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.…
Degenerate Soft Modes and Selective Condensation in BaAlO via Inelastic X-ray Scattering
Yui Ishii, Arisa Yamamoto, Alfred Q. R. Baron +2
BaAlO is a ferroelectric material that exhibits structural quantum criticality through chemical composition tuning. Although theoretical calculations and several diffractio…
Topological Metal-Insulator Transition within the Ferromagnetic state
Ola Kenji Forslund, Chin Shen Ong, Moritz M. Hirschmann +20
A major challenge in condensed matter physics is integrating topological phenomena with correlated electron physics to leverage both types of states for next-generation quantum dev…
Structural and Dynamical Changes in a Gd-Co Metallic Glass by Cryogenic Rejuvenation
Shinya Hosokawa, Jens R. Stellhorn, Laszlo Pusztai +11
To experimentally clarify the changes in structural and dynamic heterogeneities in a metallic glass (MG), Gd65Co35, by rejuvenation with a temperature cycling (cryogenic rejuvenati…
Effect of magnetism on lattice dynamics in SrFeAs as seen via high resolution inelastic x-ray scattering
N. Murai, T. Fukuda, T. Kobayashi +9
Phonon spectra of detwinned {SrFeAs} crystals, as measured by inelastic x-ray scattering, show clear anisotropy accompanying the magneto-structural transition at 200 K. We…
Lattice dynamics and antiferroelectricity in PbZrO tested by X-ray and Brillouin light scattering
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…
Soft and Isotropic Phonons in PrFeAsO_{1-y}
T. Fukuda, A. Q. R. Baron, H. Nakamura +9
Phonons in single crystals of PrFeAsO_{1-y} are investigated using high-resolution inelastic x-ray scattering and ab initio pseudopotential calculations. Extensive measurements of…
Effects of Anisotropic Charge on Transverse Optical Phonons in NiO
H. Uchiyama, S. Tsutsui, A. Q. R Baron
Phonon dispersion of detwinned NiO is measured using inelastic x-ray scattering. It is found that, near the zone center, the energy of the transverse optical phonon mode polarized…
