Topological Invariants of a Filling-Enforced Quantum Band Insulator
Abijith Krishnan, Ashvin Vishwanath, Hoi Chun Po
Traditional ionic/covalent compound insulators arise from a commensuration between electron count and system volume. On the other hand, conventional topological insulators, outside…
Topological Descendants of Multicritical EuTl2
Lin-Lin Wang, Hoi Chun Po, Robert-Jan Slager +1
The past decades have witnessed a transformation in characterizing condensed matter systems with topology. Aided by a refined understanding of topological band structures with crys…
Fractional Corner Charge of Sodium Chloride
Haruki Watanabe, Hoi Chun Po
Recent developments in higher-order topological phases have elucidated on the relationship between nontrivial multipole moments in the bulk and the emergence of fractionally quanti…
-enriched symmetry indicators for topological superconductors in the 1651 magnetic space groups
Seishiro Ono, Hoi Chun Po, Ken Shiozaki
While the symmetry-based diagnosis of topological insulators and semimetals has enabled large-scale discovery of topological materials candidates, the extension of these approaches…
Topological flat bands in frustrated kagome lattice CoSn
Mingu Kang, Shiang Fang, Linda Ye +8
Electronic flat bands in momentum space, arising from strong localization of electrons in real space, are an ideal stage to realize strong correlation phenomena. In certain lattice…
Symmetry indicators of band topology
Hoi Chun Po
Topological materials are quantum materials with nontrivial ground-state entanglement that are irremovable so long as certain rules, like invariance under symmetries and the existe…
