Ion-temperature-gradient turbulence from finite to weak magnetic shear regime
Zihao Wang, Tiannan Wu, Shaojie Wang
The tokamak, a toroidal magnetic device confining a hot plasma, is one of the most advanced approaches to fusion energy. A central obstacle is turbulent transport driven by the ion…
Observation of the electric Breit-Rabi Effect
S. -Z. Wang, S. -B. Wang, Z. -J. Tao +2
The response of an atom to external electric and magnetic fields can reveal fundamental atomic properties. It has long been verified that, in a static magnetic field, those atomic…
Optimizing stellarators with hidden symmetry
Hengqian Liu, Guodong Yu, Caoxiang Zhu +8
Stellarators confine fusion plasmas using three-dimensional magnetic fields composed of nested toroidal magnetic surfaces. In generic stellarators, trapped particles can drift acro…
Unified mesoscale picture of nonlinear generation of zonal flows in toroidal geometry
Zihao Wang, Shaojie Wang
Recent experimental findings on limit-cycle-oscillations indicate that the nonlinear driving of the turbulent poloidal Reynolds stress to zonal flows is not a significant factor in…
Gyrokinetic simulation of the spontaneous toroidal rotation of plasma in a stochastic magnetic field
Jinxiang You, Shaojie Wang
Since the DIII-D resonant magnetic perturbation experiment [Nucl. Fusion , 126010 (2019)] suggests that the neoclassical toroidal viscosity due to the collisional effects…
Numerical dissipation induced by the low-pass filtering in nonlinear gyrokinetic simulations
Zihao Wang, Shaojie Wang
De-aliasing is an essential procedure for eliminating the aliasing error in nonlinear simulations, such as nonlinear gyrokinetic turbulence simulations. An ideal approach to de-ali…
Discretization form of the continuity condition at the polar axis, with application to the gyrokinetic simulation in a magnetic fusion torus
Tiannan Wu, Zihao Wang, Shaojie Wang
A new computational method to solve the hyperbolic (Vlasov) equation and the elliptic (Poisson-like) equation at the polar axis is proposed. It is shown that the value of a scalar…
Evolution of self-organized structure, the internal transport barrier in the ion-temperature-gradient driven gyrokinetic turbulence
S. Wang, Z. Wang, T. Wu
Understanding the self-organization of the most promising internal transport barrier in fusion plasmas needs a long-time nonlinear gyrokinetic global simulation. The Neighboring Eq…
