Charge-spin dichotomy in the kagome metal CsCr3Sb5

Asato Onishi, Yoichi Kageyama, Cédric Bareille, Sogen Ikegami et autres

Kagome metals host a variety of correlated electronic states, yet the nature of their intertwined orders remains an open question. The recently discovered Cr-based kagome compound CsCr3Sb5 differs from its V-based analogue CsV3Sb5 by exhibiting stronger correlations and a magnetic ground state. …

Spectroscopic Demarcation of Emergent Photons and Spinons in a Dipolar-Octupolar Quantum Spin Liquid

Bin Gao, Zhengbang Zhou, Tingjun Zhang, Andrey A. Podlesnyak et autres

The identification of fractionalized excitations in quantum spin liquids (QSLs) remains a central challenge in condensed matter physics. In dipolar-octupolar (DO) pyrochlores, such as Ce_{2}Zr_{2}O_{7}, the candidate π-flux quantum spin ice (QSI) state is predicted to host both gapless emergent photons and …

Thermoelectric evidence of the electronic structure changes from the charge density wave transition in FeGe

Kaila Jenkins, Yuan Zhu, Dechen Zhang, Guoxin Zheng et autres

Kagome metals provide a material platform for probing new correlated quantum phenomena due to the naturally incorporated linear dispersions, flat bands, and Van Hove singularities in their electronic structures. Among these quantum phenomena is the charge density wave (CDW), or the distortion …

Spin excitation continuum from degenerate states in the mixed ferro-antiferromagnetic exchange system CeMgAl 11 O 19

Bin Gao, Chunxiao Liu, Mason Klemm, Shu Zhang et autres

In the search for unconventional magnetism, exotic quantum states are characterized by a lack of order and a broad spin excitation continuum approaching zero temperature. We study the two-dimensional triangular-lattice effective spin- 1 2 system CeMgAl 11 O 19 , which shows …

Spin excitations and flat electronic bands in a Cr-based kagome superconductor

Zehao Wang, Yucheng Guo, H. Y. Huang, Fang Xi Xie et autres

In the quest for topology- and correlation-driven quantum states, kagome lattice materials have garnered significant interest for their band structures, featuring flat bands (FBs) from the quantum destructive interference of the electronic wavefunction. Tuning an FB to the chemical potential could induce …

Disentangling the intertwined orders in a magnetic kagome metal

Ji Seop Oh, Ananya Biswas, Mason Klemm, Hengxin Tan et autres

Intertwined orders appear when multiple orders are strongly interacting, and kagome metals have emerged as new platforms to explore exotic phases. FeGe has been found to develop a charge density wave (CDW) order within magnetic phase, suggesting an intricate interplay of the …
