Induced superstring cosmologies and moduli stabilization
Tristan Catelin-Jullien, Costas Kounnas, Herve Partouche +1
We extend the analysis of the recently obtained stringy cosmological solutions induced by thermal and quantum effects, once space-time supersymmetry is spontaneously broken by geom…
Resolution of Hagedorn singularity in superstrings with gravito-magnetic fluxes
C. Angelantonj, C. Kounnas, H. Partouche +1
We consider closed type II and orientifold backgrounds where supersymmetry is spontaneously broken by asymmetric geometrical fluxes. We show that these can be used to describe ther…
Thermal/quantum effects and induced superstring cosmologies
Tristan Catelin-Jullien, Costas Kounnas, Herve Partouche +1
We consider classical superstring theories on flat four dimensional space-times, and where N=4 or N=2 supersymmetry is spontaneously broken. We obtain the thermal and quantum corre…
A Wave-function for Stringy Universes
Costas Kounnas, Nicolaos Toumbas, Jan Troost
We define a wave-function for string theory cosmological backgrounds. We give a prescription for computing its norm following an earlier analysis within general relativity. Under E…
Noncommutative geometry, Quantum effects and DBI-scaling in the collapse of D0-D2 bound states
C. Papageorgakis, S. Ramgoolam, N. Toumbas
We study fluctuations of time-dependent fuzzy two-sphere solutions of the non-abelian DBI action of D0-branes, describing a bound state of a spherical D2-brane with N D0-branes. Th…
A time-dependent brane in a cosmological background
Nicolaos Toumbas, Jan Troost
We study a moving D-brane in a time-dependent background. There is particle production both because of non-trivial cosmological evolution, and by closed string emission from the br…
