A Variational Framework for Guiding-Center Kinetics, Anisotropic Equilibria, and Quasisymmetry in Stellarators
Lanke Fu, Amitava Bhattacharjee
We present a variational framework in which (i) guiding-center kinetics, (ii) macroscopic force balance with gyrotropic pressure, and (iii) quasisymmetry (QS) appear as facets of a…
A flexible and differentiable coil proxy for stellarator equilibrium optimization
Lanke Fu, Dario Panici, Elizabeth Paul +2
Balancing plasma performance and coil cost is a significant challenge when designing a stellarator power plant. Most current stellarator designs are produced through two-stage opti…
Plasmoid solutions of the Hahm--Kulsrud--Taylor equilibrium model
R. L. Dewar, A. Bhattacharjee, R. M. Kulsrud +1
The Hahm--Kulsrud (HK) [T. S. Hahm and R. M. Kulsrud, Phys. Fluids {\bf 28}, 2412 (1985)] solutions for a magnetically sheared plasma slab driven by a resonant periodic boundary pe…
Large-Scale High-Lundquist Number Reduced MHD Simulations of the Solar Corona Using GPU Accelerated Machines
L. Lin, C. S. Ng, A. Bhattacharjee
We have recently carried out a computational campaign to investigate a model of coronal heating in three-dimensions using reduced magnetohydrodynamics (RMHD). Our code is built on…
Generalizations of a Nonlinear Fluid Model for Void Formation in Dusty Plasmas
C. S. Ng, A. Bhattacharjee, S. Hu +2
New developments in the theory and numerical simulation of a recently proposed one-dimensional nonlinear time-dependent fluid model [K. Avinash, A. Bhattacharjee, and S. Hu, Phys.…
A Constrained Tectonics Model for Coronal Heating
C. S. Ng, A. Bhattacharjee
An analytical and numerical treatment is given of a constrained version of the tectonics model developed by Priest, Heyvaerts, & Title [2002]. We begin with an initial uniform magn…
