Activity-induced emergent flatness, instabilities and pattern formation in fluid membranes
Debayan Jana, Astik Haldar, Abhik Basu
We show that microscopically inversion-asymmetric, permeable active fluid membranes are statistically flat and effectively inversion-symmetric at large scales. Their fluctuations a…
Death by mutants: unusual multicritical dynamics in a two-species model for absorbing state transitions
Astik Haldar, Abhik Basu
We explore the phases and active-to-absorbing state phase transitions (AAPT) in a two-species model, where the species A and its mutant B are {\em asymmetrically} or {\em nonrecipr…
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…
Correlated disorder versus correlated noise: Ordering in active systems
Sudip Mukherjee, Abhik Basu
Can quenched disorder generate ordering in driven systems? Using a recently proposed hydrodynamic model, we show that sufficiently long-ranged quenched disorder can induce long-ran…
Quenched activity induces nonuniversal scaling in nonreciprocal XY Models and surfaces
Sudip Mukherjee, Abhik Basu
Active XY models and active surfaces are two paradigmatic nonequilibrium systems with distinct microscopic origins. We show that the hydrodynamic theories for a quenched-disordered…
