Higher-Order Topological Systems and Their Sub-Symmetry-Protected Topology
Myungjun Kang, Wonjun Sung, Sonu Verma +1
Symmetry and topology are essential principles in topological physics. Recently, the idea of sub-symmetry-protected topology -- where some of the original symmetries are broken whi…
Sub-symmetry Protected Topology in Topological Insulators and Superconductors
Myungjun Kang, Mingyu Lee, Sangmo Cheon
Exploration of topology protected by a certain symmetry is central in condensed matter physics. A recent idea of sub-symmetry-protected (SSP) topology--remains of a broken symmetry…
Evidence of surface -wave superconductivity and higher-order topology in MoTe
Sangyun Lee, Myungjun Kang, Duk Y. Kim +4
Exploration of nontrivial superconductivity and electronic band topology is at the core of condensed matter physics and applications to quantum information. The transition-metal di…
Revealing inverted chirality of hidden domain wall states in multiband systems without topological transition
Seung-Gyo Jeong, Sang-Hoon Han, Tae-Hwan Kim +1
Chirality, a fundamental concept from biological molecules to advanced materials, is prevalent in nature. Yet, its intricate behavior in specific topological systems remains poorly…
Topological Domain-Wall States Hosting Quantized Polarization and Majorana Zero Modes Without Bulk Boundary Correspondence
Sang-Hoon Han, Myungjun Kang, Moon Jip Park +1
Bulk-boundary correspondence is a concept for topological insulators and superconductors that determines the existence of topological boundary states within the tenfold classificat…
Circular dichroism of emergent chiral stacking orders in quasi-one-dimensional charge density waves
Sun-Woo Kim, Hyun-Jung Kim, Sangmo Cheon +1
Chirality-driven optical properties in charge density waves are of fundamental and practical importance. Here, we investigate the interaction between circularly polarized light and…
