Fractional S-branes on a Spacetime Orbifold
Shinsuke Kawai, Esko Keski-Vakkuri, Robert G. Leigh +1
Unstable D-branes are central objects in string theory, and exist also in time-dependent backgrounds. In this paper we take first steps to studying brane decay in spacetime orbifol…
The Rolling Tachyon Boundary Conformal Field Theory on an Orbifold
Shinsuke Kawai, Esko Keski-Vakkuri, Robert G. Leigh +1
We consider the non-trivial boundary conformal field theory with exactly marginal boundary deformation. In recent years this deformation has been studied in the context of rolling…
Brane Decay from the Origin of Time
Shinsuke Kawai, Esko Keski-Vakkuri, Robert G. Leigh +1
We present a novel scenario where matter in a spacetime originates from a decaying brane at the origin of time. The decay could be considered as a ``Big Bang''-like event at X^0=0.…
The Taming of Closed Time-like Curves
Rahul Biswas, Esko Keski-Vakkuri, Robert G. Leigh +2
We consider a orbifold, where acts by time and space reversal, also known as the embedding space of the elliptic de Sitter space. The background has two potenti…
