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…
Realizing microrheological response of configurable viscoelastic media with a dynamic optical trap
Sanatan Halder, Manas Khan
The local viscoelastic (VE) environment governs the motion of an embedded microsphere and consequently, pertinent dynamical phenomena. However, studying such phenomena with varying…
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…
Interplay between timescales governs the residual activity of a harmonically bound active Brownian particle
Sanatan Halder, Manas Khan
Active microparticles in confining potentials manifest many complex dynamical phenomena as their activity competes with confinement. The steady-state position distributions of harm…
