Classification of instabilities for the nonideal Brusselator model
Premashis Kumar, Massimiliano Esposito, Timur Aslyamov
We investigate a nonideal, thermodynamically consistent Brusselator reaction-diffusion (RD) system that explicitly incorporates molecular interactions among species in both the dif…
Regulating protocols of globally coupled continuum systems: Effects on dynamics and thermodynamics
Premashis Kumar
Controlling and understanding phenomena in coupled systems remains a significant challenge across diverse fields. This study investigates a simple globally coupled chemical system…
Nonequilibrium thermodynamic signatures of collective dynamical states around chimera in a chemical reaction network
Premashis Kumar, Gautam Gangopadhyay
Different dynamical states ranging from coherent, incoherent to chimera, multichimera, and related transitions are addressed in a globally coupled nonlinear continuum chemical osci…
Glycolytic Wave Patterns in a Simple Reaction-diffusion System with Inhomogeneous Influx: Dynamic Transitions
Premashis Kumar, Gautam Gangopadhyay
An inhomogeneous profile of chemostatted species generates a rich variety of patterns in glycolytic waves depicted in a Selkov reaction-diffusion framework here. A key role played…
Nonequilibrium thermodynamic characterization of chimeras in a continuum chemical oscillator system
Premashis Kumar, Gautam Gangopadhyay
The emergence of the chimera state as counterintuitive spatial coexistence of synchronous and asynchronous regimes is addressed here in a continuum chemical oscillator system by im…
Interplay of energy, dissipation, and error in kinetic proofreading: Control via concentration and binding energy
Premashis Kumar, Kinshuk Banerjee, Gautam Gangopadhyay
Kinetic proofreading mechanisms explain the extraordinary accuracy observed in central biological events in terms of the enhanced specificity of substrate selection networks under…
Nonequilibrium thermodynamics of glycolytic traveling wave: Benjamin-Feir instability
Premashis Kumar, Gautam Gangopadhyay
Evolution of the nonequilibrium thermodynamic entities corresponding to dynamics of the Hopf instabilities and traveling waves at a nonequilibrium steady state of a spatially exten…
Energetic and entropic cost due to overlapping of Turing-Hopf instabilities in presence of Cross Diffusion
Premashis Kumar, Gautam Gangopadhyay
A systematic introduction to nonequilibrium thermodynamics of dynamical instabilities is considered for an open nonlinear system beyond conventional Turing pattern in presence of c…
Limit Cycle Analysis of 3-D Nonlinear systems
Souma Mazumdar, Premashis Kumar, Gautam Gangopadhyay
Considering Limit Cycles as one of the limits of Lienard equation, an analyis analogous to centre manifold analysis has been done for a nonlinear system exhibiting Limit Cycl…
