Observation of the Axion quasiparticle in 2D MnBiTe
Jian-Xiang Qiu, Barun Ghosh, Jan Schütte-Engel +32
In 1978, Wilczek and Weinberg theoretically discovered a new boson-the Axion-which is the coherent oscillation of the field in QCD. Its existence can solve multiple fundamenta…
Topological Nature of Orbital Chern Insulators
Yueh-Ting Yao, Chia-Hung Chu, Arun Bansil +2
Ground state topologies in quantum materials have unveiled many unique topological phases with novel Hall responses. Recently, the orbital Hall effect in insulators has suggested t…
Moving Protocol of Majorana Corner Modes in a Superconducting 2D Weyl Semimetal Heterostructure
Ching-Kai Chiu, Yueh-Ting Yao, Tay-Rong Chang +1
Second-order topological superconductors host Majorana corner modes (MCMs), which are confined to specific corners of the system. This spatial restriction presents challenges for m…
Tunable High Spin Chern-Number Insulator Phases in Strained Sb Monolayer
Jacob Cook, Po-Yuan Yang, Theo Volz +8
High spin Chern-number insulators (HSCI) have emerged as a novel 2D topological phase of condensed matter that is beyond the classification of topological quantum chemistry. In thi…
