Antiferromagnetic Dimers in the Parent Phase of a Correlated Kagome Superconductor
Yifan Wang, Chenchao Xu, Yi Liu +18
Kagome metals are prone to charge-density wave (CDW), magnetic, and superconducting phases, with their flat electronic band conducive for correlated physics. In contrast to the wea…
Phonons reflect dynamic spin-state order in LaCoO
Alsu Ivashko, Taishun Manjo, Maximilian Kauth +17
We investigate lattice dynamics in LaCoO using inelastic neutron and x-ray scattering over $T = 2\mbox{-}650\,\mathrm{K}$, spanning the spin-state crossover at $T_{1} \approx 1…
Incipient ionic conductors: Ion-constrained lattices achieving superionic-like thermal conductivity by extreme anharmonicity
Yongheng Li, Chunqiu Lu, Bin Wei +7
Phonon liquid-like thermal conduction in the solid state enables superionic conductors to serve as efficient thermoelectric device candidates. While liquid-like motion of ions effe…
Charge Density Fluctuations with Enhanced Superconductivity at the Proposed Nematic Quantum Critical Point
Youzhe Chen, Nathan Giles-Donovan, Jiayu Guo +7
A quantum critical point (QCP) represents a continuous phase transition at absolute zero. At the QCP of an unconventional superconductor, enhanced superconducting transition temper…
