Unveiling Topological Hinge States in the Higher-Order Topological Insulator WTe Based on the Fractional Josephson Effect
Yong-Bin Choi, Jinho Park, Woochan Jung +3
Higher-order topological insulators (HOTIs) represent a novel class of topological materials, characterised by the emergence of topological boundary modes at dimensions two or more…
Crystalline superconductor-semiconductor Josephson junctions for compact superconducting qubits
Jesse Balgley, Jinho Park, Xuanjing Chu +11
The narrow bandgap of semiconductors allows for thick, uniform Josephson junction barriers, potentially enabling reproducible, stable, and compact superconducting qubits. We study…
Steady Floquet-Andreev States Probed by Tunnelling Spectroscopy
Sein Park, Wonjun Lee, Seong Jang +7
Engineering quantum states through light-matter interaction has created a new paradigm in condensed matter physics. A representative example is the Floquet-Bloch state, which is ge…
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…
Short Ballistic Josephson Coupling in Planar Graphene Junctions with Inhomogeneous Carrier Doping
Jinho Park, Jae Hyeong Lee, Gil-Ho Lee +5
We report on short ballistic (SB) Josephson coupling in junctions embedded in a planar heterostructure of graphene. Ballistic Josephson coupling is confirmed by the Fabry-Perot-typ…
