Acoustics and metastable liquids

Liquid limits: glass transition and liquid-gas spinodal boundaries of metastable liquids.

The liquid-gas spinodal and the glass transition define ultimate boundaries beyond which substances cannot exist as (stable or metastable) liquids. The relation between these limits is analyzed via computer simulations of a model liquid. The results obtained indicate that the liquid-gas spinodal and the glass transition lines intersect at a finite temperature, implying a glass-gas mechanical in...

Metastable states as a key to the dynamics of supercooled liquids

Computer simulations of a model glass-forming system are presented, which study the correlation between the dynamics in real space and the topography of the potential energy landscape. This analysis clearly reveals that in the supercooled regime the dynamics is strongly influenced by the presence of deep valleys in the energy landscape, corresponding to long-lived metastable amorphous states. W...

Curvature e ect on the physical boundary of metastable states in liquids

The physical boundary of metastable states, the kinetic spinodal, is introduced as a locus where the lifetime of metastable state becomes shorter than a relaxation time to local equilibrium. The theory does not contain any adjustable parameters. If the surface tension is known, the kinetic spinodal is completely determined by the equation of state only. The curvature e ect on the surface tensio...

Session 5pMU Musical Acoustics and Structural Acoustics and Vibration: Computational Methods in Musical Acoustics II

Real-time auralization of physical models has attracted vivid interest over the last years. This is mainly due to the rising computational capabilities of personal computers and the accessibility of specialized (external) accelerating hardware, like GPGPUs (generalpurpose graphics processing units) or FPGAs (field programmable gate arrays). In this work, an extended framework of real-time physi...
