Low-frequency excitations in a molecular glass: Single-particle dynamics
(American Institute of Physics Publising LLC, 1992)
The low-frequency dynamics of a molecular glass former has been investigated by means of inelastic neutron scattering from a mostly incoherent sample as well as by computer molecular-dynamics simulation. The mode assignments ...
Article
Low-frequency excitations in glassy selenium: A comparison of neutron-scattering and molecular-dynamics results
(American Institute of Physics Publising LLC, 1993)
The microscopic low-frequency dynamics of glassy selenium is investigated by means of the concurrent use of neutron inelastic scattering and computer simulations. A separation of the dynamic response in terms of intra- and ...
Article
Thermal transport in glassy selenium: The role of low-frequency librations
(American Institute of Physics Publising LLC, 1994)
The experimental curves giving the temperature dependence of the thermal conductivity of glassy selenium are considered in detail. The observed behavior can be taken into account quantitatively if the densities of states ...
Article
Correlated atomic motions in glassy selenium
(American Institute of Physics Publising LLC, 1994)
The elastic and total (energy-integrated) structure factors for glassy selenium have been measured by means of neutron spectroscopy within the temperature range 15 KT310 K. The correlated nature of the atomic vibrations ...
