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…
