Terminal stage of highly viscous flow

U. Buchenau

The shear misfit model for the highly viscous flow is based upon a theoretical prediction for its terminal stage in terms of irreversible Eshelby relaxations in the five-dimensiona…

Hydrogen bond dynamics at the glass transition

U. Buchenau

The glass transition in hydrogen-bonded glass formers differs from the glass transition in other glass formers. The Eshelby rearrangements of the highly viscous flow are superimpos…

A note on Kauzmann's paradox

U. Buchenau

The rapid structural and vibrational entropy decrease with decreasing temperature in undercooled liquids is explained in terms of the disappearance of local structural instabilitie…

Sound absorption in glasses

U. Buchenau, G. D'Angelo, G. Carini +2

The paper presents a description of the sound wave absorption in glasses, from the lowest temperatures up to the glass transition, in terms of three compatible phenomenological mod…

Strain field of soft modes in glasses

U. Buchenau

The strain field surrounding the center of low frequency vibrational modes is analyzed for numerically created binary glasses with a 1/r^10 repulsive interatomic potential. Outside…

Theory of the highly viscous flow

U. Buchenau

The recent theoretical treatment of irreversible jumps between inherent states with a constant density in shear space is extended to a full theory, attributing the shear relaxation…
