- 요약This thesis is based on two key papers [1,2] which came out of my PhD research. In the first half of this thesis, I study aspects of geometry and field theory in a version of dS-JT gravity which was conjectured by Leonard Susskind and myself [3-9]1 to be holographically dual to the high-temperature double-scaled limit of the SYK model. The notion of holographic duality employed here is that of static patch horizon holography (see e.g. [14] and references therein). In this context, I describe an example of holographic bulk emergence and discuss some related constraints on the boundary-to-bulk operator mapping. In the second half of this thesis based on [2], written in collaboration with Leonard Susskind we discuss some general insights and surprises which follow from the static patch perspective on de Sitter space (in any dimension). Specific focus is given to the example of massive vector Bosons as seen by a static patch observer. From this perspective, these vector Bosons appear to be controlled by an effective physical mass which deviates from the "naive" mass appearing in the usual dS-Proca Lagrangian by a term which is proportional to the cosmological constant. We argue that this deviation allows the theory to be well-defined (at least from the static patch perspective) in a naively tachyonic range of parameters, up to what we term the "edge of stability". We identify and explain several interesting features which appear at the edge of stability and explicitly demonstrate the classical stability of the theory in this new parameter range.
