Chapter 1Introduction

Bethke, Laura Bianca

Pages: 1 –51

[Cosmology is the study of the evolution of our universe, from the Big Bang to the formation of galaxies.]

Chapter 2Chiral Tensor Power Spectrum from Quantum Gravity

Bethke, Laura Bianca

Pages: 53 –90

[Quantum fluctuations that are produced during inflation freeze out after leaving the horizon and can survive until today, as was described in Sect. 1.2.5.]
LitStream

Chapter 3Anisotropic Gravitational Wave Background from Massless Preheating

Bethke, Laura Bianca

Pages: 91 –131

[Reheating is one of the least understood periods in the early universe. While nearly all the elementary particles we observe must have been produced during this period, we still do not know for sure how the process occurred. Although reheating might have an effect on the curvature perturbation...

Chapter 4Concluding Remarks

Bethke, Laura Bianca

Pages: 133 –134

[In this thesis, I have demonstrated that gravitational waves can be used as powerful probes of the early universe. I focussed on two separate topics, tensor perturbations from inflation within a quantum gravity formalism, and gravitational waves from preheating in the presence of a light scalar...
