Phys. Rev. E 71, 031204 (2005) [5 pages]Inherent structures and Kauzmann temperature of confined liquidsReceived 20 December 2004; published 21 March 2005 Calculations of the thermodynamical properties of a supercooled liquid confined in a matrix are performed with an inherent structure analysis. The liquid entropy is computed by means of a thermodynamical integration procedure. The contributions to the free energy of the liquid can be decoupled also in confinement in the configurational and the vibrational parts. We show that the vibrational entropy can be calculated in the harmonic approximation as in the bulk case. The Kauzmann temperature of the confined system is estimated from the behavior of the configurational entropy. © 2005 The American Physical Society URL:
