Soliton Staircases and Standing Strain Waves in Confined Colloidal Crystals
Yu-Hang Chui, Surajit Sengupta, Kurt Binder
We show by computer simulation of a two-dimensional crystal confined by corrugated walls that confinement can be used to impose a controllable mesoscopic superstructure of predomin…
Effective interactions and melting of a one dimensional defect lattice within a two-dimensional confined colloidal solid
Yu-Hang Chui, Surajit Sengupta, Ian K. Snook +1
We report Monte Carlo studies of a two-dimensional soft colloidal crystal confined in a strip geometry by parallel walls. The wall-particle interaction has corrugations along the l…
Driven Disordered Polymorphic Solids: Phases and Phase Transitions, Dynamical Coexistence and Peak Effect Anomalies
Ankush Sengupta, Surajit Sengupta, Gautam I. Menon
We study a model for the depinning and driven steady state phases of a solid tuned across a polymorphic phase transition between ground states of triangular and square symmetry. Th…
