abstract = {<p style="text-align: justify;">The re-splitting $δf$ method (Ye et. al CPC 2020) has been implemented into
the global semi-Lagrangian gyrokinetic code NLT (Lei Ye et al. 2016, JCP) for the
simulations of electromagnetic micro-turbulence in tokamak plasmas. The re-splitting
method can be incorporated with the numerical Lie transform method, which is an
essential numerical scheme for NLT code, to mitigate the cancellation problem appears
in the gyrokinetic $p_{||}$-formulation with gyrokinetic ions and drift-kinetic electrons.
With this method, the ion temperature gradient mode (ITG), the kinetic ballooning
mode (KBM) and trapped electron mode (TEM) are simulated by NLT and the results
are well benchmarked with other gyrokinetic simulation codes.</p>},
