Local and global persistence exponents of two quenched continuous lattice spin models
Shyamal Bhar, Subhrajit Dutta, Soumen Kumar Roy
Local and global persistence exponents associated with zero temperature quenched dynamics of two dimensional XY model and three dimensional Heisenberg model have been estimated usi…
Persistence Exponents and Scaling In Two Dimensional XY model and A Nematic Model
Subhrajit Dutta, Soumen Kumar Roy
The persistence exponents associated with the T=0 quenching dynamics of the two dimensional XY model and a two dimensional uniaxial spin nematic model have been evaluated using a n…
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…
