Accessing the dipole-multipole transition in rapidly rotating spherical shell dynamos
Andrew T. Clarke, Christopher J. Davies, Souvik Naskar +1
Polarity reversals are a key feature of Earth's magnetic field, yet the processes governing them are still poorly understood. Dipole reversals have been found in many numerical dyn…

Force balances in spherical shell rotating convection
S. Naskar, C. J. Davies, J. E. Mound +1
Significant progress has been made in understanding planetary core dynamics using numerical models of rotating convection (RC) in spherical shell geometry. However, the behaviour o…

Path integral approach to driven quantum harmonic oscillator using Markov chain Monte Carlo methods
Sohini Marik, Souvik Naskar, Shibaji Banerjee
We have simulated the ground states of quantum harmonic oscillators driven either by constant forces of different magnitudes or time-dependent driving forces. The expectation value…
