Twisted van der Waals Josephson junction based on high-Tc superconductor
Jongyun Lee, Wonjun Lee, Gi-Yeop Kim +8
Stacking two-dimensional van der Waals (vdW) materials rotated with respect to each other show versatility for the study of exotic quantum phenomena. Especially, anisotropic layere…
Many-Body Quadrupolar Sum Rule for Higher-Order Topological Insulator
Wonjun Lee, Gil Young Cho, Byungmin Kang
The modern theory of polarization establishes the bulk-boundary correspondence for the bulk polarization. In this paper, we attempt to extend it to a sum rule of the bulk quadrupol…
Metrology of Band Topology via Resonant Inelastic X-ray Scattering
Sangjin Lee, Kyung-Hwan Jin, Byungmin Kang +2
Topology is a central notion in the classification of band insulators and characterization of entangled many-body quantum states. In some cases, it manifests as quantized observabl…
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…
