Nonresonant nonlinear magnonics in an antiferromagnet
Gu-Feng Zhang, Sheikh Rubaiat Ul Haque, Kelson J. Kaj +7
Antiferromagnets exhibit rapid spin dynamics in a net zero magnetic background which enables novel spintronic applications and interrogation of many-body quantum phenomena. The lay…
Frequency-selective terahertz wave amplification by a time-boundary-engineered Huygens metasurface
Fu Deng, Fengjie Zhu, Xiaoyue Zhou +7
Ultrafast manipulation of optical resonance can establish the time-boundary effect in time-variant media leading to a new degree of freedom for coherent control of electromagnetic…
Light-induced percolative topological phase transition in type-II Weyl semimetal WTe2
Xiaoyue Zhou, Fu Deng, Yifan Gao +5
We report on an ultrafast terahertz free-carrier dynamic study of a photo-excited WTe2 thin film. In the photo-excited state, we observe a metastable electronic state featuring neg…
