Is there a true Model-D critical dynamics?
Parongama Sen, Somendra M. Bhattacharjee
We show that non-locality in the conservation of both the order parameter and a noncritical density (model D dynamics) leads to new fixed points for critical dynamics. Depending up…

Short-time scaling in the critical dynamics of an antiferromagnetic Ising system with conserved magnetisation
Parongama Sen, Subinay Dasgupta
We study by Monte Carlo simulations the short-time exponent in an antiferromagnetic Ising system for which the magnetisation is conserved but the sublattice magnetisation (whic…
