All-optical reconstruction of valley polarization through helicity-resolved high-harmonic generation
Xiaoyu Bu, Yan Meng, Xiaohui Zhao +2
We theoretically investigate valley-resolved high-order harmonic generation in gapped graphene driven by elliptically polarized laser fields. Using two-band density-matrix simulati…

Isolated elliptically-polarized attosecond pulse generation in gapped graphene driven by linearly polarized laser fields
Xinru Song, Xiaoyu Bu, Xiaohui Zhao +3
We theoretically investigate high-order harmonic generation (HHG) and its ellipticity in gapped graphene, driven by a femtosecond short-pulse laser at various orientation angles, e…
