Uni-vector deformations, D0-bound states and DLCQ

TL;DR

This paper explores uni-vector deformations in Type IIA string theory, showing how they generate D0-brane bound states and relate to DLCQ of M-theory, with explicit constructions of F1-D0 and D2-D0 backgrounds.

Contribution

It introduces a method to generate D0-brane bound states via uni-vector deformations and connects these to DLCQ of M-theory, providing explicit background constructions.

Findings

D0-brane backgrounds map onto themselves under uni-vector deformation.

Explicit F1-D0 and D2-D0 bound state backgrounds are generated.

Deformation of non-extremal strings yields thermal F1-D0 states.

Abstract

We investigate uni-vector deformation in the Type IIA setup and show that the D0-brane background is mapped into itself (sedimentation), and other extremal backgrounds get bound with a dissolved D0-brane charge. Explicitly we generate F1-D0 and D2-D0 bound states background from uni-vector deformations. For the former we show that deformation of the non-extremal string gives the correct thermal F1-D0 bound state. We discuss relations between critical uni-vector deformations and DLCQ of M-theory.
