Topological Band Theory for Non-Hermitian Hamiltonians.
TL;DR: The topological band theory for systems described by non-Hermitian Hamiltonians, whose energy spectra are generally complex, is developed and "gapped" bands in one and two dimensions are classified by explicitly finding their topological invariants.

TL;DR: The nonlinear Hall effect is observed in bilayer WTe2 in the absence of a magnetic field, providing a direct measure of the dipole moment of the Berry curvature, which arises from layer-polarized Dirac fermions in bilayers WTe 2 under time-reversal-symmetric conditions.
Journal ArticleDOI
Electrically switchable Berry curvature dipole in the monolayer topological insulator WTe 2
Su-Yang Xu,Qiong Ma,Huitao Shen,Valla Fatemi,Sanfeng Wu,Tay-Rong Chang,Guoqing Chang,Andrés M. Mier Valdivia,Ching-Kit Chan,Quinn Gibson,Jiadong Zhou,Zheng Liu,Kenji Watanabe,Takashi Taniguchi,Hsin Lin,Robert J. Cava,Liang Fu,Nuh Gedik,Pablo Jarillo-Herrero +18 more
TL;DR: In this paper, the authors used mid-infrared optoelectronic microscopy to investigate the Berry curvature in monolayer WTe2 and observed an in-plane circular photogalvanic current even under normal incidence.
Journal ArticleDOI
Nodal-link semimetals
TL;DR: In this article, a general recipe based on the Hopf map for constructing models of nodal-link semimetals is proposed, which host linked nodal rings in the Brillouin zone.
