BIons in topological string theory

TL;DR

This paper explores the formation of D-brane configurations from stacked fundamental strings within topological string theory, proposing analogous transitions and analyzing them via Fourier transforms of D-brane amplitudes.

Contribution

It introduces a novel analogy of BIon and giant graviton transitions in topological string theory, expanding understanding of D-brane dynamics in this context.

Findings

Demonstrates transitions analogous to BIons and giant gravitons in topological string theory

Shows these transitions can be described by Fourier transforms of D-brane amplitudes

Provides a new perspective on D-brane configurations in topological strings

Abstract

When many fundamental strings are stacked together, they puff up into D-branes. BIons and giant gravitons are the examples of such D-brane configurations that arise from coincident strings. We propose and demonstrate analogous transitions in topological string theory. Such transitions can also be understood in terms of the Fourier transform of D-brane amplitudes.
