Complex Networks: effect of subtle changes in nature of randomness
Sanchari Goswami, Soham Biswas, Parongama Sen
In two different classes of network models, namely, the Watts Strogatz type and the Euclidean type, subtle changes have been introduced in the randomness. In the Watts Strogatz typ…
Phase transitions in a two parameter model of opinion dynamics with random kinetic exchanges
Parongama Sen
Recently, a model of opinion formation with kinetic exchanges has been proposed in which a spontaneous symmetry breaking transition was reported [M. Lallouache et al, Phys. Rev. E,…
Agent dynamics in kinetic models of wealth exchange
Arnab Chatterjee, Parongama Sen
We study the dynamics of individual agents in some kinetic models of wealth exchange, particularly, the models with savings. For the model with uniform savings, agents perform simp…
Novel ballistic to diffusive crossover in the dynamics of a one dimensional Ising model with variable range of interaction
Soham Biswas, Parongama Sen
The idea that the dynamics of a spin is determined by the size of its neighbouring domains was recently introduced (S. Biswas and P. Sen, Phys. Rev. E {\bf 80}, 027101 (2009)) in a…
Quantum Persistence: A Random Walk Scenario
Sanchari Goswami, Parongama Sen, Arnab Das
In this paper we extend the concept of persistence, well defined for classical stochastic dynamics, to the context of quantum dynamics. We demonstrate the idea via quantum random w…
