Electromagnetic total-f algorithm for gyrokinetic particle-in-cell simulations with the X-point Gyrokinetic Code XGC

A total-f formulation of the mixed-variable/pull-back electromagnetic simulation algorithm [R. Kleiber et al., Phys. Plasmas 23, 032501 (2016); A. Mishchenko et al., Comput. Phys. Commun. 238, 194 (2019)] for toroidal plasmas is presented for the first time in the XGC edge gyrokinetic particle-in-cell code, starting from the delta-f implementation by M. Cole et al. [Phys. Plasmas 28, 034501 (2021)]. An example simulation is also presented.
