Lithium ion intercalation in thin crystals of hexagonal TaSe2 gated by a polymer electrolyte
Yueshen Wu, Hailong Lian, Jiaming He +5
Ionic liquid gating has been used to modify properties of layered transition metal dichalcogenides (TMDCs), including two-dimensional (2D) crystals of TMDCs used extensively recent…
Angle-dependent magnetoresistance as a sensitive probe of the charge density wave in quasi-one-dimensional semimetal TaNiSe
Jiaming He, Libin Wen, Yueshen Wu +7
The behavior of charge density wave (CDW) in an external magnetic field is dictated by both orbital and Pauli (Zeeman) effects. A quasi-one-dimensional (Q1D) system features Q1D Fe…
Monolayer MgC: Negative Poisson's ratio and unconventional 2D emergent fermions
Shan-Shan Wang, Ying Liu, Zhi-Ming Yu +4
Novel two-dimensional (2D) emergent fermions and negative Poisson's ratio in 2D materials are fascinating subjects of research. Here, based on first-principles calculations and the…
Quadratic contact point semimetal: Theory and material realization
Ziming Zhu, Ying Liu, Zhi-Ming Yu +5
Most electronic properties of metals are determined solely by the low-energy states around the Fermi level, and for topological metals/semimetals, these low-energy states become di…
Almost ideal nodal-loop semimetal in monoclinic CuTeO material
Si Li, Ying Liu, Botao Fu +3
Nodal-loop semimetals are materials in which the conduction and valence bands cross on a one-dimensional loop in the reciprocal space. For the nodal-loop character to manifest in p…
Band dependence of charge density wave in quasi-one-dimensional Ta2NiSe7 probed by orbital magnetoresistance
Jiaming He, Yiran Zhang, Libin Wen +8
Ta2NiSe7 is a quasi-one-dimensional (quasi-1D) transition-metal chalcogenide with Ta and Ni chain structure. An incommensurate charge-density wave (CDW) in this quasi-1D structure…
Nodal surface semimetals: Theory and material realization
Weikang Wu, Ying Liu, Si Li +5
We theoretically study the three-dimensional topological semimetals with nodal surfaces protected by crystalline symmetries. Different from the well-known nodal-point and nodal-lin…
Nonsymmorphic-symmetry-protected hourglass Dirac loop, nodal line, and Dirac point in bulk and monolayer SiTe ( Ta, Nb)
Si Li, Ying Liu, Shan-Shan Wang +5
Nonsymmorphic space group symmetries can generate exotic band-crossings in topological metals and semimetals. Here, based on symmetry analysis and first-principles calculations, we…
Two-dimensional Spin-Orbit Dirac Point in Monolayer HfGeTe
Shan Guan, Ying Liu, Zhi-Ming Yu +3
Dirac points in two-dimensional (2D) materials have been a fascinating subject of research, with graphene as the most prominent example. However, the Dirac points in existing 2D ma…
Type-II nodal loops: theory and material realization
Si Li, Zhi-Ming Yu, Ying Liu +5
Nodal loop appears when two bands, typically one electron-like and one hole-like, are crossing each other linearly along a one-dimensional manifold in the reciprocal space. Here we…
Artificial gravity field, astrophysical analogues, and topological phase transitions in strained topological semimetals
Shan Guan, Zhi-Ming Yu, Ying Liu +5
Effective gravity and gauge fields are emergent properties intrinsic for low-energy quasiparticles in topological semimetals. Here, taking two Dirac semimetals as examples, we demo…
