Observation of coherently modulated thermal phonon band and lifetime in superlattice
Yuxuan Liao, Hiroshi Uchiyama, Naomi Nagai +12
Manipulating phonon band structures through wave interference in artificial periodic nanostructures is of fundamental interest and forms the foundation of phonon band engineering.…
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…
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…
First Order Preemptive Ising-nematic Transition in KFeAgTe
N. Giles-Donovan, Y. Chen, H. Fukui +11
Employing inelastic X-ray scattering and neutron scattering techniques, we observed nematic and magnetic phase transitions with distinct characters in KFeAgTe$_{1…
