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…
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…
Acoustic phonon softening and lattice instability driven by on-site - hybridization in CeCoSi
Takeshi Matsumura, Takumi Hasegawa, Ryuma Nakajima +5
Soft phonon modes in tetragonal CeCoSi, which undergoes a structural transition at K followed by antiferromagnetic order at K, have been investigated us…
Soft Mode Origin of Charge Ordering in Superconducting Kagome CsVSb
Philippa Helen McGuinness, Fabian Henssler, Manex Alkorta +12
Charge-density-wave (CDW) order and superconductivity coexist in the kagome metals AVSb (A=K, Cs, Rb), raising fundamental questions about the mechanisms driving their inte…
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…
Hybridization of lattice and charge order excitations in a superconducting cuprate
S. M. Souliou, D. Ishikawa, R. Heid +9
The ubiquitous tendency of superconducting cuprates to form charge density waves (CDWs) has reignited interest in the nature of their electron-phonon interaction and its role in sh…
Absence of Acoustic Phonon Anomaly in a Kagome Metal with Short-ranged Structural Modulation
Weiliang Yao, Supeng Liu, Zifan Xu +9
Kagome lattice VSb ( = K, Rb, and Cs) superconductors without magnetism from vanadium -electrons are intriguing because they have a novel charge density wave (CDW)…
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…
Nematic correlation length in iron-based superconductors probed by inelastic x-ray scattering
A. M. Merritt, F. Weber, J. -P. Castellan +7
Nematicity is ubiquitous in electronic phases of high- superconductors, particularly in the Fe-based systems. We used inelastic x-ray scattering to extract the temperature-dep…

R. G. Burkovsky, A. K. Tagantsev, K. Vaideeswaran +13
We report the results of comprehensive study of the critical dynamics of the prototype perovskite antiferroelectric PbZrO. The combination of inelastic X-ray and diffuse X-ray…
Evidence for a charge collective mode associated with superconductivity in copper oxides from neutron and x-ray scattering measurements of LaSrCuO
S. R. Park, T. Fukuda, A. Hamann +5
In superconducting copper oxides some Cu-O bond-stretching phonons around 70meV show anomalous giant softening and broadening of electronic origin and electronic dispersions have l…
