Social dynamics through kinetic exchange: The BChS model

Soumyajyoti Biswas, Arnab Chatterjee, Parongama Sen +2

This review presents an overview of the current research in kinetic exchange models for opinion formation in a society. The review begins with a brief introduction to previous mode…

Opinion formation models with extreme switches and disorder: critical behaviour and dynamics

Kathakali Biswas, Parongama Sen

In a three state kinetic exchange opinion formation model, the effect of extreme switches was considered in a recent paper. In the present work, we study the same model with disord…

Non-equilibrium dynamics in a three state opinion formation model with stochastic extreme switches

Kathakali Biswas, Parongama Sen

We investigate the non-equilibrium dynamics of a three state kinetic exchange model of opinion formation, where switches between extreme states are possible, depending on the value…

Virtual walks inspired by a mean field kinetic exchange model of opinion dynamics

Surajit Saha, Parongama Sen

We propose two different schemes of realizing a virtual walk corresponding to a kinetic exchange model of opinion dynamics. The walks are either Markovian or non-Markovian in natur…

Non-equilibrium dynamics in Ising like models with biased initial condition

Reshmi Roy, Parongama Sen

We investigate the dynamical fixed points of the zero temperature Glauber dynamics in Ising-like models. The stability analysis of the fixed points in the mean field calculation sh…

The variational method applied to the harmonic oscillator in presence of a delta function potential

Indrajit Ghose, Parongama Sen

The problem of the harmonic oscillator with a centrally located delta function potential can be exactly solved in one dimension where the eigenfunctions are expressed as superposit…
