The Fully Quantized Axion and Dark Energy
Dylan Tanner
This letter reviews the exact evolution equation for the axion effective potential with the axion scale factor f and phenomenological consequences of the flat effective potential s…
Non-perturbative Treatments of the Bosonic String and the Axion with Cosmological Implications
Dylan Tanner
This paper is about the use of a novel, exact functional quantization method as applied to two commonly studied actions in theoretical physics. The functional method in question ha…
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…
