Inflation driven by single geometric tachyon with D-brane orbiting around NS5-branes
Pyung Seong Kwon, Gyeong Yun Jun, Kamal L. Panigrahi +1
We investigate models in which inflation is driven by a single geometrical tachyon. We assume that the D-brane as a probe brane in the background of NS5-branes has non-zero angular…
D-brane orbiting NS5-branes
Gyeong Yun Jun, Pyung Seong Kwon
We study real time dynamics of a Dp-brane orbiting a stack of NS5-branes. It is generally known that a BPS D-brane moving in the vicinity of NS5-branes becomes unstable due to the…
Gauge equivalent universes in 5d Kaluza-Klein theory
Gyeong Yun Jun, Pyung Seong Kwon
We examine in the framework of 5d Kaluza-Klein theory the gauge equivalence of -dependent cosmological solutions each of which describes in the 4d sector an arbitrarily evolvi…
Time Evolution as a Gauge Transformation: x^5-dependent Cosmological Solution in 5d Kaluza-Klein Theory
Gyeong Yun Jun, Pyung Seong Kwon
We discuss a new feature of the 5d Kaluza-Klein cosmology. For that purpose, we obtain the simplest x^5-dependent solution which, in the reduced description, is associated with a r…
