Asymptotic quasisymmetric high-beta 3D MHD equilibria near axisymmetry
W. Sengupta, N. Nikulsin, R. Gaur +1
Quasisymmetry (QS), a hidden symmetry of the magnetic field strength, is known to support nested flux surfaces and provide superior particle confinement in stellarators. In this wo…

Grad-Shafranov equilibria via data-free physics informed neural networks
Byoungchan Jang, Alan A. Kaptanoglu, Rahul Gaur +3
A large number of magnetohydrodynamic (MHD) equilibrium calculations are often required for uncertainty quantification, optimization, and real-time diagnostic information, making M…

Optimization of Nonlinear Turbulence in Stellarators
Patrick Kim, Stefan Buller, Rory Conlin +8
We present new stellarator equilibria that have been optimized for reduced turbulent transport using nonlinear gyrokinetic simulations within the optimization loop. The optimizatio…
