Stephen L. Adler

Stephen L. Adler, Professor Emeritus in the School of Natural Sciences, joined the Institute Faculty in 1969. In a series of remarkable, difficult calculations, he demonstrated that abstract ideas about the symmetries of fundamental interactions could be made to yield concrete predictions. The successful verification of these predictions was a vital step toward the modern Standard Model of particle physics, which describes elementary particles and their interactions. In some of his more recent work, he has been exploring generalized forms of quantum mechanics, both from a theoretical and a phenomenological standpoint.

The article by Wally Greenberg in the spring 2015 Institute Letter mentions the anomalous axial current triangle diagram and describes its connection with counting quark degrees of freedom. This derives from a calculation I did when a...

I remember fondly the two years I spent at IAS working with Steve Adler on the experimental implications of unified field theories of elementary particle interactions. We also tackled a very hard problem that still is unsolved—how to reconcile...

For slightly over a year, I have largely put aside my longtime interests in the foundations of quantum mechanics and in particle physics, and have been working on dark matter. This interest came about in two different ways. The first was a paper...
