Inflation has proven to be an indispensable paradigm for solving the problems of the Standard Big Bang cosmology and, in some of its realizations, it is in total agreement with the latest Cosmic Microwave Background Radiation (CMBR) and Large-Scale Structure (LSS) experiments. In some of these models, where the inflation field traverses large field displacements or inflation lasts long enough, the predictions of these models seem to be sensitive to energies much larger than the inflationary Hubble scale, leading to the possibility that fundamental physics playing an important role in their construction or leaving some traces in the observables. I will briefly review some of the models constructed in string theory and elaborate on their distinctive signatures. I will also comment on the Effective Field Theory (EFT) approach to inflation and its role in the unification of different inflationary scenarios and unraveling new inflationary models with non-Lorentzian dispersion relations for the perturbations in the UV. As inflation can assist us in confining the form of fundamental physics, the signatures from such fundamentally motivated inflationary models can help the cosmologist to come up with new strategies to search for new physics in the data. Inflation and fundamental physics can mutually benefit from each other and flourish together.
The University of Waterloo acknowledges that much of our work takes place on the traditional territory of the Neutral, Anishinaabeg and Haudenosaunee peoples. Our main campus is situated on the Haldimand Tract, the land promised to the Six Nations that includes six miles on each side of the Grand River. Our active work toward reconciliation takes place across our campuses through research, learning, teaching, and community building, and is centralized within our Indigenous Initiatives Office.
