Active Brownian motion in a single-relaxation viscoelastic fluid
Sanatan Halder, Manas Khan
Active Brownian particles (ABPs) in viscoelastic (VE) media exhibit fascinating dynamical phenomena set by self-propulsion, thermal fluctuations, and fluid viscoelasticity. We exte…
Identifying the signatures of residual activity in harmonically bound active Brownian dynamics
Sanatan Halder, Manas Khan
A confined self-propelled particle exhibits a range of intriguing dynamical phenomena dictated by the interplay between the intrinsic activity of the particle and the imposed confi…
Emulating microbial run-and-tumble and tactic motion by stochastically reorienting synthetic active Brownian particles
Sandip Kundu, Dibyendu Mondal, Arup Biswas +2
Replicating efficient and adaptable microbial navigation strategies, such as run and tumble (RnT) and tactic motions to synthetic active agents has been an enduring quest. To this…
Dynamically stable optical trapping of thermophoretically active Janus colloids
Sanatan Halder, Manas Khan
The ability to optically trap and manipulate artificial microswimmers such as active Janus particles (JPs) provides a breakthrough in active matter research and applications. Howev…
