Separate length scale for coarsening and for fractal formation by persistent sites
Dalia Hernandez, Soham Biswas
We present the first example where length scale for the growth of ordered regions and the correlation length for the two point correlations of persistent sites scale differently wi…
From Classical to quantum stochastic process
Gustavo Montes, Soham Biswas, Thomas Gorin
In this paper for the first time, we construct quantum analogs starting from classical stochastic processes, by replacing random which path decisions with superpositions of all pat…
Spontaneous layering and power-law order in the three-dimensional fully-packed hard-plate lattice gas
G. Rakala, D. Mandal, S. Biswas +3
We obtain the phase diagram of fully-packed hard plates on a cubic lattice. Each plate covers an elementary plaquette of the cubic lattice and occupies its four vertices, with each…
Ballistic annihilation in one dimension : A critical review
Soham Biswas, Francois Leyvraz
In this article we review the problem of reaction annihilation on a real lattice in one dimension, where particles move ballistically in one directi…
Zero temperature ordering dynamics in two dimensional BNNNI model
Soham Biswas, Mauricio Martin Saavedra Contreras
We investigate the dynamics of a two dimensional bi-axial next nearest neighbour Ising (BNNNI) model following a quench to zero temperature. The Hamiltonian is given by $H = -J_0\s…
Correlation Matrix Spectra: A Tool for Detecting Non-apparent Correlations?
Soham Biswas, Francois Leyvraz, Paulino Monroy Castillero +1
It has been shown that, if a model displays long-range (power-law) spatial correlations, its equal-time correlation matrix of this model will also have a power law tail in the dist…
Novel Dynamical Phenomena in Magnetic systems
Soham Biswas
Dynamics of Ising models is a much studied phenomenon and has emerged as a rich field of present-day research. An important dynamical feature commonly studied is the quenching phen…
Ballistic annihilation with superimposed diffusion in one dimension
Soham Biswas, Hernán Larralde, Francois Leyvraz
We consider a one-dimensional system with particles having either positive or negative velocity, which annihilate on contact. To the ballistic motion of the particle, a diffusion i…
Universal features of exit probability in opinion dynamics models with domain size dependent dynamics
Parna Roy, Soham Biswas, Parongama Sen
We study the exit probability for several binary opinion dynamics models in one dimension in which the opinion state (represented by ) of an agent is determined by dynamical…
Exit probability in inflow dynamics: nonuniversality induced by range, asymmetry and fluctuation
Parna Roy, Soham Biswas, Parongama Sen
Probing deeper into the existing issues regarding the exit probability (EP) in one dimensional dynamical models, we consider several models where the states are represented by Isin…
Opinion dynamics model with weighted influence: Exit probability and dynamics
Soham Biswas, Suman Sinha, Parongama Sen
We introduce a stochastic model of binary opinion dynamics in which the opinions are determined by the size of the neighbouring domains. The exit probability here shows a step func…
A stochastic opinion dynamics model with domain size dependent dynamic evolution
Suman Sinha, Soham Biswas, Parongama Sen
We introduce a stochastic model of binary opinion dynamics in one dimension. The binary opinions are analogous to up and down Ising spins and in the equivalent spin system,…
Effect of the nature of randomness on quenching dynamics of Ising model on complex networks
Soham Biswas, Parongama Sen
Randomness is known to affect the dynamical behaviour of many systems to a large extent. In this paper we investigate how the nature of randomness affects the dynamics in a zero te…
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…
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…
A new model of binary opinion dynamics: coarsening and effect of disorder
Soham Biswas, Parongama Sen
We propose a model of binary opinion in which the opinion of the individuals change according to the state of their neighbouring domains. If the neighbouring domains have opposite…
Zero temperature dynamics in two dimensional ANNNI model
Soham Biswas, Anjan Kumar Chandra, Parongama Sen
We investigate the dynamics of a two dimensional axial next nearest neighbour Ising (ANNNI) model following a quench to zero temperature. The Hamiltonian is given by $H = -J_0\sum_…
