Charge density wave in a band insulator
Md Shafayat Hossain, Wenhao Liu, Yuqi Zhang +20
Charge density wave (CDW) implies a periodic modulation of the charge density. Typically observed in metallic systems, CDWs arise from Fermi surface instabilities, resulting in the…
Performance of Planar XYZ and XZZX Codes under Homogeneous and Spatially Nonuniform Noise
Zhiwei Wang, Liqi Wang
The minimum-weight perfect matching (MWPM) decoder is a standard decoding strategy for surface codes, but its performance can degrade considerably under biased noise. In this work,…
Anomalous Low-temperature Magnetotransport in Kagome Metal CsCrSb under Pressure
Zikai Zhou, Wenyan Wang, Deng Hu +5
As a unique kagome superconductor displaying clear signatures of strong electronic correlations, CsCrSb has drawn much attention. Its rich temperature-pressure phase diagra…
Extreme Terahertz Nonlinear Phononics by Coherence-Imprinted Control of Hybrid Order
Liang Luo, Avinash Khatri, Martin Mootz +12
Coherent control of quantum materials has progressed along two major fronts: nonlinear phononics, which reshapes lattices to induce emergent states, and Floquet engineering, which…
Type-I and Type-II Saddle Points and a Topological Flat Band in a Bi-Pyrochlore Superconductor CsBi2
Yusei Morita, Yongkai Li, Yu-Hao Wei +12
The divergence of the electron density of states (DOS) plays an important role in enhancing many-body interactions and inducing various quantum phases in low-dimensional systems. H…
Direct Visualization of Room-temperature Stair-stepped Quantum Spin Hall States in Bi4Br4
Zhiqiang Hu, Yuqi Zhang, Yuyang Wang +7
Topological insulators host exotic quantum phenomena such as the quantum spin Hall (QSH) effect, which enables dissipationless one-dimensional edge conduction. Realizing such state…
Ultrafast μeV-Precision Bandgap Engineering in Low-Dimensional Topological Insulators
Peng Tan, Yuantao Chen, Yuqi Zhang +14
Precise and ultrafast control of electronic band structures is a central challenge for advancing quantum functional materials and devices. Conventional approaches--such as chemical…
Ultrafast symmetry modulation and induced magnetic excitation in the Kagome metal RbV3Sb5
Mengxue Guan, Xiaodong Zhou, Jingyi Duan +8
Light-matter interaction in frustrated Kagome metals enables access to hidden quantum states, yet the microscopic origin of symmetry breaking under ultrafast excitation remains elu…
Topological surface states in γ-PtBi evidenced by scanning tunneling microscopy
Yunkai Guo, Jingming Yan, Wen-Han Dong +11
For the application of topological materials, the specific location of their topological surface states with respect to the Fermi level are important. γ-PtBi2 has been demonstrated…
Shear-resistant topology in quasi one-dimensional van der Waals material BiBr
Jonathan K. Hofmann, Hoyeon Jeon, Saban M. Hus +10
BiBr is a prototypical quasi one-dimensional (1D) material in which covalently bonded bismuth bromide chains are arranged in parallel, side-by-side and layer-by-layer, with…
Discovery of terahertz-frequency orbitally-coupled magnons in a kagome ferromagnet
Mengqian Che, Weizhao Chen, Maoyuan Wang +12
In ferromagnetic materials, magnons - quanta of spin waves - typically resonate in the gigahertz range. Beyond conventional magnons, while theoretical studies have predicted magnon…
