Engineering Spin Splitting in Antiferromagnets by Superatoms with Internal Degree of Freedom
Fengxian Ma, Zeying Zhang, Zhen Gao +4
Superatoms, stable atomic clusters acting as building blocks for new materials, offer unique opportunities due to their rich properties and potential for 2D material assembly. Whil…
Balancing chemical equations: form the perspective of Hilbert basis
Zeying Zhang, Xueqin Zhang, Y. X. Zhao +1
The balancing of chemical equations is a basic problem in chemistry. A commonly employed method is to convert the task to a linear algebra problem, and then solve the null space of…
Hilbert band complexes and their applications
Zeying Zhang, Y. X. Zhao, Yugui Yao +1
The study of band connectivity is a fundamental problem in condensed matter physics. Here, we develop a new method for analyzing band connectivity, which completely solves the outs…
Ideal spin-polarized Weyl-half-semimetal with a single pair of Weyl points in half-Heusler compounds XCrTe (X=K, Rb)
Hongshuang Liu, Jin Cao, Zeying Zhang +3
Realizing ideal Weyl semimetal state with a single pair of Weyl points has been a long-sought goal in the field of topological semimetals. Here, we reveal such a state in the Cr-ba…
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…
