D branes in 2 d string theory and Classical Limits
In the matrix model formulation of two dimensional noncritical string theory, a D0 brane is identified with a single eigenvalue excitation. In terms of open string quantities (i.e fermionic eigenvalues) the classical limit of a macroscopically large number of D0 branes has a smooth classical limit : they are described by a filled region of phase space whose size is O(1) and disconnected from th...
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 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 کاملClassical and Quantum D-branes in 2D String Theory
We investigate two classes of D-branes in 2-d string theory, corresponding to extended and localized branes, respectively. We compute the string emission during tachyon condensation and reinterpret the results within the c = 1 matrix model. As in hep-th/0304224, we find that the extended branes describe classical eigenvalue trajectories, while, as found in hep-th/0305159, the localized branes c...
متن کاملD - branes as Tachyon Lumps in String Field Theory
It has been conjectured that the tachyonic lump solution of the open bosonic string field theory describing a D-brane represents a D-brane of one lower dimension. We place the lump on a circle of finite radius and develop a variant of the level expansion scheme that allows systematic account of all higher derivative terms in the string field theory action, and gives a calculational scheme that ...
