Structural relaxation and frequency-dependent specific heat in a supercooled liquid.
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 wave vectors. 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.
