# Reply to Gupta and Kob's Comments on Residual entropy and structural disorder in glass: A two-level model and a review of spatial and ensemble vs. Temporal sampling' [J. Non-Cryst. Solids 360 (2013) 13]''

Abstract : In a recent publication we considered a simple two-level system to clarify the meaning of configurational entropy in glass-forming liquids [1]. For this purpose, we calculated configurational entropy upon irreversible cooling either for conditions mimicking those of calorimetric measurements (S2) or from a purely statistical thermodynamics standpoint (S3). Upon critical scrutiny, however, Gupta and Kob concluded that this model does not imply any new physics and that it is "likely an unphysical artifact" [2]. These comments suggest that our study was prone to misunderstanding. We thus take this opportunity to clarify our position.
