Magnetically decoupled dead zones, originally defined in terms of Ohmic resistivity, have been identified as a central feature of protoplanetary disks. The recognition of the importance of additional non-ideal effects such as ambipolar diffusion or Hall effect has led to serious questioning of the paradigm of magneto-rotational turbulence and has renewed interest in the role played by disk winds and purely hydrodynamic instabilities. Moreover, on small scales, non-ideal dissipation effects can significantly affect the local thermal structure of the magnetically coupled regions of accretion disks, driving thermal processing of solids and powering the hot disk coronae. Central topics for the workshop will include:

  • Establishing a firm basis for non-ideal effects (dusty disk chemistry)
  • Studying small-scale effects of dissipation (current sheets)
  • Exploring the role of winds in mass and momentum transport
  • Extending local numerical work on ambipolar/Hall diffusion to the global domain
  • Characterizing implications for accretion disk and planet formation theory
