Role of Noise in the Fairen-Velarde model of bacterial respiration

no code implementations12 Apr 2024 Soumyadeep Kundu, Muktish Acharyya

The probability is studied as a function of the width of the noise, and a hyperbolic tangent fitting is proposed.

Existence of two distinct time scales in the Fairen-Velarde model of bacterial respiration

no code implementations9 Oct 2023 Soumyadeep Kundu, Muktish Acharyya

The fixed point solution and the stable limit cycle are found in different parameter ranges as predicted by the linearized differential equations.

Critical Slowing Down along the Separatrix of Lotka-Volterra Model of Competition

no code implementations9 Sep 2022 Sauvik Chatterjee, Muktish Acharyya

It is observed that the time of reaching the stable fixed point in any one of the basins of attraction, depends strongly on the initial distance from the separatrix.

Modelling the Spread of an Epidemic in Presence of Vaccination using Cellular Automata

no code implementations21 Apr 2021 Agniva Datta, Muktish Acharyya

The results of Kermack-McKendrick SIR model are planned to be reproduced by cellular automata (CA) lattice model.

Metastable behavior of the spin-s Ising and Blume-Capel ferromagnets: A Monte Carlo study

no code implementations11 Mar 2021 Moumita Naskar, Muktish Acharyya, Erol Vatansever, Nikolaos G Fytas

We present an extensive Monte Carlo investigation of the metastable lifetime through the reversal of the magnetization of spin-$s$ Ising and Blume-Capel models, where $s=\{1/2, 1, 3/2, 2, 5/2, 3, 7/2\}$.

Metastability in graded and step like variation of field and anisotropy of the Blume-Capel ferromagnet

no code implementations17 Sep 2020 Moumita Naskar, Muktish Acharyya

Metastable lifetime or the reversal time of magnetisation for the system having uniform anisotropy and in the presence of both graded and stepped field has been studied.

Nonequilibrium Multiple Transitions in the Core-shell Ising Nanoparticles Driven by Randomly Varying Magnetic Fields

no code implementations7 Jul 2020 Erol Vatansever, Muktish Acharyya

The nanoparticle system is kept in open boundary conditions and is driven by randomly varying (in time but uniform over the space) magnetic field.

Transient behaviour towards the stable limit cycle in the Selkov model of Glycolysis: A physiological disorder

no code implementations19 May 2020 Tanmay Das, Muktish Acharyya

Deviation from this limit cycle is equivalent to the deviation of normal physiological behaviour.
