See Schramm–Loewner evolution on Wikipedia. "The acronym SLE is perhaps the most popular way to address this object" (from that article).
Be it "stochastic Loewner equation" or "Schramm–Loewner evolution", it probably is as paradigmatic in probability theory of the 21 century, as the Brownian motion is in probability theory of the 20 century.
Wendelin Werner was awarded Fields medal (2006) "for his contributions to the development of stochastic Loewner evolution, the geometry of two-dimensional Brownian motion, and conformal field theory".
Stanislav Smirnov was awarded Fields medal (2010) "for the proof of conformal invariance of percolation and the planar Ising model in statistical physics" (which is very much related to SLE).
However, we have no article on SLE, nor on percolation.
