Ab initio electronic conductivity of Fe-bearing post-perovskite
Yihang Peng, Yupei Zhang, Shuai Zhang +5
The electrical conductivity of high-pressure silicates profoundly influences the interior dynamics of rocky planets. Employing the Kubo-Greenwood formalism, we perform ab initio ca…
General ab initio framework for electronic-order-induced lattice-dynamics symmetry breaking
Shuai Zhang, Mengqi Wang, Pan Zhang +1
Conventional \textit{ab initio} approaches are unable to describe phonon time-reversal symmetry () breaking. Here, we develop an \textit{ab initio} framework, grounded…
Comprehensive Study of Phonon Chirality under Symmetry Constraints
Shuai Zhang, Zhiheng Huang, Muchen Du +3
Phonons are quanta of lattice vibrations, and their modes (linear, circular, or stationary) are symmetry-determined. Circularly polarized phonons, possessing nonzero angular moment…
Magnetic order induced chiral phonons in a ferromagnetic Weyl semimetal
Mengqian Che, Jinxuan Liang, Yunpeng Cui +13
Chiral phonons are vibrational modes in a crystal that possess a well-defined handedness or chirality, typically found in materials that lack inversion symmetry. Here we report the…
Understanding chiral charge-density wave by frozen chiral phonon
Shuai Zhang, Kaifa Luo, Tiantian Zhang
Charge density wave (CDW) is discovered within a wide interval in solids, however, its microscopic nature is still not transparent in most realistic materials, and the recently stu…
