Structure Functions and Intermittency for Coarsening Systems
Pradeep Kumar Yadav, Mahendra K. Verma, Sanjay Puri
In studies of turbulence, there has been extensive use of physical quantities such as {\it energy transfers} and {\it structure functions}. We examine whether these quantities can…

Coarsening Kinetics in Active Model B+: Macroscale and Microscale Phase Separation
Pradeep Kumar Yadav, Shradha Mishra, Sanjay Puri
We perform a comprehensive numerical investigation of the coarsening kinetics of active Brownian particles modeled by the {\it Active Model B+} (AMB+). This model was introduced by…

Spectral Energy Transfers in Domain Growth Problems
Pradeep Kumar Yadav, Mahendra Kumar Verma, Sanjay Puri
In the domain growth process, small structures gradually vanish, leaving behind larger ones. We investigate spectral energy transfers in two standard models for domain growth: (a)…
