On Noncommutativity in String Theory and D-Branes
String theory in a constant B-field exhibits noncommutative structure of space-time. By considering the B-field dynamical and studying its interaction with Ramond-Ramond (RR) background we observe the breaking of the B-field gauge symmetry in the effective action. This effect takes place due to non-perturbative coupling of the B-field to membrane topological charge. As a result, the B-field is ...
متن کاملD - Branes , Tachyons , and String Field Theory
In these notes we provide a pedagogical introduction to the subject of tachyon condensation in Witten's cubic bosonic open string field theory. We use both the low-energy Yang-Mills description and the language of string field theory to explain the problem of tachyon condensation on unstable D-branes. We give a self-contained introduction to open string field theory using both conformal field t...
متن کاملD-branes in Little String Theory
We analyze in detail the D-branes in the near-horizon limit of NS5-branes on a circle, the holographic dual of little string theory in a double scaling limit. We emphasize their geometry in the background of the NS5-branes and show the relation with D-branes in coset models. The exact one-point function giving the coupling of the closed string states with the D-branes and the spectrum of open s...
متن کاملD-branes and Closed String Field Theory
D-branes have been studied for many years and used to reveal nonperturbative aspects of string theory. As A. Sen argued, D-branes can be realized as soliton solutions in open string field theory. Now some of his conjectures1 have been proved analytically2 in Witten’s open string field theory.3 What we would like to discuss here is how D-branes can be realized in closed string field theory. Hash...
متن کاملD-branes in String theory Melvin backgrounds
We determine the consistent D-brane configurations in type II nonsupersymmetric Melvin Background. The D-branes are analysed from three complementary points of view: the effective Born-Infeld action, the open string partition function and the boundary state approach. We show the agreement of the results obtained by the three different approaches. Among the surprising features is the existence o...
