Interplay between Quantum Metric and Hybridized Collective Mode in Flat-Band Superfluids
Yi Liu, Mingyan Wang, Penghui Hu +1
We investigate collective excitations in flat-band superfluids by incorporating the coupled dynamics of pairing (phase and amplitude) and density fluctuations. We demonstrate that…
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…
Frieze charge-stripes in a correlated kagome superconductor CsCrSb
Siyu Cheng, Keyu Zeng, Yi Liu +4
Kagome metals have developed into a vibrant playground for materials physics, where geometric frustration, electronic correlations and band topology come together to create a varie…
Controlling an altermagnetic spin density wave in the kagome magnet CsCr3Sb5
Zihao Huang, Chenchao Xu, Yande Que +8
The interplay of charge and spin orders lies at the heart of correlated electron physics and plays a critical role in the emergence of unconventional quantum phases. Kagome magnets…
Charge density wave with suppressed long-range structural modulation in canted antiferromagnetic kagome FeGe
Chenfei Shi, Wenchang Hou, Hanbin Deng +30
Kagome lattice can host abundant exotic quantum states such as superconductivity and charge density wave (CDW). Recently, successive orders of A-type antiferromagnetism (AFM), CDW…
