Highly anisotropic interlayer magnetoresitance in ZrSiS nodal-line Dirac semimetal

Oleg Yazyev, Xiaoqiang Wang, Quansheng Wu, Shengnan Zhang

We instigate the angle-dependent magnetoresistance (AMR) of the layered nodal-line Dirac semimetal ZrSiS for the in-plane and out-of-plane current directions. This material has recently revealed an intriguing butterfly-shaped in-plane AMR whose origin is n ...

Magnetoresistance from Fermi surface topology

Oleg Yazyev, Yizhu Liu, Quansheng Wu, Shengnan Zhang

Extremely large nonsaturating magnetoresistance has recently been reported for a large number of both topologically trivial and nontrivial materials. Different mechanisms have been proposed to explain the observed magnetotransport properties, yet without a ...

Non-Abelian band topology in noninteracting metals

Quansheng Wu

Electron energy bands of crystalline solids generically exhibit degeneracies called band-structure nodes. Here, we introduce non-Abelian topological charges that characterize line nodes inside the momentum space of crystalline metals with space-time invers ...

Automated construction of symmetrized Wannier-like tight-binding models from ab initio calculations

Quansheng Wu

Wannier tight-binding models are effective models constructed from first-principles calculations. As such, they bridge a gap between the accuracy of first-principles calculations and the computational simplicity of effective models. In this work, we extend ...

Topological phase transitions driven by strain in monolayer tellurium

Oleg Yazyev, Wei Zhang, Quansheng Wu

Two-dimensional (2D) Xenes of a single type of element can offer fascinating electronic properties, such as massless Dirac fermions for extremely high charge-carrier mobility and topological insulators for dissipationless electron transport. However, the r ...

Topological phonons and thermoelectricity in triple-point metals

Quansheng Wu

Recently published discoveries of acoustic- and optical-mode inversion in the phonon spectrum of certain metals became the first realistic example of noninteracting topological bosonic excitations in existing materials. However, the observable physical and ...
