Attosecond Reconstruction of Strain Tensors via Electronic Fingerprints
Jing Li, Jiayu Yan, Guoyong Yuan +3
We demonstrate an attosecond transient absorption spectroscopy (ATAS) scheme for reconstructing strain tensors in two-dimensional materials. Using strained graphene as a prototype…

Effect of Berry connection on attosecond transient absorption spectroscopy in gapped graphene
Jiayu Yan, Hongxuan Er, Wei Dang +4
We investigate the attosecond transient absorption spectroscopy (ATAS) in gapped graphene by numerically solving the four-band density matrix equations. Our results reveal that, in…

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…
