Electrostriction effects on competing transition states in supercritical fluoroform
, 2002 A compressible continuum model for supercritical fluoroform is used to model enantiomeric selectivities measured experimentally by Jessop et al. While oversimplified models, which exaggerate the importance of the electrostriction effect, do produce a non-

On electrostriction of a granular superconductor [PDF]
Solid State Communications, 1998 Zero-temperature field-induced polarization, supercurrent density, and the related electrostriction (ES) of a granular superconductor are calculated within a model of 3D Josephson junction arrays. Both the "bulk-modulus-driven ES" (the change of the sample's volume in the free energy upon the applied stress) and the "change-of-phase ES" (due to the ...
