Quantum higher-spin Hall insulators
Takuto Kawakami, Igor Kuzmenko, Yshai Avishai +2
We develop a theory of quantum spin Hall insulators with arbitrary spin . Our analysis demonstrates that such systems support pairs of helical edge modes protec…

Subspace-Protected Topological Phases and Bulk-Boundary Correspondence
Kenji Shimomura, Ryo Takami, Daichi Nakamura +1
While tremendous research has revealed that symmetry enriches topological phases of matter, more general principles that protect topological phases have yet to be explored. In this…

Callan-Rubakov effects in topological insulators
Yusuke O. Nakai, Reuel Dsouza, Daichi Nakamura +3
The Callan-Rubakov effect describes monopole-catalyzed proton decay. While this effect is fundamental for quantum field theories, its experimental observation has remained far from…
