From the imaginary parts of the isobaric specific heat, isothermal bulk modulus, and isobaric thermal expansion coefficient, we define a quantity $\\Lambda_{Tp}(\\omega)$ with the property that $\\Lambda_{Tp}(\\omega)=1$ is equivalent to having a one-parameter description of the linear thermo-visco-elastic response. This provides an alternative to the well-known criterion based on the Prigogine-Defay ratio.", "revisions": [ { "version": "v1", "updated": "2004-05-31T19:38:51.000Z" } ], "analyses": { "keywords": [ "glass-forming liquid", "single-frequency test", "one-parameter models", "frequency-dependent linear thermo-visco-elastic response functions", "isobaric thermal expansion coefficient" ], "tags": [ "journal article" ], "publication": { "publisher": "AIP", "journal": "J.
