Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Xiaotai Wu, Wen-Sheng Zhao, Yuhua Cheng, Yue Hu | Summary: We study the atomic collapse phenomenon in $K$ and $K’$ valley of gapped graphene. Bound states induced by Coulomb impurity in the gap turn into atomic collapse resonances as the charge increases beyond the supercritical […]
