We analyze the ideal-gas-like models of markets and review the different cases where a ‘savings’ factor changes the nature and shape of the distribution of wealth. These models can produce similar distribution of wealth as observed across varied economies. We present a more realistic model...

We introduce a simple cellular-network model to explain the capacity of the plants as memory devices. Following earlier observations (Bose (The Nervous Mechanism of Plants, Longmans, London, 1923) and others), we regard the plant as a network in which each of the elements (plant cells) are...

We study phenomenological scaling theories of the polymer dynamics in random media, employing the existing scaling theories of polymer chains and the percolation statistics. We investigate both the Rouse and the Zimm model for Brownian dynamics and estimate the diffusion constant of the...

We have studied the nature of the response function (magnetisation) arising in response to a periodic perturbation (magnetic field) on Ising systems, using the Monte Carlo simulation (for a three dimensional Ising system) and also solving the mean field equation of Ising dynamics. The hysteresis...

We review here briefly some of our recent studies on neural network modelling. We discuss the studies on relaxation and growth of correlation in the Hopfield model, increase in memory loading capacity with an extended Hopfield-like model with delayed dynamics, the prediction capability of time...

It is seen from extensive computer simulation results and some experimental observations that for inhomogenous solids with moving cracks, the surface roughness exponent ζ crosses over from a low value ζ∼0.42 to a higher value ζ∼0.8, as the crack-tip velocity increases above a certain...

In a Monte Carlo study of the two dimensional Ising system (of size 100 × 100) with nearest neighbour ferromagnetic interaction in the presence of a sinusoidally varying external magnetic field, we studied the variation of the hysteretic loop area (A) with frequency (f), amplitude (h0) of...

In this communication we report the existence of a dynamic “spin-reversal” transition in an Ising system perturbed by a pulsed external magnetic field. The transition is achieved by tuning the strength (hp) and/or the duration (Δt) of the pulse which is applied in a direction opposite to...

We study the dynamics of the “Kolkata Paise Restaurant problem”. The problem is the following: In each period, N agents have to choose between N restaurants. Agents have a common ranking of the restaurants. Restaurants can only serve one customer. When more than one customer arrives at the...
