Reply to “Comment on ‘Correlation between configurational entropy and structural relaxation time in glass-forming liquids’ ”

Abstract

In this Reply we show that contrary to the statements of Goldstein, the empirical function we proposed [D. Prevosto, M. Lucchesi, S. Capaccioli, R. Casalini, and P. A. Rolla, Phys. Rev. B 67, 174202 (2003)] for the pressure and temperature dependencies of the configurational entropy is mathematically and physically valid. Specifically we demonstrate that the condition of equal second derivatives, necessary for the configurational entropy to be a function of state, has physically reasonable solutions without the necessity of imposing implausible constraints.
