Flux-Mediated Correspondence Between Real- and Momentum-Space Nonsymmorphicity
Z. Y. Chen, Y. X. Zhao
Momentum-space nonsymmorphic symmetries have recently attracted significant interest in both artificial and condensed-matter crystals, whereas real-space nonsymmorphic symmetries h…
Applications of Superconductor-Normal Metal Interfaces
S. A. Lemziakov, B. Karimi, S. Nakamura +8
The importance and non-trivial properties of superconductor normal metal interfaces was discovered by Alexander Fyodorovich Andreev more than 60 years ago. Only much later these hy…
Projective symmetry determined topology in flux Su-Schrieffer-Heeger model
Gang Jiang, Z. Y. Chen, S. J. Yue +4
In the field of symmetry-protected topological phases, a common wisdom is that the symmetries fix the topological classifications, but they alone cannot determine whether a system…
Projective Spacetime Symmetry of Spacetime Crystals
Zheng Zhang, Z. Y. Chen, Y. X. Zhao
Wigner's seminal work on the Poincaré group revealed one of the fundamental principles of quantum theory: symmetry groups are projectively represented. The condensed-matter counter…
General Theory of Momentum-Space Nonsymmorphic Symmetry
Chen Zhang, Z. Y. Chen, Zheng Zhang +1
As a fundamental concept of all crystals, space groups are partitioned into symmorphic groups and nonsymmorphic groups. Each nonsymmorphic group contains glide reflections or screw…
Stiefel-Whitney topological charges in a three-dimensional acoustic nodal-line crystal
Haoran Xue, Z. Y. Chen, Zheyu Cheng +4
Band topology of materials describes the extent Bloch wavefunctions are twisted in momentum space. Such descriptions rely on a set of topological invariants, generally referred to…
Classification of time-reversal-invariant crystals with gauge structures
Z. Y. Chen, Zheng Zhang, Shengyuan A. Yang +1
A peculiar feature of quantum states is that they may embody so-called projective representations of symmetries rather than ordinary representations. Projective representations of…
Brillouin Klein Bottle From Artificial Gauge Fields
Z. Y. Chen, Shengyuan A. Yang, Y. X. Zhao
A Brillouin zone is the unit for the momentum space of a crystal. It is topologically a torus, and distinguishing whether a set of wave functions over the Brillouin torus can be sm…
Magnetic Properties and Electronic Configurations of Mn Ions in the Diluted Magnetic Semiconductor BaK(ZnMn)As Studied by X-ray Magnetic Circular Dichroism and Resonant Inelastic X-ray Scattering
H. Suzuki, G. Q. Zhao, J. Okamoto +18
The magnetic properties and the electronic excitations of the new diluted magnetic semiconductor BaK(ZnMn)As have been studied by x-ray magn…
Ultralow-loss domain wall motion driven by magnetocrystalline anisotropy gradient in antiferromagnetic nanowire
D. L. Wen, Z. Y. Chen, W. H. Li +7
Searching for new methods controlling antiferromagnetic (AFM) domain wall is one of the most important issues for AFM spintronic device operation. In this work, we study theoretica…
