Recent work at Hiroshima on drift wave turbulence and associated transport

Recent developments in the theory of drift wave turbulence and associated transport phenomena are reviewed within the framework of the weak turbulence theory. Basic physical effects leading to anomalous cross-field transport of particles and energies are discussed in detail for the case of collisionless electrostatic drift waves in a uniform magnetic field. Effects of electro-magnetic perturbations (finite-β effect), magnetic shear and toroidal geometry are also discussed.
