Classical symmetry enriched topological orders and distinct monopole charges for dipole-octupole spin ices
Pengwei Zhao, Gang v. Chen
Distinct symmetry enriched topological orders often do not have classical distinctions. Motivated by the recent progress on the pyrochlore spin ice materials based on the dipole-oc…
Magnetopological mechanics in Maxwell lattice frustrated Mott insulators
Hong-Hao Song, Pengwei Zhao, Gang v. Chen
Topological boundary modes, a hallmark of quantum topological phases, remarkably occur in classical mechanical systems through an interesting correspondence with the quantum case.…
Multipolar ferroelectricity in the Mott regime
Pengwei Zhao, Jiahao Yang, Gang v. Chen
Ferroelectricity has been one major focus in modern fundamental research and technological application. We consider the physical origin of improper ferroelectricity in Mott insulat…
Z topological orders in kagomé dipolar systems: Feedback from Rydberg quantum simulator
Pengwei Zhao, Gang v. Chen
The mutual feedback between quantum condensed matter and cold atom physics has been quite fruitful throughout history and continues to inspire ongoing research. Motivated by the re…
Topological effect on the Anderson transition in chiral symmetry classes
Pengwei Zhao, Zhenyu Xiao, Yeyang Zhang +1
In this Letter, we propose a mechanism of an emergent quasi-localized phase in chiral symmetry classes, where wave function along a spatial direction with weak topology is delocali…
