A theoretical <condensed matter physicist> who, with <Kenneth Geddes Wilson>, calculated <critical exponents> near four dimensions using the <renormalization group>. Expanding in the difference between the dimension and four gave controlled corrections to simple critical behavior. The method connects fluctuations on many length scales to quantitative predictions for a <phase transition>.<Critical Exponents in 3.99 Dimensions by Kenneth Geddes Wilson and Michael Ellis Fisher>[Abstract: small-epsilon expansion and Ising/XY critical exponents]{ref}
