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…
Second-Order Real Nodal-Line Semimetal in Three-Dimensional Graphdiyne
Cong Chen, Xu-Tao Zeng, Ziyu Chen +3
Real topological phases featuring real Chern numbers and second-order boundary modes have been a focus of current research, but finding their material realization remains a challen…
Graphyne as a second-order and real Chern topological insulator in two dimensions
Cong Chen, Weikang Wu, Zhi-Ming Yu +4
Higher-order topological phases and real topological phases are two emerging topics in topological states of matter, which have been attracting considerable research interest. Howe…
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…
Ferromagnetic Dirac-Nodal Semimetal Phase of Stretched Chromium Dioxide
R. Wang, J. Z. Zhao, Y. J. Jin +4
We show by first-principles calculations that the Dirac nodal-line semimetal phase can co-exist with the ferromagnetic order at room temperature in chromium dioxide, a widely used…
