Our recent theoretical paper on “Tunable terahertz oscillation arising from Bloch-point dynamics in chiral magnets” has now been published at Physical Review Research. This work arose from a collaboration between the University of Manchester(NEST group, Skyrmionics group, and Theoretical physics group) with the ETH Zürich (Metal Physics and Technology group). It reveals that the formation/annihilation of skyrmions will give rise to an emergent electric field with the frequency in the THz regime. The electric signal is due to the ultra-fast Bloch-point propagation, and both the amplitude and frequency can be tuned by the manipulation of Bloch-point dynamics. Our studies provide a concept of directly exploiting topological singularities which may be relevant for THz skyrmion-based electronic devices …
