Richard Arnowitt
From Wikipedia, the free encyclopedia
Richard Arnowitt is an American physicist known for his contributions to theoretical particle physics and to general relativity.
Arnowitt is a Distinguished Professor (Emeritus) at Texas A&M university, where he is a member of the Department of Physics.
His current research interests are centered on supersymmetry and supergravity, from phenomelogy (namely how to find evidence for supersymmetry at current and planned particle accelerators or in the guise of dark matter) to more theoretical questions of string and M theory.[1]
In the context of general relativity, he is best known for his development (with Stanley Deser and Charles Misner) of the ADM formalism, roughly speaking a way of describing spacetime as space evolving in time, which allows a recasting Einstein's theory in terms of a more general formalism used in physics to describe dynamical systems, namely the Hamiltonian formalism. In the framework of that formalism, there is also a straightforward way to define globally quantities like energy or, equivalently, mass (so-called ADM mass/energy) which, in general relativity, is not trivial at all.
