摘要

In Weyl semimetal (TaSe4)2I, excitation of femtosecond optical pulses induces terahertz emission in the CDW state, arising from contributions of ultrafast photocurrent and various collective modes. Due to topologically non-trivial linear bands, we discover that properties of the collective modes at low temperatures can be manipulated with an ultrafast manner.
