Geometrical Tachyon Dynamics in the Background of a Bulk Tachyon Field
Eleftherios Papantonopoulos, Ioanna Pappa, Vassilios Zamarias
We study the dynamics of a D3-brane moving in the background of a bulk tachyon field of a D3-brane solution of Type-0 string theory. We show that the dynamics on the probe D3-brane…
The geometry of wrapped M5-branes in Calabi-Yau 2-folds
Ansar Fayyazuddin, Tasneem Zehra Husain, Ioanna Pappa
We study the geometry of M5-branes wrapping a 2-cycle which is Special Lagrangian with respect to a specific complex structure in a Calabi-Yau two-fold. Using methods recently appl…
Spherically Symmetric Braneworld Solutions with R_{4} term in the Bulk
G. Kofinas, E. Papantonopoulos, I. Pappa
An analysis of a spherically symmetric braneworld configuration is performed when the intrinsic curvature scalar is included in the bulk action; the vanishing of the electric part…
Cosmological Evolution of a Brane Universe in a Type 0 String Background
I. Pappa
We study the cosmological evolution of a D3-brane Universe in a type 0 string background. We follow the brane universe along the radial coordinate of the background and we calculat…
Cosmological Evolution in a Type-0 String Theory
G. A. Diamandis, B. C. Georgalas, N. E. Mavromatos +2
We study the cosmological evolution of a type-0 string theory by employing non-criticality, which may be induced by fluctuations of the D3 brane worlds. We check the consistency of…
Cosmological Evolution of a Brane Universe in a Type 0 String Background
E. Papantonopoulos, I. Pappa
We study the cosmological evolution of a D3-brane Universe in a type 0 string background. We follow the brane-universe along the radial coordinate of the background and we calculat…
