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…
Electron motion enhanced high harmonic generation in xenon clusters
Na Li, Peng Liu, Ya Bai +3
Atomic clusters presents an isolated system that models the bulk materials whose mechanism of HHG remains uncertain, and a promising medium to produce HHG beyond the limited conver…
Revealing plasma oscillation in THz spectrum from laser plasma of molecular jet
Na Li, Ya Bai, Tianshi Miao +3
Contribution of plasma oscillation to the broadband terahertz emission is revealed by interacting two-color laser pulses with a supersonic jet of nitrogen molecules. Temporal and s…
Initial carrier-envelope phase of few-cycle pulses determined by THz emission from air plasma
Rongjie Xu, Ya Bai, Liwei Song +3
The evolution of THz waveform generated in air plasma provides a sensitive probe to the variation of the carrier envelope phase (CEP) of propagating intense few-cycle pulses. Our e…
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…
