Chemotaxis-induced linear instabilities and pattern formation in a reaction-diffusion model
Mintu Karmakar, Abhik Basu
We study linear instabilities and pattern formation in a spatially extended Selkov model for glycolysis with diffusion and chemotactic interactions between two species. Linear stab…
Re-entrance or monotonic: How chemotaxis controls pattern formation
Mintu Karmakar, Abhik Basu
We investigate pattern formation in generic two-species reaction-diffusion systems with mutual chemotaxis. We show that tuning the chemotaxis strength can give rise to striking non…
Beyond the Markovian limit: Exact solutions for active motion in a power-law viscoelastic bath
Mintu Karmakar, Jure Dobnikar, Ignacio Pagonabarraga
Active particles from bacteria to synthetic microswimmers often navigate viscoelastic media with complex relaxation dynamics. The classical active Brownian model that assumes insta…
Equilibrium and non-equilibrium properties of active matter systems
Mintu Karmakar
Active matter systems encompass both natural and artificially created systems consisting of numerous active particles. These particles actively consume energy to propel themselves…
Field-controlled interfacial transport and pinning in an active spin system
Mintu Karmakar, Matthieu Mangeat, Swarnajit Chatterjee +2
Field control provides a practical route to programmable active matter, yet how weak fields modify non-equilibrium coexistence and interfaces remains unclear. To address this, we s…
Stability of discrete-symmetry flocks: sandwich state, traveling domains and motility-induced pinning
Swarnajit Chatterjee, Mintu Karmakar, Matthieu Mangeat +2
Polar flocks in discrete active systems are often assumed to be robust, yet recent studies reveal their fragility under both imposed and spontaneous fluctuations. Here, we revisit…
The Solar Ultraviolet Imaging Telescope on board Aditya-L1
Durgesh Tripathi, A. N. Ramaprakash, Sreejith Padinhatteeri +75
The Solar Ultraviolet Imaging Telescope (SUIT) is an instrument on the Aditya-L1 mission of the Indian Space Research Organization (ISRO) launched on September 02, 2023. SUIT conti…
Ordering kinetics in the active Ising model
Sayam Bandyopadhyay, Swarnajit Chatterjee, Aditya Kumar Dutta +3
We undertake a numerical study of the ordering kinetics in the two-dimensional () active Ising model (AIM), a discrete flocking model with a conserved density field coupled to…
Consequence of anisotropy on flocking: the discretized Vicsek model
Mintu Karmakar, Swarnajit Chatterjee, Raja Paul +1
We numerically study a discretized Vicsek model (DVM) with particles orienting in possible orientations in two dimensions. The study probes the significance of anisotropic orie…
Agent-Based simulation reveals localized isolation key to saving lives and resources
Mintu Karmakar
In the realm of pandemic dynamics, understanding the intricate interplay between disease transmission, interventions, and immunity is pivotal for effective control strategies. Thro…
Jamming and flocking in the restricted active Potts model
Mintu Karmakar, Swarnajit Chatterjee, Matthieu Mangeat +2
We study the active Potts model with either site occupancy restriction or on-site repulsion to explore jamming and kinetic arrest in a flocking model. The incorporation of such vol…
Self organized criticality of magnetic avalanches in disordered ferrimagnetic material
Suman Mondal, Mintu Karmakar, Prabir Dutta +3
We observe multiple step-like jumps in a Dy-Fe-Ga-based ferrimagnetic alloy in its magnetic hysteresis curve at 2 K. The observed jumps have a stochastic character with respect to…
SEIRD model to study the asymptomatic growth during COVID-19 pandemic in India
Saptarshi Chatterjee, Apurba Sarkar, Mintu Karmakar +2
According to the current perception, symptomatic, presymptomatic, and asymptomatic infectious persons can infect the healthy population susceptible to the SARS-Cov-2. More importan…
