Attosecond transient absorption spectroscopy in monolayer hexagonal boron nitride
Jiayu Yan, Chenkai Zhu, Rongxiang Zhang +2
We simulate the attosecond transient absorption spectroscopy (ATAS) of monolayer hexagonal boron nitride (hBN) using the time-dependent density functional theory and two-band densi…

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…
