We provide an overview on diffusion in frictionless two‐dimensional Yukawa liquids as a model for dusty plasmas. Results are obtained for the combined influence of temperature and screening length on the character of diffusion, i.e., on the value of the diffusion exponent at long times (© 2009 WILEY‐VCH Verlag GmbH & Co.
