Smooth Polar B-Splines with High-Order Regularity at the Origin
Peiyou Jiang, Roman Hatzky, Zhixin Lu +5
We introduce a smooth B-spline discretization in polar coordinates on the unit disc that corrects the loss of regularity present at the origin caused by the coordinate singularity…

Generalized mixed variable-pullback scheme with non-ideal Ohm's law for electromagnetic gyrokinetic simulations
Zhixin Lu, Guo Meng, Roman Hatzky +3
In this work, the non-ideal Ohm's law is integrated in the mixed variable-pullback scheme for the gyrokinetic particle simulations. This scheme captures the evolution of the symple…
