Low-Pass Filtering of Active Turbulent Flows to Liquid Substrates
Gianmarco Spera, Julia M. Yeomans, Sumesh P. Thampi
To study the impact of active systems on their surroundings, we introduce a model that couples an active nematic fluid to an isotropic substrate fluid via friction. We numerically…
From Equilibrium Multistability to Spatiotemporal Chaos in Channel Flows of Nematic Fluids
Rahil N. Valani, Sumesh Thampi, Julia M. Yeomans
We investigate channel-confined, nematic liquid crystals using the Beris-Edwards model of nematohydrodynamics. Using strong homeotropic anchoring at the walls, we find multistabili…
Why Extensile and Contractile Tissues Could be Hard to Tell Apart
Jan Rozman, Sumesh P. Thampi, Julia M. Yeomans
Active nematic models explain the topological defects and flow patterns observed in epithelial tissues, but the nature of active stress-whether it is extensile or contractile, a ke…
Lattice Boltzmann Method for Electromagnetic Wave Scattering
Mohd. Meraj Khan, Sumesh P. Thampi, Anubhab Roy
In this work, the lattice Boltzmann method (LBM) is assessed as a time-domain numerical approach for electromagnetic wave scattering. Owing to its explicit formulation and suitabil…
Radiation Forces and Torques on Janus Cylinders
Mohd. Meraj Khan, Sumesh P. Thampi, Anubhab Roy
We investigate radiation-induced drag, lift, and torque on circular Janus cylinders under transverse-magnetic plane-wave illumination, considering metallo-dielectric and purely die…
Channel flows of deformable nematics
Ioannis Hadjifrangiskou, Sumesh P. Thampi, Julia M. Yeomans
We describe channel flows in a continuum model of deformable nematic particles. In a simple shear flow, deformability leads to a nonlinear coupling of strain rate and vorticity, an…
