Structural Relaxation and Frequency Dependent Specific Heat in a Supercooled Liquid

Abstract

We have studied the relation between the structural relaxation and the frequency dependent thermal response or the specific heat, $c_p(\omega )$, in a supercooled liquid. The Mode Coupling Theory (MCT) results are used to obtain $c_p(\omega )$ corresponding to different wavevectors. Due to the two-step relaxation process present in the MCT, an extra peak, in addition to the low frequency peak, is predicted in specific heat at high frequency.
