Fuzzy Sphere Dynamics and Non-Abelian DBI in Curved Backgrounds
Steven Thomas, John Ward
We consider the non-Abelian action for the dynamics of -branes in the background of -branes, which parameterises a fuzzy sphere using the SU(2) algebra. We find that t…
Inflation from Geometrical Tachyons
Steven Thomas, John Ward
We propose an alternative formulation of tachyon inflation using the geometrical tachyon arising from the time dependent motion of a BPS -brane in the background geometry due t…
Geometrical Tachyon Kinks and NS5 Branes
Steven Thomas, John Ward
We further investigate the 5 ring background using the tachyon map. Mapping the radion fields to the rolling tachyon helps to explain the motion of a probe -brane in this b…
D-brane dynamics near compactified NS5-branes
Steven Thomas, John Ward
We examine the dynamics of a -brane in the background of coincident, parallel 5-branes which have had one of their common transverse directions compactified. We find th…
