Phys. Rev. E 62, 1670–1673 (2000)Elastic behavior in a supercooled liquid: Analysis of viscoelasticity using an extended mode coupling modelReceived 12 July 1999; revised 28 March 2000; published in the issue dated August 2000 The transverse current correlations are analyzed using the formalism of extended mode coupling theory. The undercooled liquid can sustain shear waves up to a minimum wave number. With the increase of density this wave number decreases, indicating a growing length scale that is related to the dynamics. The speed of the propagating shear waves goes to zero approaching a critical wave number. The maximum wavelength shows an initial enhancement approaching the mode coupling transition and finally grows at a slower rate as the sharp transition is cut off. © 2000 The American Physical Society URL:
