GWX-EOS Seminar by Hiroshi Funaki on August 28, 2025

In this seminar, the gyromagnetic effect, which is the interconversion between macroscopic rotation and microrotation, was discussed in the context of neutron stars. Starting from the terrestrial experiments on gyromagnetic effects, including ferromagnetic rigid bodies, liquid metal, and quark-gluon plasmas, the universality of the gyromagnetic effects is explored. Then, the four angular-velocity model was introduced to describe the dynamics of the core and crust of the neutron stars. The model provides a new mechanism to explain pulsar glitches due to the gyromagnetic effect.
