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…
Lattice dynamics and elastic properties of black phosphorus
Eva A. A. Pogna, Alexeï Bosak, Alexandra Chumakova +4
We experimentally determine the lattice dynamics of black phosphorus layered crystals through a combination of x-ray diffuse scattering and inelastic x-ray scattering, and we ratio…
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…
Strain Wave Pathway to Semiconductor-to-Metal Transition revealed by time resolved X-ray powder diffraction
C. Mariette, M. Lorenc, H. Cailleau +42
Thanks to the remarkable developments of ultrafast science, one of today's challenges is to modify material state by controlling with a light pulse the coherent motions that connec…
