The classification of solids into insulators and metals is based on their electrical responses, with the Fermi surface shape being crucial for the physical properties of metals. A key experimental method for detecting the Fermi surface involves measuring quantum oscillations, which are periodic responses to external magnetic fields. In contrast, insulators, lacking a Fermi surface, are thought not to display any quantum oscillations, highlighting a significant distinction between these two categories of materials.

The thesis explores quantum gravity to uncover the origins and mechanisms of the universe. The author and collaborators enhance the analyticity of two models, causal dynamical triangulations (CDT) and n-DBI gravity, focusing on the shared element of space-time foliation. This rigorous investigation aims to deepen the understanding of fundamental cosmic questions through advanced theoretical frameworks.
