Dirac branch-cut modes with relativistic transport
Bofeng Zhu, Chengzhi Ma, Qiang Wang +6
Emergent Dirac fields, exhibiting effective relativistic physics, are most commonly associated with bulk and surface states in materials such as graphene and topological insulators…
Continuum Landau surface states in a non-Hermitian Weyl semimetal
Shuxin Lin, Rimi Banerjee, Zheyu Cheng +3
The surface states of certain topological phases can be linked to a quantum anomaly: the violation of a classical symmetry by a field theory via a non-conserved current. This has b…
Observation of returning Thouless pumping
Zheyu Cheng, Sijie Yue, Yang Long +6
Introduced by David Thouless in 1983, Thouless pumping exemplifies topological properties in topological systems, where the transported charge is quantized by the Chern number. Rec…
Flatbands from Bound States in the Continuum for Orbital Angular Momentum Localization
Weiwei Zhu, Hongyu Zou, Yong Ge +7
A flatband material is a system characterized by energy bands with zero dispersion, allowing for the compact localization of wavefunctions in real space. This compact localization…
Observation of disorder-induced boundary localization
Bing-bing Wang, Zheyu Cheng, Hong-yu Zou +7
Bloch wavefunctions in crystals experience localization within the bulk when disorder is introduced, a phenomenon commonly known as Anderson localization. This effect is considered…
Three-dimensional flat Landau levels in an inhomogeneous acoustic crystal
Zheyu Cheng, Yi-jun Guan, Haoran Xue +7
When electrons moving in two-dimensions (2D) are subjected to a strong uniform magnetic field, they form flat bands called Landau levels, which are the basis for the quantum Hall e…
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…
Projectively enriched symmetry and topology in acoustic crystals
Haoran Xue, Zihao Wang, Yue-Xin Huang +6
Symmetry plays a key role in modern physics, as manifested in the revolutionary topological classification of matter in the past decade. So far, we seem to have a complete theory o…
Observation of topological edge states in thermal diffusion
Hao Hu, Song Han, Yihao Yang +8
The topological band theory predicts that bulk materials with nontrivial topological phases support topological edge states. This phenomenon is universal for various wave systems a…
