Detecting Shearless Phase-Space Transport Barriers in Global Gyrokinetic Turbulence Simulations with Test Particle Map Models
Norman M. Cao, Hongxuan Zhu, Gabriel C. Grime +1
In magnetically confined fusion plasmas, the role played by zonal EB flow shear layers in the suppression of turbulent transport is relatively well-understood. However, les…

Construction of symplectic systems from parameter-drift Hamiltonian maps
Gabriel C. Grime, Philip J. Morrison
We reveal the symplectic nature of parameter-drift maps by embedding them into extended phase space. Applying the embedding to the parameter-drift standard nontwist map, our constr…
