Realization of Arbitrary Gauge Fields via Symmetry-Protected Zero Modes
J. X. Dai, Bingbing Wang, Jiangzi Chen +2
Gauge fields are fundamental to modern physics, but prescribed gauge configurations are often difficult to implement in artificial systems. Here, we present a general scheme for re…

Topological classification for chiral symmetry with non-equal sublattices
J. X. Dai, Y. X. Zhao
Chiral symmetry on bipartite lattices with different numbers of -sites and -sites is exceptional in condensed matter, as it gives rise to zero-energy flat bands. Crystalline…

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…
