h/2e Flux Trapping without Superconductivity
Recently, it was shown by Komargodski and Popov [arXiv:2601.09847] that ordinary metals threaded with an Aharonov-Bohm solenoid exclusively trap either 0 or h/2e flux. The latter value is familiar in…

Facets of Gravity: A journey exploring spacetime from Planckian to cosmological scales
What does it mean to quantize gravity, and what can a quantum theory of spacetime actually predict? This thesis explores these questions through complementary non-perturbative approaches, from the…

Hilbert space in the flat limit of AdS/CFT. II. Massless particles
Building on Part I of this series, where we described the emergence of massive scattering states, we demonstrate how unitary lowest-weight representations D(Δ,s) of the conformal group…

Proof of the entropic c-theorem
We prove an entropic c-theorem in two dimensions by constructing a c-function from the mutual information between spacelike separated wedges, defined through the relative entropy. The proof…

All Symmetries and Boundaries of the Two-Dimensional Free Scalar from Continuous Flat-Gauging
We propose a remote detectability criterion for two-dimensional conformal field theories, which asserts that any local operator outside of the product of the left- and right-moving Virasoro algebras…

Monopole-Fermion Scattering from Twisted Conformal Boundary States
We derive monopole-fermion scattering correlators from conformal boundary states in twisted sectors. The key ingredient is that symmetry-preserving boundary conditions contain sectors twisted by…

Conformal boundaries and the photon sphere of AdS black holes

On Boundary State Screening via Solitons
We present a coarse classification scheme for the boundary data of massive QFTs based on transitions of boundary states via soliton / kink profiles. Starting from the lattice of boundary states, we…

Giant Gravitons in AdS5×SE5 and the Superconformal Index of Toric Quiver Gauge Theories
We derive giant-graviton contributions to superconformal indices by quantizing probe D3-branes in type IIB backgrounds AdS5× SE5. For SE5=T1,1 and Yp,q, we…

DiscKosky: Efficient Genealogical Constraints from Sector-By-Sector Critical Point Counting

The running of Weyl gauged gravity: asymptotic freedom, its obstruction, and a way out
We compute the one-loop beta functions of quadratic gravity in Weyl conformal geometry, the gauge theory of diffeomorphisms and dilatations with a dynamical Weyl gauge boson. The divergences are…

Guaranteed Slater Conditions for the Numerical Conformal Bootstrap: Fixing Instabilities in SDPB, Navigator Methods, and Skydiving

Quantum Cosmology at the Cusp
In top-down quantum gravity constructions, saxionic directions typically lead to cusps in moduli space, where the scalar potential and the axion decay constant asymptotically behave as $V…

On Geometric Observables in Gravity
Measures of geometry like distance and time are staples of classical gravity. While geometric quantities arise broadly in quantum gravity, their graviton corrections are less explored. In this paper,…
