Time Scales of Fickian Diffusion and the Lifetime of Dynamic Heterogeneity
Rajsekhar Das, Chandan Dasgupta, Smarajit Karmakar
Dynamic heterogeneity, believed to be one of the hallmarks of the dynamics of supercooled liquids, is expected to affect the diffusion of the particles comprising the liquid. We ha…
Geometry-controlled Failure Mechanisms of Amorphous Solids on the Nanoscale
Kallol Paul, Ratul Dasgupta, Jürgen Horbach +1
Amorphous solids, confined on the nano-scale, exhibit a wealth of novel phenomena yet to be explored. In particular, the response of such solids to a mechanical load is not well un…
Signature of Dynamical Heterogeneity in Spatial Correlations of Particle Displacement and its Temporal Evolution in Supercooled Liquids
Indrajit Tah, Smarajit Karmakar
The existence of heterogeneity in the dynamics of supercooled liquids is believed to be one of the hallmarks of the glass transition. Intense research has been carried out in the p…
Particle pinning suppresses spinodal criticality in the shear banding instability
Bhanu Prasad Bhowmik, Smarajit Karmakar, Itamar Procaccia +1
Strained amorphous solids often fail mechanically by creating a shear-band. It had been understood that the shear banding instability is usefully described as crossing a spinodal p…
