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…
Pseudomagnetic suppression of non-Hermitian skin effect
Hau Tian Teo, Subhaskar Mandal, Yang Long +2
It has recently been shown that the non-Hermitian skin effect can be suppressed by magnetic fields. In this work, using a two-dimensional tight-binding lattice, we demonstrate that…
Localization of chiral edge states by the non-Hermitian skin effect
Gui-Geng Liu, Subhaskar Mandal, Peiheng Zhou +11
Quantum Hall systems host chiral edge states extending along the one-dimensional boundary of any two-dimensional sample. In solid state materials, the edge states serve as perfectl…
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…
Topological acoustics
Haoran Xue, Yihao Yang, Baile Zhang
Topological acoustics is an emerging field that lies at the intersection of condensed matter physics, mechanical structural design and acoustics engineering. It explores the design…
Free-electron Brewster radiation
Ruoxi Chen, Jialin Chen, Zheng Gong +7
Free-electron radiation offers an enticing route to create light emission at arbitrary spectral regime. However, this type of light emission is generally weak, which is intrinsical…
