Nonequilibrium dynamics of doped Chern ferromagnets

Interplay of strong electronic correlations and topology render twisted MoTe2 a fascinating platform for condensed matter physics. I will first present experiments demonstrating steady-state optical orientation of the spin-valley degree of freedom of holes in Chern bands of twisted MoTe2. I will then describe the dynamics of itinerant and Chern ferromagnets in the presence of an opposing magnetic field. Our experiments reveal that the nonequilibrium dynamics of the ferromagnetic domains is substantially more sensitive to the precise filling factor around Chern insulator states than standard transport or optical measurements.
