Zapraszamy na seminarium 16.11.2021

Dear All,
we have a pleasure to invite you to the Particle Theory Seminar on Tuesday, November 16 at 12:15:
Dr. Masoud Shokri 
(IPM Institute For Research In Fundamental Sciences, Teheran, Iran 
& Frankfurt University, Germany) "Causal instabilities of the Chern-Simons magnetohydrodynamics" This talk presents a novel instability in the Chern-Simons (or axionic) magnetohydrodynamics (MHD), arising from the spatial inhomogeneity of the axion-like field. In particular, this instability amplifies the Alfven waves in certain regions of spacetime in a way that is clearly parity-violating. The Aflven velocity reaches the speed of light in such regions, but it never exceeds it.   
Seminar will take place in the seminar room D-2-02, however, we plan to have it in hybrid mode. People interested in the on-line participation are kindly requested to let us know by email and we will send zoom coordinates.
