Dynamical Scaling In Two Dimensional Quenched Uniaxial Nematic Liquid Crystals
Subhrajit Dutta, Soumen Kumar Roy
The phase ordering kinetics of the two-dimensional uniaxial nematic has been studied using a Cell Dynamic Scheme. The system after quench from T=infinity was found to scale dynamic…

Phase Transitions In Two Planar Lattice Models And Topological Defects: A Monte Carlo Study
Subhrajit Dutta, Soumen Kumar Roy
Monte Carlo simulation has been performed in the planar P(_{2}) and P(_{4}) models to investigate the effects of the suppression of topological defects on the phase transition exhi…

Electrostatic acoustic modes in a self-gravitating complex plasma with variable charge impurities
Amar P Misra, K. Roy Chowdhury, A. Roy Chowdhury
A linear theory of dust acoustic (DA) and dust ion-acoustic (DIA) waves in a self-gravitating collisional dusty plasma contaminated by variable-charge impurities is presented for a…
