By evaluating the configurational entropy, we show that the differences in the dynamics of these systems can be understood in terms of their thermodynamic differences. Analyzing their structure, we demonstrate that differences in pair correlation functions between the two systems, through their contribution to the entropy, dominate the differences in their dynamics, and indeed overestimate the differences. Including the contribution of higher order structural correlations to the entropy leads to smaller estimates for the relaxation times, as well as smaller differences between the two studied systems.</p>1 aBanerjee, Atreyee1 aSengupta, Shiladitya1 aSastry, Srikanth1 aBhattacharyya, Sarika, Maitra  uhttps://library.ncl.res.in/content/role-structure-and-entropy-determining-differences-dynamics-glass-formers-different-0
