### Tachyon condensation of D2/D4-brane system in noncommutative gauge theory

- Mathematics
- 2002

In this paper we construct the 2+1 effective theory of the light states in D2/D4-brane system in the context of noncommutative Yang-Mills theory. This effective theory is noncommutative and…

### Quantum Corrections to Noncommutative Solitons

- Physics, Mathematics
- 2000

Noncommutative solitons are easier to find in a noncommutative field theory. Similarly, the one-loop quantum corrections to the mass of a noncommutative soliton are easier to compute, in a real…

### 0 Note on Noncommutative Tachyon in Matrix Models

- Physics
- 2000

The solution representing a brane-anti-brane system in matrix models breaks the usual matrix spacetime symmetry. We show that the spacetime symmetry on the branes is not broken, rather appears as a…

### Exact noncommutative solitons

- Physics
- 2000

We find exact solitons in a large class of noncommutative gauge theories using a simple solution generating technique. The solitons in the effective field theory description of open string field…

### ON SOLITONS IN NONCOMMUTATIVE GAUGE THEORIES

- Mathematics
- 2000

Recently there has been a revival of interest in noncommutative gauge theories. They are interesting examples of nonlocal field theories which in the certain limit (of large noncommutativity) become…

We extend the analysis of hep-th/0408069 on a Lorentz invariant interpretation of noncommutative spacetime to field theories on non-anticommutative superspace with half the supersymmetries broken. By…

### Noncommutative Tachyons

- Physics
- 2000

When unstable Dp-branes in type II string theory are placed in a B-ﬁeld, the resulting tachyonic world-volume theory becomes noncommutative. We argue that for large noncommutativity parameter,…

### A Note on Background Independence in Noncommutative Gauge Theories, Matrix Model and Tachyon Condensation

- Mathematics
- 2000

Using the construction of D-branes with nonzero $B$ field in the matrix model we give a physical interpretation of the known background independence in gauge theories on a noncommutative space. The…

### Noncommutative Tachyons And String Field Theory

- Physics, Mathematics
- 2000

It has been shown recently that by turning on a large noncommutativity parameter, the description of tachyon condensation in string theory can be drastically simplified. We reconsider these issues…

### String theory and noncommutative geometry

- Mathematics, Physics
- 1999

We extend earlier ideas about the appearance of noncommutative geometry in string theory with a nonzero B-field. We identify a limit in which the entire string dynamics is described by a minimally…

### Tachyon Condensation and Graviton Production in Matrix Theory

- Physics
- 1999

We study a membrane -- anti-membrane system in Matrix theory. It in fact exhibits the tachyon instability. By suitably representing this configuration, we obtain a (2+1)-dimensional U(2) gauge theory…

### Unstable solitons in noncommutative gauge theory

- Physics, Mathematics
- 2001

We find a class of exact solutions of noncommutative gauge theories corresponding to unstable non-BPS solitons. In the two-dimensional euclidean (or 2+1 dimensional lorentzian) U(1) theory we find…

The study of open string tachyon condensation in string field theory can be drastically simplified by making an appropriate choice of coordinates on the space of string fields. We show that a very…

### Symmetry restoration and tachyon condensation in open string theory

- Physics
- 2001

It has recently been argued that D-branes in bosonic string theory can be described as noncommutative solitons, outside whose core the tachyon is condensed to its ground state. We conjecture that, in…

- Physics
- 2000

It has been conjectured that at a stationary point of the tachyon potential for the D-brane of bosonic string theory, the negative energy density exactly cancels the D-brane tension. We evaluate this…
