Quadratic nodal point in a two-dimensional noncollinear antiferromagnet
Xukun Feng, Zeying Zhang, Weikang Wu +2
Quadratic nodal point (QNP) in two dimensions has so far been reported only in nonmagnetic materials and in the absence of spin-orbit coupling. Here, by first-principles calculatio…
Magnetic eight-fold nodal-point and nodal-network fermions in MnB2
Yongheng Ge, Ziming Zhu, Zeying Zhang +3
Realizing topological semimetal states with novel emergent fermions in magnetic materials is a focus of current research. Based on first-principle calculations and symmetry analysi…
Realization of multiple topological states and topological phase transitions in (4,0) carbon nanotube derivatives
Yan Gao, Yu Du, Yun-Yun Bai +5
Exploring various topological states (TS) and topological phase transitions (TPT) has attracted great attention in condensed matter physics. However, so far, there is rarely a typi…
Phonon chirality manipulation mechanism in TMD interlayer-sliding ferroelectrics
Hao Chen, Qianqian Wang, Xukun Feng +2
As an ideal platform, both the theoretical prediction and first experimental verification of chiral phonons are based on transition-metal dichalcogenide materials. The manipulation…
Electrically Controllable Chiral Phonons in Ferroelectric Materials
Hao Chen, Weikang Wu, Kangtai Sun +2
Chiral phonons have attracted increasing attention, as they play important roles in many different systems and processes. However, a method to control phonon chirality by external…
Recipe for single-pair-Weyl-points phonons carrying the same chiral charges
Guangqian Ding, Chengwu Xie, Jingbo Bai +3
Recently, Wang et al. [Phys. Rev. B, 106, 195129 (2022)] challenged a widely held belief in the field of Weyl physics, demonstrating that single-pair-Weyl-points (SP-WPs) can exist…
Magnetic Real Chern Insulator in 2D Metal-Organic Frameworks
Xiaoming Zhang, Tingli He, Ying Liu +6
Real Chern insulators have attracted great interest, but so far, their material realization is limited to nonmagnetic crystals and to systems without spin-orbit coupling. Here, we…
Observation of 2D Weyl Fermion States in Epitaxial Bismuthene
Qiangsheng Lu, P. V. Sreenivasa Reddy, Hoyeon Jeon +20
A two-dimensional (2D) Weyl semimetal featuring a spin-polarized linear band dispersion and a nodal Fermi surface is a new topological phase of matter. It is a solid-state realizat…
Upper bound of a band complex
Si Li, Zeying Zhang, Xukun Feng +5
Band structure for a crystal generally consists of connected components in energy-momentum space, known as band complexes. Here, we explore a fundamental aspect regarding the maxim…
