Topological Crystalline Magnets: Symmetry-Protected Topological Phases of Fermions
Haruki Watanabe, Liang Fu
We introduce a novel class of interaction-enabled topological crystalline insulators in two- and three-dimensional electronic systems, which we call "topological crystalline magnet…

Energy gap of neutral excitations implies vanishing charge susceptibility
Haruki Watanabe
In quantum many-body systems with a U(1) symmetry, such as the particle number conservation and the axial spin conservation, there are two distinct types of excitations: charge-neu…

Filling-Enforced Gaplessness in Band Structures of the 230 Space Groups
Haruki Watanabe, Hoi Chun Po, Michael P. Zaletel +1
Nonsymmorphic symmetries like screws and glides produce electron band touchings, obstructing the formation of a band insulator and leading, instead, to metals or nodal semimetals e…
