Topological Fermi-arc-like surface states in Kramers nodal line metals
Zi-Ting Sun, Ruo-Peng Yu, Xue-Jian Gao +1
The discovery of Kramers nodal line metals (KNLMs) and Kramers Weyl semimetals (KWSs) has significantly expanded the range of metallic topological materials to all noncentrosymmetr…

Creating Localized Majorana Zero Modes in Quantum Anomalous Hall Insulator/Superconductor Heterostructures with a Scissor
Ying-Ming Xie, Xue-Jian Gao, Tai-Kai Ng +1
In this work, we demonstrate that making a cut (a narrow vacuum regime) in the bulk of a quantum anomalous Hall insulator (QAHI) creates a topologically protected single helical ch…
