Localisation with on-shell supersymmetry algebras via the Batalin-Vilkovisky formalism: Localisation as gauge fixing
The Batalin-Vilkovisky formalism provides a powerful technique to deal with gauge and global (super)symmetries that may only hold on shell. We argue that, since global (super)symmetries and gauge…

2D or not 2D: a "holographic dictionary" for Lowest Landau Levels
We consider 2D fermions on a plane with a perpendicular magnetic field, described by Landau levels. It is wellknown that, semiclassically, restriction to the lowest Landau levels (LLL) implies two…

On the phase of the de Sitter density of states
The one-loop gravitational path integral around Euclidean de Sitter space SD has a complex phase that casts doubt on a state counting interpretation. Recently, it was proposed to cancel this phase…

Emergent Area Operators in the Boundary
In some cases in two and three bulk dimensions without bulk local degrees of freedom, I look for area operators in a fixed boundary theory. In each case, I define an exact quantum error-correcting…

8D conformal gravity with Einstein sector, and its relation to the Q-curvature
We first streamline the construction of the unique six-dimensional conformal gravity action found by Lü, Pang and Pope, that admits Einstein metrics as solutions to the field equations. We then prove…

Symmetry-Resolved Entanglement Entropy from Heat Kernels
We develop a systematic framework for computing symmetry-resolved entanglement entropies (SREE) in charged quantum systems based on an improved heat kernel approach. Although the conventional…

Translation invariant defects as an extension of topological symmetries
The modern way to understand symmetries of a quantum field theory is via its topological defects in various dimensions. In this contribution to the proceedings we focus on line defects in 2d QFT and…

Near-extremal membranes in M-theory
We consider near-extremal membranes embedded in M-theory, consistently truncated to gauged N = 2 supergravity in four dimensions on the coset space M1,1,0. These are holographically…

Entanglement asymmetry in gauge theories: chiral anomaly in the finite temperature massless Schwinger model
The entanglement asymmetry has emerged in recent years as a practical quantity to study phases of matter. We present the first study of entanglement asymmetry in gauge theories by considering the…

Symmetries and dualities in non-supersymmetric CHL strings

Wiggling boundary and corner edge modes in JT gravity with defects
We study the gravitational edge modes (GrEMs) and gauge edge modes (GaEMs) in Jackiw-Teitelboim (JT) gravity on a wiggling boundary. The wiggling effect manifests as a series of spacetime topological…

Black holes and dualities in string theory compactifications
This thesis addresses three problems arising in type II string theory compactified on a Calabi-Yau manifold. In the first one we study the hypermultiplet moduli space (HM), by working on its twistor…
