Heating a solid sphere at the surface induces mechanical stresses inside the sphere. If a finite amount of heat is supplied, the stresses gradually disappear as temperature becomes homogeneous throughout the sphere. We show that before this happens, there is a temporary lowering of pressure and density in the interior of the sphere, inducing a transient lowering of the temperature here. For ordinary solids this effect is small because c_p is almost equal to c_V. For fluent liquids the effect is…

Dynamics between the fishbone instability and nonlocal transient transport in HL-2A NBI plasmas
Understanding of nonlocal electron heat transport is of key importance for current magnetic confinement fusion research. Global nonlocal response presents a fundamental challenge to the standard
Time-scale ordering in hydrogen- and van der Waals-bonded liquids.
Findings indicate a general relation between the time scales of different response functions and, as inter-molecular interactions apparently play a subordinate role, suggest a rather generic nature of the process of structural relaxation.


Frequency-dependent specific heat from thermal effusion in spherical geometry.
A method of measuring the frequency-dependent specific heat at the glass transition applied to 5-polyphenyl-4-ether which has highest at a frequency where the thermal diffusion length is comparable to the radius of the heat generator.

In liquids the molecular configuration is a function of temperature. If in a given substance super-cooling of the liquid is possible to such a low temperature—the ‘transformation temperature’
Conventional methods fail to measure cp (omega) of glass-forming liquids.
By solving the full one-dimensional thermoviscoelastic problem analytically it is shown that, because of thermal expansion and the fact that mechanical stresses relax on the same time scale as the enthalpy relaxes, the plane thermal-wave method does not measure the isobaric frequency-dependent specific heat c{p}(omega) .

Single-order-parameter description of glass-forming liquids: a one-frequency test.
Generalizations to other cases of thermodynamic control parameters than temperature and pressure are presented and a "linear dynamic Prigogine-Defay ratio" LambdaTp(omega) is defined with the property that if LambdaS(omeg)=1 at one frequency, then LambdaP(omegas) is unity at all frequencies.
