Research Activities

Two Theories are idntical if both have the some s-matrix elements. Using this, one cand find the effective field theory for different obects in string theory. One class of these objects are D-branes. The world-volume at D-branes in the presence of B-flux became non-commutative. Study of S-matrix elements on the world-volume of these D-branes reveals the fact that the gravity only through open wilson lines can couple to non-commutative D-branes. Some of D-branes in string theory are unstable. They may have application in cosmology. Study of S-matrix elements in this case reveals the fact that the effective action of unstable D-branes is the tachyonic DBI action.
