Density dependence of relaxation dynamics in glass formers, and the dependence of their fragility on the softness of inter-particle interactions

Anshul D. S. Parmar, Pallabi Kundu, Srikanth Sastry

Fragility, quantifying the rapidity of variation of relaxation times, is analysed for a series of model glass formers, which differ in the softness of their interparticle interacti…
