Soft-phonon and charge-density-wave formation in nematic BaNiAs
S. M. Souliou, T. Lacmann, R. Heid +7
We use diffuse and inelastic x-ray scattering to study the formation of an incommensurate charge-density-wave (I-CDW) in BaNiAs, a candidate system for charge-driven electr…
Absence of temperature-dependent phonon anomalies in Sr2IrO4 and Sr3Ir2O7
K. Sen, R. Heid, S. M. Souliou +8
Following previous works reporting an anomalous behavior of several zone-center optical phonons across the magnetic transition of square lattice iridates Sr2IrO4 and Sr3Ir2O7, we h…
Evidence for nesting driven charge density waves instabilities in a quasi-two-dimensional material: LaAgSb2
Alexeï Bosak, Sofia-Michaela Souliou, Clément Faugeras +6
Since their theoretical prediction by Peierls in the 30s, charge density waves (CDW) have been one of the most commonly encountered electronic phases in low dimensional metallic sy…
Weak localization competes with the quantum oscillations in a natural electronic superlattice: the case of Na(PO)(WO)
Kamil K. Kolincio, Olivier Pérez, Enric Canadell +5
We report an investigation of the combined structural and electronic properties of the bronze Na(PO)(WO). Its low dimensional structure and possibl…
Interplay between electron band-anticrossing and charge-density-wave instabilities
P. D. Grigoriev, A. A. Sinchenko, P. A. Vorobyev +4
Our measurements of the Hall coefficient in rare-earth tritelluride compounds reveal a strong hysteresis between cooling and warming in the low temperature range where a second uni…
Persistent low-energy phonon broadening near the charge order -vector in bilayer cuprate BiSrCaCuO
Yu He, Shan Wu, Yu Song +23
We report a persistent low-energy phonon broadening around r.l.u. along the Cu-O bond direction in the high- cuprate BiSrCaCuO (Bi-2212).…
