Horizon Edge Partition Functions in Λ>0 Quantum Gravity
We obtain the spectra of codimension-2 horizon "edge" degrees of freedom for gravity and higher-spin gauge fields in de Sitter space and in the static Nariai spacetime, advancing previous…

Extending the Euler-Heisenberg action to include effects of local Lorentz-symmetry violating backgrounds
This work sets out to compute the corrections to the Euler-Heisenberg effective action that arise from spacetime-dependent background anisotropies that violate Lorentz symmetry. To accomplish our…

Temporal Entanglement in Quantum Field Theory
In this paper I propose a branch point twist field approach to computing the temporal entropy, that is, an entanglement measure across different time regions, as opposed to the usual spacial…

Gaugings of Groupoids, Strings in Shadows, and Emergent Poisson σ-Models
The gauge principle is proposed for rigid Lie-groupoidal symmetries G=>M of the Polyakov-Alvarez-Gawędzki 2d non-linear σ-model with metric target (M,gM) and the WZ term given by a CS…

Thermodynamics and Geometrical Optics of Reissner Nordstrom de Sitter Black Holes in Noncommutative Geometry
We investigate the thermodynamic, optical, and dynamical properties of Reissner-Nordstrom-de Sitter black holes in a noncommutative spacetime with a minimal length scale Theta. Within a two-horizon…

Giant graviton integrated correlators at finite coupling and all orders in 1/N
We study the giant graviton integrated correlator in SU(N) N=4 super Yang-Mills at finite complexified coupling τ. Despite the formidable complexity arising from the heavy nature of…

Some rigidity results for supergravity backgrounds in 11 dimensions
This paper is a contribution to the supersymmetry gap problem for supergravity backgrounds (M,g,F) in 11 dimensions. We study restrictions on the curvature of (M,g,F) and, using the bijective…

Phase Diagram and Finite Temperature Properties of Negative Coupling Scalar Field Theory
In this work, I consider scalar field theory with negative quartic self-interaction, corresponding to an upside-down classical potential. Despite not possessing a classically stable ground state,…

Advances in the Worldline Approach to Quantum Field Theory: Strong Fields, Amplitudes and Gravity
This thesis is devoted to the first-quantized approach to quantum field theory, commonly known as the 'Worldline Formalism'. It collects most of the works completed by the author during the…

Exactly solvable conformal field theories
We review 2d CFT in the bootstrap approach, and sketch the known exactly solvable CFTs with no extended chiral symmetry: Liouville theory, (generalized) minimal models, limits thereof, and loop CFTs,…

Modular Properties of Symplectic Fermion Generalised Gibbs Ensemble
The symplectic fermion is a much-studied non-unitary conformal field theory with c=-2 and is known to contain an infinite family of mutually commuting conserved charges. We derive expressions for…

Towards a Refinement of Krylov Complexity: Scrambling, Classical Operator Growth and Replicas
We propose and test logarithmic Krylov (logK) complexity, an operator growth measure akin to Krylov complexity defined through a replica approach, as a viable probe of early-time operator scrambling…

Comments on the Emergence of 4D Topological Amplitudes in M-Theory
The M-theoretic Emergence Proposal claims that all of the terms in the low-energy action arise from quantum effects. After reviewing the current status of this proposal, we focus on four-dimensional…
