Persistence probability based dynamics and phase diagrams in biased q-voter models
Amit Pradhan, Pratik Mullick, Parongama Sen
Persistence probability in opinion dynamics models estimates the tendency of the agents not to change their initial opinion till the present time. Here we consider two nonlinear q-…
Active-absorbing phase transition and small world behaviour in Ising model on finite addition type networks in two dimensions
Pratik Mullick, Parongama Sen
We consider the ordering dynamics of the Ising model on a square lattice where an additional fixed number of bonds connect any two sites chosen randomly. The total number of shortc…
Effect of bias in a reaction diffusion system in two dimensions
Pratik Mullick, Parongama Sen
We consider a single species reaction diffusion system on a two dimensional lattice where the particles are biased to move towards their nearest neighbours and annihilate as th…
Virtual walks in spin space: a study in a family of two-parameter models
Pratik Mullick, Parongama Sen
We investigate the dynamics of classical spins mapped as walkers in a virtual "spin" space using a generalised two-parameter family of spin models characterized by parameters a…
Zero temperature coarsening in Ising model with asymmetric second neighbour interaction in two dimensions
Pratik Mullick, Parongama Sen
We consider the zero temperature coarsening in the Ising model in two dimensions where the spins interact within the Moore neighbourhood. The Hamiltonian is given by $H = - \sum_{<…
Minority spin dynamics in non-homogeneous Ising model: diverging timescales and exponents
Pratik Mullick, Parongama Sen
We investigate the dynamical behaviour of the Ising model under a zero temperature quench with the initial fraction of up spins . In one dimension, the known results…
