Simulation of the internal kink mode in visco-resistive regimes
Jervis Mendonca, Debasis Chandra, Abhijit Sen +1
We present numerical simulation results of the nonlinear evolution of the (1,1) internal kink mode in the presence of various kinds of equilibrium plasma flows. The present studies…
Numerical simulation of the effect of pellet injection on ELMs
D Chandra, A Sen, A Thyagaraja
We report on numerical simulation studies of the dynamical behavior of edge localized modes (ELMs) under the influence of repetitive injection of pellets. In our nonlinear 2-fluid…
Conservative regularization of compressible dissipationless two-fluid plasmas
Govind S. Krishnaswami, Sonakshi Sachdev, Anantanarayanan Thyagaraja
This paper extends our earlier approach [cf. Phys. Plasmas 17, 032503 (2010), 23, 022308 (2016)] to obtaining a priori bounds on enstrophy in neutral fluids (R-Euler) and ideal mag…
Visco-resistive MHD study of internal kink(m=1) modes
Jervis Mendonca, Debasis Chandra, Abhijit Sen +1
We have investigated the effect of sheared equilibrium flows on the resistive internal kink mode in the framework of a reduced magnetohydrodynamic model in a periodi…
Local conservative regularizations of compressible magnetohydrodynamic and neutral flows
Govind S. Krishnaswami, Sonakshi Sachdev, Anantanarayanan Thyagaraja
Ideal systems like MHD and Euler flow may develop singularities in vorticity (w = curl v). Viscosity and resistivity provide dissipative regularizations of the singularities. In th…
A critique of recent semi-classical spin-half quantum plasma theories
Govind S. Krishnaswami, Rajaram Nityananda, Abhijit Sen +1
Certain recent semi-classical theories of spin-half quantum plasmas are examined with regard to their internal consistency, physical applicability and relevance to fusion, astrophy…
Comment on "Spin-Gradient-Driven Light Amplification in a Quantum Plasma"
Govind S. Krishnaswami, Rajaram Nityananda, Abhijit Sen +1
A comment on the Letter by S. Braun, F. A. Asenjo and S. M. Mahajan, Phys. Rev. Lett., 109, 175003 (2012). We show that recent arguments for light amplification driven by inhomogen…
A critique of recent theories of spin half quantum plasmas
Govind S. Krishnaswami, Rajaram Nityananda, Abhijit Sen +1
In this Letter certain fundamental physics issues relating to recent theories of so-called `spin quantum plasmas' are examined. It is shown that the derivations and some of the res…
