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…
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…
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…
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…
