Asymmetry-Induced Chiral Dynamics in Coupled Self-Propelled Robots: Spinning and Circular Motion

Priyanka, Nitin Kumar, Harsh Soni

Motivated by the chiral motility of microswimmers, we investigate how geometric asymmetry in a system of two self-propelled active Brownian robots coupled by a spring gives rise to…

An active soft condensed matter approach to the Physics of living systems

Nitin Kumar

This article aims to introduce the broad field of soft active matter physics and its relevance to the life sciences in simple, accessible language. Although this area of research i…

Nematic ordering via vertical stratification in drying clay nanotube suspensions

Arun Dadwal, Meenu Prasher, Nitin Kumar

Evaporative self-assembly offers a simple, cost-effective method for producing functional nanostructured materials. However, achieving tunable and ordered assemblies remains challe…

Spontaneous Emergence of Run-and-Tumble-Like Dynamics in a Robotic Analog of \textit{Chlamydomonas}: Experiment and Theory

Somnath Paramanick, Umashankar Pardhi, Harsh Soni +1

Run-and-tumble (RT) motion is commonly observed in flagellated microswimmers, arising from synchronous and asynchronous flagellar beating. One such example is a biflagellated alga,…

Quantifying nematic order in evaporation-driven self-assembly of Halloysite nanotubes: Nematic islands and critical aspect ratio

Arun Dadwal, Meenu Prasher, Pranesh Sengupta +1

Halloysite nanotubes (HNTs) are naturally occurring clay minerals found in Earth's crust that typically exist in the form of high aspect-ratio nanometers-long rods. Here, we invest…

Catapulting of topological defects through elasticity bands in active nematics

Nitin Kumar, Rui Zhang, Steven A. Redford +2

Active materials are those in which individual, uncoordinated local stresses drive the material out of equilibrium on a global scale. Examples of such assemblies can be seen across…

Phases and excitations of active rod-bead mixtures: simulations and experiments

Harsh Soni, Nitin Kumar, Jyothishraj Nambisan +3

We present a large-scale numerical study, supplemented by experimental observations, of a quasi-two-dimensional active system of polar rods and spherical beads confined between two…
