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…
Spin-orbit-parity coupled superconductivity in topological monolayer WTe
Ying-Ming Xie, Benjamin T. Zhou, K. T. Law
Recent experiments reported gate-induced superconductivity in the monolayer 1T-WTe which is a two-dimensional topological insulator in its normal state [1, 2]. The in-plane…
Signature of a pair of Majorana zero modes in superconducting gold surface states
Sujit Manna, Peng Wei, Yingming Xie +3
Under certain conditions, a fermion in a superconductor can separate in space into two parts known as Majorana zero modes, which are immune to decoherence from local noise sources…
Evidence of Higher Order Topology in Multilayer WTe from Josephson Coupling through Anisotropic Hinge States
Yong-Bin Choi, Yingming Xie, Chui-Zhen Chen +12
The noncentrosymmetric Td-WTe, previously known as a type-II Weyl semimetal, is expected to have higher order topological phases with topologically protected, helical one-dimen…
Strongly enlarged topological regime and enhanced superconducting gap in nanowires coupled to Ising superconductors
Ying-Ming Xie, Benjamin T. Zhou, T. K. Ng +1
An external magnetic field is needed to drive a nanowire in proximity to an s-wave superconductor into a topological regime which supports Majorana end states. However, a magnetic…
Spectroscopic Fingerprint of Chiral Majorana Modes at the Edge of a Quantum Anomalous Hall Insulator / Superconductor Heterostructure
J. Shen, J. Lyu, J. Z. Gao +14
With the recent discovery of the quantum anomalous Hall insulator (QAHI), which exhibits the conductive quantum Hall edge states without external magnetic field, it becomes possibl…
