Crystallization and order-disorder transition of colloidal particles in a drying suspension: a phase field crystal approach
Nirmalendu Ganai, Arnab Saha, Surajit Sengupta
Using a phase field crystal model we study the structure and dynamics of a drop of colloidal suspension during evaporation of the solvent. We model an experimental system where con…
Re-entrant ordering of solute in a colloidal suspension during solvent evaporation
Sumanta Mukherjee, Arnab Saha, Pralay K. Santra +2
We study the phenomenon of self-assembly of silica micro-spheres on a glass plate during evaporation of the solvent from a colloidal suspension. Our experiments unveil an interesti…
Anomalous structural and mechanical properties of solids confined in quasi one dimensional strips
Debasish Chaudhuri, Surajit Sengupta
We show using computer simulations and mean field theory that a system of particles in two dimensions, when confined laterally by a pair of parallel hard walls within a quasi one d…
Novel Fluctuations at a Constrained Liquid-Solid Interface
Abhishek Chaudhuri, Debasish Chaudhuri, Surajit Sengupta
We study the interface between a solid trapped within a bath of liquid by a suitably shaped non-uniform external potential. Such a potential may be constructed using lasers, extern…
Direct test of defect mediated laser induced melting theory for two dimensional solids
Debasish Chaudhuri, Surajit Sengupta
We investigate by direct numerical solution of appropriate renormalization flow equations, the validity of a recent dislocation unbinding theory for laser induced freezing/melting…
Mechanical Failure of a Small and Confined Solid
Debasish Chaudhuri, Surajit Sengupta
Starting from a commensurate triangular thin solid strip, confined within two hard structureless walls, a stretch along its length introduces a rectangular distortion. Beyond a cri…
