Attosecond All-Optical Retrieval of Valley Polarization via Circular Dichroism in Transient Absorption
Wenqing Li, Xiaosong Zhu, Pengfei Lan +5
We propose a scheme for retrieving the ultrafast valley polarization (VP) dynamics in two-dimensional hexagonal materials via attosecond circular dichroism (CD) transient absorptio…

Helicity-selected near-circularly polarized attosecond pulses generated from mixed He-Ne gases
Chunyang Zhai, Xiaosong Zhu, Yingbin Li +4
We present and theoretically demonstrate a method for generating helicity-selected near-circularly polarized attosecond pulses in mixed He-Ne gases using bichromatic counter-rotati…

High-purity valley-polarized currents induced by bichromatic optical fields in two-dimensional materials
Wenqing Li, Xiaosong Zhu, Liang Li +4
Producing currents predominantly from a single valley, namely valley-polarized currents, at optical-cycle timescales is an important aspect of the petahertz valleytronics, yet it r…
