Axion-Dilaton Quantum String Cosmology for Flux Compactification and its Symmetry Breaking
arXiv:0710.1228
Abstract
The Wheeler-De Witt equation of type IIB quantum string cosmology compactified with constant internal H-fluxes on a 6-torus, whose volume modulus is frozen, is solved under the WKB approximation. The spontaneous symmetry breaking of the S-duality group by H-fluxes is also examined.
