Understanding and Controlling Turbulent Transport through Cross Phase Control
 

Trying to make Fusion work as a useful energy source on earth requires the control of the turbulent transport of the heat, particles waste and other quantities.  Transport of "stuff" by a turbulent velocity "field" is largely governed by three characteristics; the amplitude (and spectrum) of the turbulence in the velocity, the amplitude of the fluctuations in the "stuff" and the phase between the two.  The impact of the cross phase on the transport will be discussed in the context of enhanced confinement in magnetically confined fusion relevant plasmas such as the I-mode. There will be an emphasis on recent modeling evidence for this and possible control schemes for confined plasmas using external heating which could make this a very useful tool for developing controlled fusion energy.  The importance of the cross phase in turbulent transport in other turbulent systems will also be discussed.
