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…
A Posterior MWPM Decoding Boosts the XYZ Planar Code
Zhiwei Wang, Liqi Wang
The minimum-weight perfect matching (MWPM) decoder is a standard decoding strategy for surface codes, but its performance degrades considerably under biased noise. In this paper, a…
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…
