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…
