Breakdown of material-time scaling in the microscopic dynamics of metallic glasses
Till Böhmer, Jie Shen, Jan Philipp Gabriel +6
Physical aging in glasses is often described using the concept of material time, which assumes the underlying relaxation mechanism to remain the same as in equilibrium, but with a…
Ultra-broadband and time-resolved depolarized dynamic light scattering for probing molecular dynamics in supercooled liquids and glasses
Till Böhmer, Rolf Zeißler, Robin Schwäch +3
Dynamic light scattering (DLS) is a versatile technique for probing microscopic dynamics in soft condensed matter. However, applying DLS to supercooled molecular liquids and glasse…
Linear-limit aging times of three monoalcohols
Jan Philipp Gabriel, Jeppe C. Dyre, Tina Hecksher
This paper presents data for the physical aging of the three monoalcohols 2-ethyl-1-butanol, 5-methyl-2-hexanol, and 1-phenyl-1-propanol. Aging is studied by monitoring the dielect…
On the Spectral Shape of the Structural Relaxation in Deeply Supercooled Liquids
Till Böhmer, Florian Pabst, Jan Gabriel +2
Structural relaxation in deeply supercooled liquids is non-exponential. In susceptibility representation, , the spectral shape of the structural relaxation is…
Dipolar order controls dielectric response of glass-forming liquids
Till Böhmer, Florian Pabst, Jan P. Gabriel +1
The dielectric response of liquids reflects both, reorientation of single molecular dipoles and collective modes, i.e., dipolar cross-correlations. A recent theory predicts the lat…
Local and Global Expansivity in Water
Jan Philipp Gabriel, Robin Horstmann, Martin Tress
The supra-molecular structure of a liquid is strongly connected to its dynamics which in turn controls macroscopic properties such as viscosity. Consequently, detailed knowledge ab…
Time reversibility during the ageing of materials
Till Böhmer, Jan P. Gabriel, Lorenzo Costigliola +4
Physical ageing is the generic term for irreversible processes in glassy materials resulting from molecular rearrangements. One formalism for describing such ageing processes invol…
Glassy Dynamics in Polyalcohols: Intermolecular Simplicity vs. Intramolecular Complexity
Till Böhmer, Jan Philipp Gabriel, Rolf Zeißler +2
Using depolarized light scattering, we have recently shown that structural relaxation in a broad range of supercooled liquids follows, to good approximation, a generic line shape w…
Intra- and Intermolecular Inhomogeneities in the Course of Glassy Densification of Polyalcohols
Jan Philipp Gabriel, Martin Tress, Wilhelm Kossack +2
To test basic assumptions inherent to most theories of molecular liquids and glasses, Infrared spectroscopy is carried out on short polyalcohols at temperatures ranging from far ab…
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…
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…
Local dielectric response in 1-propanol: -relaxation versus relaxation of mesoscale structures
Peter Weigl, Daniel Koestel, Florian Pabst +3
The dielectric Debye relaxation in monohydroxy alcohols has been subject of long-standing scientific interest and is presently believed to arise from the relaxation of transiently…
The Influence of Molecular Architecture on the Dynamics of H-Bonded Supramolecular Structures in Phenyl-Propanols
Till Böhmer, Jan Gabriel, Timo Richter +2
The relaxation behaviour of monohydroxy alcohols (monoalcohols) in broadband dielectric spectroscopy (BDS) is usually dominated by the Debye process. This process is regarded as a…
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…
