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-…
Diffusive-to-Ballistic transition in a Persistent Random Walk
Amit Pradhan, Reshmi Roy, Purusattam Ray
We study persistent random walk with time dependent velocity reversal probabilities and identify a criterion for a non-equilibrium dynamical transition. As a representative example…
Generalized BChS Model with Group Interactions: Shift in the Critical Point and Mean-Field Ising Universality
Amit Pradhan
We introduce a generalized version of the Biswas-Chatterjee-Sen (BChS) model \cite{Biswas} with group interactions of size , extending the original pairwise interaction dynamics…
Virtual walks in the Ising model: finite time scaling
Amit Pradhan, Parongama Sen, Sagnik Seth
The dynamics of the spins in the Ising model are analyzed using a virtual walk scenario. The system is quenched from a very high temperature to a lower one using the Glauber scheme…
