Stable topological phase transitions without symmetry indications in NaZnSbBi
Jaemo Jung, Dongwook Kim, Youngkuk Kim
We study topological phase transitions in tetragonal NaZnSbBi, driven by the chemical composition . Notably, we examine mirror Chern numbers that change without symm…
On-demand quantum spin Hall insulators controlled by two-dimensional ferroelectricity
Jiawei Huang, Xu Duan, Sunam Jeon +4
The coexistence of ferroelectric and topological orders in two-dimensional (2D) atomic crystals allows non-volatile and switchable quantum spin Hall states. Here we offer a general…
Higher-Order Topological Instanton Tunneling Oscillation
Moon Jip Park, Sunam Jeon, SungBin Lee +2
We propose a new type of instanton interference effect in two-dimensional higher-order topological insulators. The intercorner tunneling consists of the instanton and the anti-inst…
Higher-Order Topological Insulator in Twisted Bilayer Graphene
Moon Jip Park, Youngkuk Kim, Gil Young Cho +1
Higher-order topological insulators are newly proposed topological phases of matter, whose bulk topology manifests as localized modes at two- or higher-dimensional lower boundaries…
Stiefel-Whitney classes and topological phases in band theory
Junyeong Ahn, Sungjoon Park, Dongwook Kim +2
In this article, we review the recent progress in the study of topological phases in systems with space-time inversion symmetry . is an anti-unitary…
Dual topological nodal line and nonsymmorphic Dirac semimetal in three dimensions
Yun-Tak Oh, Hong-Guk Min, Youngkuk Kim
Previously known three-dimensional Dirac semimetals (DSs) occur in two types -- topological DSs and nonsymmorphic DSs. Here we present a novel three-dimensional DS that exhibits bo…
