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…
Equilibrium and transport properties of constrained systems
Debasish Chaudhuri
Systems under external confinement and constraints often show interesting properties. In this thesis, we study some systems under external confinement. We begin by finding out the…
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…
A numerical renormalization group study of laser induced freezing
Debasish Chaudhuri, Surajit Sengupta
We study the phenomenon of laser induced freezing, within a numerical renormalization scheme which allows explicit comparison with a recent defect mediated melting theory. Precise…
