Physics

We work on different aspects of out-of-equilibrium systems such as turbulent flows, magneto-hydrodynamics (MHD), stochastic models etc. Some of the systems that we look at or have looked at (in the past) are mentioned below, 

1. Dynamo effect - Magnetic field generation by Stars and planets: We look at amplification and sustenance of magnetic fields in MHD systems, understanding what kind of flow fields lead to an amplification of the magnetic field and estimate the amplitude of the saturated magnetic field.  

2. Stochastic modelling: We model turbulent/chaotic fields with noise-models to try to capture the effect of noise on instabilities or phase transitions in different out-of-equilibrium systems.

3. Critical transitions: In many situations turbulent flows can undergo transitions from one form of turbulence to another. Such kind of transitions have a critical behaviour, examples include rotating turbulent flows, MHD flows, thin layer turbulence etc. 

4. Wave-mean flow interactions: We study interaction of waves with an underlying mean flow to model atmospheric and oceanic flows.

5. Rotating/Rotating-Stratified flows: Most atmospheric and oceanic flows involve either rotating or rotating-stratified flows. We try to characterise the different regimes observed in such flows using numerical simulations and modelling.
