Absorption Cross Section of Smeared D3-Brane on a Circle
Anastasios Psinas
The evaluation of the absorption cross section of a massless scalar field propagating on a non-extremal black D3-brane smeared on a circle is considered. The solution to the scalar…
Mirage Cosmology on Unstable D3-Brane Universe
Anastasios Psinas
We study the geodesic motion of an unstable brane moving in a higher dimensional bulk spacetime. The tachyon which is coupled to a U(1) gauge field induces a non-trivial cosmologic…
Quantum Cosmology Aspects Of D3 Branes and Tachyon Dynamics
Anastasios Psinas
We investigate aspects of quantum cosmology in relation to string cosmology systems that are described in terms of the Dirac-Born-Infeld action. Using the Silverstein-Tong model, w…
Mirage Cosmology of U(1) Gauge Field on Unstable D3 Brane Universe
Anastasios Psinas
An unstable -brane universe governed by the DBI action of the tachyon field minimally coupled to a U(1) gauge boson is examined. The cosmological evolution of this coupled syst…
