Richard L. Arnowitt (born May 3, 1928 in New York) is an American
physicist known for his contributions to theoreticalparticle physics and togeneral 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 andsupergravity , from phenomenology (namely how to find evidence for supersymmetry at current and plannedparticle accelerator s or in the guise ofdark matter ) to more theoretical questions of string andM theory . [ [http://www.physics.tamu.edu/people/showpeople.php?name=Richard%20Arnowitt&userid=arnowitt Arnowitt's homepage at Texas A&M] ]In the context of
general relativity , he is best known for his development (withStanley Deser andCharles Misner ) of theADM formalism , roughly speaking a way of describingspacetime asspace evolving intime , which allows a recasting of Einstein's theory in terms of a more general formalism used in physics to describe dynamical systems, namely theHamiltonian formalism . In the framework of that formalism, there is also a straightforward way to globally define quantities likeenergy or, equivalently,mass (so-called ADM mass/energy) which, in general relativity, is not trivial at all.Arnowitt is also known for his work (with Ali Chamseddine and Pran Nath) which developed the theory of supergravity grand unification (with gravity mediated breaking). This work allowed for the unification of the three forces of microscopic physics at a very high mass scale (a result subsequently indirectly verified at the CERN LEP accelerator). The simplest version, called mSUGRA, is now commonly used to search for new physics at high energy accelerators. In addition, Arnowitt's work (with Marvin Girardeau) on many body theory of liquid Helium has stimulated many applications in that field.
