Static and dynamic properties of a binary, symmetric mixture of ultrasoft particles in the vicinity of criticality
Tanmay Biswas, Gerhard Kahl, Gaurav P. Shrivastav
We investigate the static and the dynamic properties of an binary, equimolar, size-symmetric mixture of ultrasoft particles in the vicinity of the critical point of the system. Bas…
Phase separation dynamics in a symmetric binary mixture of ultrasoft particles
Tanmay Biswas, Gerhard Kahl, Gaurav P. Shrivastav
Phase separation plays an role in determining the self-assembly of biological and soft-matter systems. In biological systems, liquid-liquid phase separation inside a cell leads to…
Elasticity in crystals with high density of local defects : insights from ultra-soft colloids
Saswati Ganguly, Gaurav Prakash Shrivastav, Shang-Chun Lin +5
In complex crystals close to melting or at finite temperatures, different types of defects are ubiquitous and their role becomes relevant in the mechanical response of these solids…
On the yielding of a defect-rich model crystal under shear: insights from molecular dynamics simulations
Gaurav P. Shrivastav, Gerhard Kahl
Point defects in real crystals at finite temperatures are inevitable. Their dynamics severely influence the mechanical properties of crystals under shear giving rise to nonlinear e…
Flow heterogeneities in supercooled liquids and glasses under shear
Mehrdad Golkia, Gaurav P. Shrivastav, Pinaki Chaudhuri +1
Using extensive non-equilibrium molecular dynamics simulations, we investigate a glassforming binary Lennard-Jones mixture under shear. Both supercooled liquids and glasses are con…
