Dielectric and thermal relaxation in the energy landscape (2006)
Buchenau, U., Zorn, R., Ohl, M., Wischnewski, A.
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 interaction between...

A new interpretation of dielectric data in molecular glass formers (2005)
Buchenau, U., Ohl, M., Wischnewski, A.
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, but still a decade...
Neutron scattering evidence on the nature of the boson peak (2004)
Buchenau, U., Wischnewski, A., Ohl, M., Fabiani, E.
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 matrix, but a slow...
Fragility and compressibility at the glass transition (2004)
Isothermal compressibilities and Brillouin sound velocities from the literature allow to separate the compressibility at the glass transition into a high-frequency vibrational and a low-frequency...
