个人简介
Barton Zwiebach is presently Professor of Physics at the MIT Department of Physics. Zwiebach was born in Lima, Peru. He has held postdoctoral positions at the University of California, Berkeley, and at MIT, where he became an Assistant Professor of Physics in 1987, and a permanent member of the faculty in 1994.
Professor Zwiebach¹s specialties are String Theory and Theoretical Particle Physics. His central contributions have been in the area of String Field Theory, where he did the early work on the construction of open string field theory and then developed the field theory of closed strings. Zwiebach has also made important contributions to the subject of D-branes with exceptional symmetry and to the subject of tachyon condensation.
In 1999, Ashoke Sen and Zwiebach showed that open string field theory can be used to calculate the tachyon potential and to confirm the existence of a critical point at the expected depth. The developments that followed led to vacuum string field theory, a new version of open string field theory based on the vacuum of the tachyon. In the early 2000's Zwiebach studied the cosmology of closed string tachyons and, together with Okawa and Berkovits, developed heterotic string field theory. Zwiebach then worked on exact analytic solutions in open string field theory. Starting in 2009, Zwiebach and Chris Hull began work on double field theory, an approach that aims to capture the T-duality properties of string theory in effective actions. Together with Olaf Hohm, Hull and Zwiebach constructed an action in terms of the generalized metric that incorporates a number of elements of generalized geometry. Zwiebach continues to work on this area, focusing now on stringy corrections to general relativity.
