Occupation-Driven emission asynchronous as a Fundamental Constraint on Solid-State Attosecond Pulses
Qing-Guo Fan, Kang Lai, Wen-hao Liu +3
A newly analytic occupation-resolved theory capturing the temporal structure of attosecond pulses (APs) is derived. We validate it with real-time time-dependent density functional…

Revealing Material-Dependent Bicircular High-Order Harmonic Generation in 2D Semiconductors via Real-Space Trajectories
Qing-Guo Fan, Kang Lai, Wen-hao Liu +3
Solid-state high-order harmonic generation (HHG) presents unique features different from gases.Whereas the gaseous harmonics driven by counter-rotating bicircular (CRB) pulse unive…
