Revisiting Kinematic Fast Dynamo in 3-dimensional magnetohydrodynamic plasmas: Dynamo transition from non-Helical to Helical flows
Shishir Biswas, Rajaraman Ganesh
Dynamos wherein magnetic field is produced from velocity fluctuations are fundamental to our understanding of several astrophysical and/or laboratory phenomena. Though fluid helici…
Ion-driven destabilization of a toroidal electron plasma -- A 3D3VPIC Simulation
Swapnali Khamaru, Rajaraman Ganesh, Meghraj Sengupta
Ion resonance instability of toroidal electron plasmas in a tight aspect ratio axisymmetric toroidal device is reported for ions of different initial density values using…
Scaling of reconnection parameters in magnetic island coalescence: Role of in-plane shear flow
Jagannath Mahapatra, Rajaraman Ganesh, Abhijit Sen
A 2D incompressible viscoresistive-MHD model [Mahapatra et. al., Phys. Plasmas 28, 072103 (2021)] is used to study the scaling of reconnection parameters in magnetic island coalesc…
Coupling of "cold" electron plasma wave via stationary ion inhomogeneity to the plasma bulk
Sanjeev Kumar Pandey, Jagannath Mahapatra, Rajaraman Ganesh
Using high resolution kinetic (VPPM-OMP 1.0) and fluid (BOUT++) solvers, evolution of long-wavelength electron plasma wave (EPW) in the presence of stationary periodic ion backgrou…
Long time fate of two-dimensional incompressible high Reynolds number Navier-Stokes turbulence: A quantitative comparison between theory and simulation
Shishir Biswas, Rajaraman Ganesh
Predicting the long time or late time states of two-dimensional incompressible, high Reynolds number, slowly decaying turbulence has been one of the long-standing problems. Using `…
Quantum dimer model on fullerenes: resonance, scarring and confinement
R. Krishna Prahlaadh, R. Ganesh
The earliest known examples of quantum superposition were found in organic chemistry -- in molecules that `resonate' among multiple arrangements of -bonds. Small molecules such…
Berry phase in the rigid rotor: the emergent physics of odd antiferromagnets
Subhankar Khatua, R. Ganesh
The rigid rotor is a classic problem in quantum mechanics, describing the dynamics of a rigid body with its centre of mass held fixed. The configuration space of this problem is $S…
