Unusual Dual Flat Bands and two-dimensional Dirac-node Arc State in Kagome Metal Ni3In2S2
Bo Liang, Yichen Liu, Jie Pang +36
Kagome materials are at the frontier of condensed matter physics. An ideal kagome lattice features only one geometrically frustrated flat band spanning the entire momentum space an…
Superconductivity in Electron Liquids: Precision Many-Body Treatment of Coulomb Interaction
Xiansheng Cai, Tao Wang, Shuai Zhang +5
More than a century after discovery, the theory of conventional superconductivity remains incomplete. While the importance of electron-phonon coupling is understood, a controlled f…
Novel Light Dark Matter Detection with Quantum Parity Detector Using Qubit Arrays
Xuegang Li, Yuxiang Liu, Jing Shu +6
We present the design and the sensitivity reach of the Qubit-based Light Dark Matter detection experiment. We propose the novel two-chip design to reduce signal dissipation, with q…
Spin-Orbit Driven Topological Phases in Kagome Materials
Chi Wu, Tiantian Zhang
Kagome materials have garnered substantial attention owing to their diverse physical phenomena, yet canonical systems such as the AVSb family exhibit poor -type topo…
Comprehensive Study of Phonon Chirality under Symmetry Constraints
Shuai Zhang, Zhiheng Huang, Muchen Du +3
Phonons are quanta of lattice vibrations, and their modes (linear, circular, or stationary) are symmetry-determined. Circularly polarized phonons, possessing nonzero angular moment…
Magnetic order induced chiral phonons in a ferromagnetic Weyl semimetal
Mengqian Che, Jinxuan Liang, Yunpeng Cui +13
Chiral phonons are vibrational modes in a crystal that possess a well-defined handedness or chirality, typically found in materials that lack inversion symmetry. Here we report the…
