Probing Berry phase effect in topological surface states
Ya Bai, Yang Jiang, Wenyang Zheng +5
We have observed the Berry phase effect associated with interband coherence in topological surface states (TSSs) using two-color high-harmonic spectroscopy. This Berry phase accumu…

Waveform-Controlled Terahertz Radiation from the Air Filament Produced by Few-Cycle Laser Pulses
Ya Bai, Liwei Song, Rongjie Xu +7
Waveform-controlled Terahertz (THz) radiation is of great importance due to its potential application in THz sensing and coherent control of quantum systems. We demonstrated a nove…
