The pulsar magnetospheres are mostly made of a force-free magnetized plasma, where the local electric field is perpendicular to the magnetic field. However, a consistent consideration of the dynamics points to the existence of transient gap regions in the magnetospheres where the projection of the electric field on the magnetic field must be nonzero. Under such conditions, the chiral anomaly can be activated and produce a nonzero chiral charge density in the plasma. The chiral asymmetry produced in the magnetospheres of magnetars can be substantial. It can trigger chiral plasma instability and possibly lead to observable phenomena in magnetars.
The speaker for this event will lead the meeting remotely. All interested graduate students and faculty are invited to attend by convening in the INT seminar room (C-421).
Participants are also welcome to join via Zoom. Zoom link will be available via announcement email, or by contacting: amccoy10[at]uw.edu or gsj6[at]uw.edu.
