Tachyon potentials from a supersymmetric FRW model
G. García-Jiménez, C. Ramírez, V. Vázquez-Báez
Considering that the effective theory of closed string tachyons can have worldsheet supersymmetry, as shown by Vafa, we study a worldline supersymmetric action in a FRW background,…
Crossing the phantom divide in an interacting generalized Chaplygin gas
H. Garcia-Compean, G. Garcia-Jimenez, O. Obregon +1
Unified generalized Chaplygin gas models assuming an interaction between dark energy and dark matter fluids have been previously proposed. Following these ideas, we consider a part…
Towards SDp-brane Quantization
H. Garcia-Compean, G. Garcia-Jimenez, O. Obregon +1
The quantum mechanical analysis of the canonical hamiltonian description of the effective action of a SDp-brane in bosonic ten dimensional Type II supergravity in a homogeneous bac…
