Non-perturbative time-dependent String Backgrounds and Axion-induced Optical Activity
Jean Alexandre, Nick E. Mavromatos, Dylan Tanner
Conformal invariance for bosonic strings in time-dependent backgrounds of graviton, dilaton and Kalb-Ramond field is obtained by imposing Weyl-beta functions to be homogeneous in t…

Antisymmetric-Tensor and Electromagnetic effects in an alpha'-non-perturbative Four-Dimensional String Cosmology
Jean Alexandre, Nick E. Mavromatos, Dylan Tanner
Starting from an exact (in the Regge slope alpha') functional method for a bosonic stringy sigma-model, we investigate four-dimensional cosmological string solutions in graviton, d…
