Congratulations on our new paper! ‘Tunable terahertz oscillation arising from Bloch-point dynamics in chiral magnets’

July 1, 2020

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 …

THz-oscillating electric signal from Bloch point dynamics

December 2, 2019

In this work, our considerations go beyond static skyrmions, and we theoretically show that the formation/annihilation of both skyrmions and antiskyrmions is enabled by the transient creation and propagation of topological singularities (magnetic monopole-like Bloch points) …
