Yan-Gang Miao, Harald J.W. M\"uller-Kirsten, Dae Kil Park
TL;DR
This paper derives a periodic bounce solution in Born-Infeld theory for D3-branes, illustrating tachyon condensation as an unstable string between brane-antibrane pairs, and discusses the BPS limit of infinite period.
Contribution
It provides an explicit bounce solution in Born-Infeld theory and interprets it as a tachyon condensation process in the D3-anti-D3 system.
Findings
Explicit bounce solution derived
Connection to tachyon condensation established
BPS limit discussed as infinite period case
Abstract
The periodic bounce of Born-Infeld theory of -branes is derived, and the BPS limit of infinite period is discussed as an example of tachyon condensation. The explicit bounce solution to the Born--Infeld action is interpreted as an unstable fundamental string stretched between the brane and its antibrane.
