On the energy landscape at the glass transition
U. Buchenau
A recent hypothesis claims that the glass transition itself, though it is a very pronounced relaxation peak, is no separate relaxation process at all, but is just the breakdown of…
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…
Fragility and compressibility at the glass transition
U. Buchenau, A. Wischnewski
Isothermal compressibilities and Brillouin sound velocities from the literature allow to separate the compressibility at the glass transition into a high-frequency vibrational and…
Comment on: A minimal model for beta relaxation in viscous liquids, by Jeppe C. Dyre and Niels Boye Olsen, Phys. Rev. Lett. 91, 155703 (2003)
U. Buchenau, S. Kahle
This is a comment on the beautiful results of Jeppe Dyre and Niels Boie Olsen, published as a recent Physical Review Letter.
The breakdown of the shear modulus at the glass transition
U. Buchenau
The glass transition is described in terms of thermally activated local structural rearrangements, the secondary relaxations of the glass phase. The interaction between these secon…
Mechanical Relaxation in Glasses and at the Glass Transition
U. Buchenau
The Gilroy-Phillips model of relaxational jumps in asymmetric double-well potentials, developed for the Arrhenius-type secondary relaxations of the glass phase, is extended to a fo…
