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…
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…
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…
