Universal Structural Relaxation in Supercooled Liquids
Florian Pabst, Jan Gabriel, Till Böhmer +6
One of the hallmarks of molecular dynamics in deeply supercooled liquids is the non-exponential character of the relaxation functions. It has been a long standing issue if 'univers…
Temperature dependence of the static permittivity andintegral formula for the Kirkwood correlation factor ofsimple polar fluids
Pierre-Michel Déjardin, Florian Pabst, Yann Cornaton +4
An exact integral formula for the Kirkwood correlation factor of isotropic polar fluids is derived from the equilibrium averaged rotational Dean equation, which as compared t…
Dipole-dipole correlations and the Debye process in the dielectric response of non-associating glass forming liquids
Florian Pabst, Andreas Helbling, Jan Gabriel +2
The non-exponential shape of the -process observed in supercooled liquids is considered as one of the hallmarks of glassy dynamics and has thus been under study for decades, but…
Intermolecular Cross-Correlations in the Dielectric Response of Glycerol
Jan Philipp Gabriel, Parvaneh Zourchang, Florian Pabst +4
We suggest a way to disentangle self- from cross-correlation contributions in the dielectric spectra of glycerol. Recently it was demonstrated for monohydroxy alcohols that a detai…
On the Nature of the Debye-Process in Monohydroxy Alcohols: 5-Methyl-2-Hexanol Investigated by Depolarized Light Scattering and Dielectric Spectroscopy
Jan Gabriel, Florian Pabst, Andreas Helbling +2
The slow Debye-like relaxation in the dielectric spectra of monohydroxy alcohols is a matter of long standing debate. In the present work, we probe reorientational dynamics of 5-me…
