2021-08-17 Seminar Report

Shunichiro Kinoshita (Chuo U.) gave a talk on "Application of AdS/CFT to non-equilibrium phenomena in external electric fields. "After a brief introduction to the AdS/CFT correspondence, Shunichiro analyzed a holographic QCD system under strong electric fields constructed with D3/D7 branes. Shunichiro considered two kinds of electric-field configurations.The first one was a field with a sudden switching on (quenched setup). Shunichiro discussed how the confinement-deconfinement phase transition occurs and showed the possibility of deconfinement driven by turbulence. The second configuration was rotating electric fields. Shunichiro discussed how the frequency of the electric field affects the phase transition and argued the possibility of a novel state, distinct from the vacuum, for infinitesimally small electric fields with finite frequency.
