Dielectric and thermal relaxation in the energy landscape
U. Buchenau, R. Zorn, M. Ohl +1
We derive an energy landscape interpretation of dielectric relaxation times in undercooled liquids, comparing it to the traditional Debye and Gemant-DiMarzio-Bishop pictures. The i…
A new interpretation of dielectric data in molecular glass formers
U. Buchenau, M. Ohl, A. Wischnewski
Literature dielectric data of glycerol, propylene carbonate and ortho-terphenyl (OTP) show that the measured dielectric relaxation is a decade faster than the Debye expectation, bu…
Neutron scattering evidence on the nature of the boson peak
U. Buchenau, A. Wischnewski, M. Ohl +1
A close inspection of neutron spectra of glass formers in the frequency region above the boson peak does not show the constant eigenvalue density expected for a random dynamical ma…
Magnetic neutron scattering study of YVO3: Evidence for an orbital Peierls state
C. Ulrich, G. Khaliullin, J. Sirker +5
Neutron spectroscopy has revealed a highly unusual magnetic structure and dynamics in YVO, an insulating pseudocubic perovskite that undergoes a series of temperature induced p…
