Temperature-driven sodium-ion dynamical-to-static crossover in the zig-zag ordered phase of NaCoO
Shangfei Wu, Hengxin Tan, Dong Wu +7
The study combines polarization‑resolved Raman spectroscopy and first‑principles calculations to reveal a temperature‑driven dynamical‑to‑static crossover of sodium ions in Na0.5Co…
Revealing Rotational Symmetry Breaking Charge-density Wave Order in Kagome Superconductor (Rb, K)VSb by Ultrafast Pump-probe Experiments
Qinwen Deng, Hengxin Tan, Brenden R. Ortiz +3
The recently discovered Kagome superconductor AVSb (where A refers to K, Rb, Cs) has stimulated widespread research interest due to its interplay of non-trivial topology an…
Unraveling Intertwined Orders in the Strongly Correlated Kagome Metal CsCr3Sb5
Liangyang Liu, Yidian Li, Hengxin Tan +11
While correlated phenomena of flat bands have been extensively studied in twisted systems, the ordered states that emerge from interactions in the intrinsic flat bands of kagome la…
Observation of Orbital-Selective Dual Modulations in an Anisotropic Antiferromagnetic Kagome Metal TbTi3Bi4
Renjie Zhang, Bocheng Yu, Hengxin Tan +25
Orbital selectivity is pivotal in dictating the phase diagrams of multiorbital systems, with prominent examples including the orbital-selective Mott phase and superconductivity, et…
High temperature surface state in Kondo insulator UBiNi
Christopher Broyles, Xiaohan Wan, Wenting Cheng +16
The resurgence of interest in Kondo insulators has been driven by two major mysteries: the presence of metallic surface states and the observation of quantum oscillations. To furth…
Correlated flat-band physics in a bilayer kagome metal based on compact molecular orbitals
Mounica Mahankali, Fang Xie, Yuan Fang +11
Flat bands, when located close to the Fermi energy, can considerably enhance the influence of electron correlations on the low energy physics in kagome and other frustrated-lattice…
