Activity-induced droplet propulsion and multifractality
Nadia Bihari Padhan, Rahul Pandit
We develop a minimal hydrodynamic model, without an orientational order parameter, for assemblies of contractile swimmers encapsulated in a droplet of a binary-fluid emulsion. Our…
Dynamic multiscaling in stochastically forced Burgers turbulence
Sadhitro De, Dhrubaditya Mitra, Rahul Pandit
We carry out a detailed study of dynamic multiscaling in the turbulent nonequilibrium, but statistically steady, state of the stochastically forced one-dimensional Burgers equation…
An analytical and computational study of the incompressible Toner-Tu Equations
John. D. Gibbon, Kolluru Venkata Kiran, Nadia Bihari Padhan +1
The incompressible Toner-Tu (ITT) partial differential equations (PDEs) are an important example of a set of active-fluid PDEs. While they share certain properties with the Navier-…
Irreversiblity in Bacterial Turbulence: Insights from the Mean-Bacterial-Velocity Model
Kolluru Venkata Kiran, Anupam Gupta, Akhilesh Kumar Verma and +1
We use the mean-bacterial-velocity model to investigate the \textit{irreversibility} of two-dimensional (2D) \textit{bacterial turbulence} and to compare it with its 2D fluid-turbu…
Spiral-wave dynamics in excitable media: Insights from dynamic mode decomposition
Mahesh Kumar Mulimani, Soling Zimik, Jaya Kumar Alageshan +1
Spiral waves are ubiquitous spatiotemporal patterns that occur in various excitable systems. In cardiac tissue, the formation of these spiral waves is associated with life-threaten…
