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…
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…
Elastic Valley Spin Controlled Chiral Coupling in Topological Valley Phononic Crystals
Jinfeng Zhao, Chenwen Yang, Weitao Yuan +6
Distinct from the phononic valley pseudo-spin, the real physical spin of elastic waves adds a novel tool-kit capable of envisaging the valley-spin physics of topological valley pho…
Quantum Spin of Elastic Wave
Yang Long, Jie Ren, Hong Chen
Unveiling intrinsic spins of propagating waves usually offers people a fundamental understanding of the geometrical and topological properties of waves from classical to quantum as…
Photonic Spin Hall Effect in Waveguides Composed of Two Types of Single-Negative Metamaterials
Zhiwei Guo, Haitao Jiang, Yang Long +4
The polarization controlled optical signal routing has many important applications in photonics such as polarization beam splitter. By using two-dimensional transmission lines with…
Asymmetric Nonlinear System is Not sufficient for Non-Reciprocal Quantum Wave Diode
Gaomin Wu, Yang Long, Jie Ren
We demonstrate symmetric wave propagations in asymmetric nonlinear quantum systems. By solving the nonlinear Schördinger equation, we first analytically prove the existence of symm…
