The longitudinal fivebrane and tachyon condensation in matrix theory
نویسندگان
چکیده
We study a configuration in matrix theory carying longitudinal fivebrane charge, i.e. a D0-D4 bound state. We calculate the one-loop effective potential between a D0-D4 bound state and a D0–anti-D4 bound state and compare our results to a supergravity calculation. Next, we identify the tachyonic fluctuations in the D0-D4 and D0–anti-D4 system. We analyse classically the action for these tachyons and find solutions to the equations of motion corresponding to tachyon condensation. massar@tena4.vub.ac.be 2 troost@tena4.vub.ac.be; Aspirant F.W.O. 1

NS Fivebrane and Tachyon Condensation
We argue that a semi-infinite D6-brane ending on an NS5-brane can be obtained from the condensation of the tachyon on the unstable D9-brane of type IIA theory. The construction uses a combination of the descriptions of these branes as solitons of the worldvolume theory of the D9-brane. The NS5-brane, in particular, involves a gauge bundle which is operator valued, and hence is better thought of...
متن کاملNote on Noncommutative Tachyon in Matrix Models
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 combination of the matrix spacetime transformation and a gauge transformation. As a result, the tachyon field, itself an off-diagonal entry in longitudinal matrices, transforms nontrivially under rot...
متن کاملD-Brane Dynamics Near NS5-Branes
We use the Dirac-Born-Infeld action to study the real time dynamics of a Dp-brane propagating in the vicinity of NS5-branes. This problem is closely related to tachyon condensation on an unstable D-brane, with the role of the tachyon played by the radial mode on the D-brane. As the D-brane approaches the fivebranes, its equation of state approaches that of a pressureless fluid. The pressure goe...
متن کاملMonopole Condensation and Confining Phase of N = 1 Gauge Theories Via M Theory Fivebrane
The fivebrane of M theory is used in order to study the moduli space of vacua of confining phase N = 1 supersymmetric gauge theories in four dimensions. The supersymmetric vacua correspond to the condensation of massless monopoles and confinement of photons. The monopole and meson vacuum expectation values are computed using the fivebrane configuration. The comparison of the fivebrane computati...
متن کاملLectures on D - branes , tachyon condensation , and string field theory
These lectures provide an introduction to the subject of tachyon condensation in the open bosonic string. The problem of tachyon condensation is first described in the context of the low-energy Yang-Mills description of a system of multiple D-branes, and then using the language of string field theory. An introduction is given to Witten's cubic open bosonic string field theory. The Sen conjectur...
