Unexpected Effect of Internal Degrees of Freedom on Transverse Phonons in Supercooled Liquids (2006)

Gapinski, J., Meier, G., Kriegs, H., Le Grand, A., Dreyfus, C.

We show experimentally that in a supercooled liquid composed of molecules with internal degrees of freedom the internal modes contribute to the frequency dependent shear viscosity and damping of...

Phonons in colloidal systems (2003)

Penciu,R. S., Kriegs,H., Petekidis,G., Fytas,G., Economou,E. N.

Rich phonon spectra were observed experimentally by Brillouin spectroscopy in liquid, glassy, and crystalline state of colloidal systems of low and high elastic constant contrast. The nature of these...

Acoustic excitations in a self-assembled block copolymer photonic crystal (2003)

Urbas,A. M., Thomas,E. L., Kriegs,H., Fytas,G., Penciu,R. S., Economou,L. N.

High resolution Brillouin light scattering can sensitively detect acoustic phonons in concentrated solutions of a high molecular weight poly(styrene-b-isoprene) symmetric copolymer in toluene. This...

Temperature and pressure dependence of the alpha relaxation and configurational entropy of a prototype glass former (2002)

Comez,L., Fioretto,D., Kriegs,H., Steffen,W.

The alpha relaxation process of the fragile glass former salol is investigated in the T-P domain by means of photon correlation spectroscopy. We find that a time-pressure superposition principle is...

Patkowski,A., Paluch,M., Kriegs,H.

The behavior of the alpha-relaxation process in phenylphthalein-dimethylether (PDE) under high pressure was studied by means of dynamic light scattering-photon correlation spectroscopy (DLS-PCS). The...
