in-in evaluation of the chiral charge and the electric current is performed in such a system. References: |
