Selected publications
EUV solids: to the extreme
High-order harmonic generation in solids can be pushed to the extreme ultraviolet part of the electromagnetic spectrum, opening a new era of scientific discovery and application.
Optical attosecond pulses
Attosecond pulses do not need to be XUV pulses. One can generate attosecond pulses that are purely optical, whose spectrum ranging more than two octaves, covering the whole visible spectrum.
A theoretical perspective on HHG from solids
It is surprising to see that the pure implementation of the semiconductor Bloch equations could be applicable to a variety of experiments.
Characterizing condensed matters using high-harmonic spectroscopy
High-harmonic spectroscopy of solids can be utilized to learn about the electronic properties of solids. Berry curvature could be one of them.
