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…
Enhanced thermodynamic efficiency in time asymmetric ratchets
Raishma Krishnan, Soumen Roy, A. M. Jayannavar
The energetic efficiency of an overdamped Brownian particle in a saw tooth potential in the presence of time asymmetric forcing is studied in the adiabatic limit. An error made in…
Is small-world network disordered?
Soumen Roy, Somendra M. Bhattacharjee
Recent renormalization group results predict non self averaging behaviour at criticality for relevant disorder. However, we find strong self averaging(SA) behaviour in the critical…
