, coauthor of matrix theory. Berenstein's research mainly concerns string theory

String theory

String theory is an active research framework in particle physics that attempts to reconcile quantum mechanics and general relativity. It is a contender for a theory of everything , a manner of describing the known fundamental forces and matter in a mathematically complete system...

. He has made notable contributions to the theory of AdS/CFT conjecture—for example, in 2002 regarding the duality between strings on pp-wave spacetime

Pp-wave spacetime

In general relativity, the pp-wave spacetimes, or pp-waves for short, are an important family of exact solutions of Einstein's field equation. These solutions model radiation moving at the speed of light...
