Phononic origin of the infrared dielectric properties of RE₂O₃ (RE = Y, Gd, H...
Understanding the phononic origin of the infrared dielectric properties of yttria (Y₂O₃) and other rare-earth sesquioxides (RE₂O₃) is a fundamental task in the search of... -
The effect of a vanishing pseudogap on the magnetic excitations in overdoped ...
One of the major issues in high temperature superconductivity is the nature of the so called pseudogap phase. A related question is whether the pseudogap controls the evolution... -
Excitations, BEC, and partially ordered states of liquid 4He in disorder
We propose measurements of the elementary phonon-roton (p-r) excitations of liquid 4He confined in porous MCM-41 (45 Å pore diameter) at wave vectors Q ¿ beyond the roton¿, 2.4... -
A µSR study of the charge density wave superconductor CuxTiSe2.
Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and... -
Lattice vibrations of hydrogen impurities in a solid neon matrix
In recent incoherent inelastic neutron scattering experiments we have shown that the anharmonic single-particle dynamics of H2 can be measured with high precision in quantum... -
The collective spin excitations in the electron-doped superconductor BaFe2-xC...
We propose to measure the collective spin excitations over a wide energy range in BaFe2-xCoxAs2 (x=0.22). This compound is one of the FeAs based superconductors which have... -
Giant magneto-elastic interactions and changes in the phonon spectrum of CoMnSi
Neutrons are almost never used to examine the role of phonons in materials with large magnetocaloric effects, despite the large magneto-elastic coupling often exhibited by them.... -
Study of the phonon confinement in novel thermoelectric materials
The material design challenge in thermoelectric materials is to find the materials where the conduction of heat is low and the electrical conductivity is high. It was recently... -
Modifications to the phonon spectrum of nanocomposite thermoelectrics
Here we propose to use the superior energy resolution of OSIRIS to measure the phonon desnity of states (PDOS) of both nanocomposite and bulk thermoelectric alloys of Si1-xGex.... -
Spin-phonon coupling in heavy fermion CeAuAl3 and CeCuAl3 compounds
To understand this novel ground state of CeCuAl3, we have carried out low and high-energies inelastic neutron scattering (INS) measurements using the IRIS and HET spectrometers.... -

Data for: Lattice dynamics and ultrafast energy flow between electrons, spins...
The ultrafast dynamics of magnetic order in a ferromagnet are governed by the interplay between electronic, magnetic and lattice degrees of freedom. In order to obtain a...
