Disorder induced phase transition in an opinion dynamics model: results in 2 and 3 dimensions
Sudip Mukherjee, Arnab Chatterjee
We study a model of continuous opinion dynamics with both positive and negative mutual interaction. The model shows a continuous phase transition between a phase with consensus (or…
Phase transitions in Ising model on a Euclidean network
Arnab Chatterjee, Parongama Sen
A one dimensional network on which there are long range bonds at lattice distances with the probability has been taken under consideration. We investiga…
A two-fractal overlap model of earthquakes
Bikas K Chakrabarti, Arnab Chatterjee
We introduce here the two-fractal model of earthquake dynamics. As the fractured surfaces have self-affine properties, we consider the solid-solid interface of the earth's crust an…
Competing field pulse induced dynamic transition in Ising models
Arnab Chatterjee, Bikas K. Chakrabarti
The dynamic magnetization-reversal phenomena in the Ising model under a finite-duration external magnetic field competing with the existing order for has been discussed.…
Money in Gas-Like Markets: Gibbs and Pareto Laws
Arnab Chatterjee, Bikas K. Chakrabarti, S. S. Manna
We consider the ideal-gas models of trading markets, where each agent is identified with a gas molecule and each trading as an elastic or money-conserving (two-body) collision. Unl…
Login times in e-mail servers are scale-free
Arnab Chatterjee
The login time distribution in e-mail servers are studied. The distribution seems to be decaying in a scale-free manner with a decay exponent lying between 1.2 and 2.2, varying fro…
Ideal Gas-Like Distributions in Economics: Effects of Saving Propensity
Bikas K. Chakrabarti, Arnab Chatterjee
We consider the ideal-gas models of trading markets, where each agent is identified with a gas molecule and each trading as an elastic or money-conserving (two-body) collision. Unl…
Pareto Law in a Kinetic Model of Market with Random Saving Propensity
Arnab Chatterjee, Bikas K. Chakrabarti, S. S. Manna
We have numerically simulated the ideal-gas models of trading markets, where each agent is identified with a gas molecule and each trading as an elastic or money-conserving two-bod…
Fluctuation Cumulant Behavior for the Field-Pulse Induced Magnetisation-Reversal Transition in Ising Models
Arnab Chatterjee, Bikas K. Chakrabarti
The universality class of the dynamic magnetisation-reversal transition, induced by a competing field pulse, in an Ising model on a square lattice, below its static ordering temper…
