Elliptic master integrals and the one-loop cosmological wavefunction
Loop corrections to the cosmological wavefunction involve similar integrals to those required for scattering amplitudes. For the one-loop triangle of a conformally coupled scalar, the master…

Collective Bootstrap for Matrix Quantum Mechanics
We develop a collective bootstrap framework for large N matrix quantum mechanics formulated directly in the loop space of single trace coordinate moments. Loop joining and splitting operations…

Unifying energy-entropy bounds in semiclassical gravity
We revisit bounds on energy and entropy in semiclassical gravity, aiming to strengthen and unify established bounds, in particular the quantum focussing conjecture (QFC) and the smeared null energy…

The Effective Field Theory Origin of the Fuzzy Sphere Method
Fuzzy sphere Hamiltonians for (2+1)D conformal field theories are usually written directly on the lowest Landau level. We introduce a framework organizing them as descendants of local ``mother…

Topological interfaces between universes and generalized families of 2d QFTs
Two-dimensional quantum field theories with topological point operators decompose into universes. Just as fusion categories have played an important role in understanding non-invertible symmetries,…

Bootstrapping Wilson lines in Critical Bosonic QED3 Part 1: Large-N endpoint correlators and CFT data
We study the conformal Wilson line with general charge q in critical bosonic QED3 with N complex scalar flavors by combining diagrammatic four-point calculations with endpoint crossing. We…

Conformal Spectrum of (Super) Chiral Ising and XY Models
We determine the spectrum of scaling dimensions of composite operators in the critical Gross-Neveu-Yukawa and Nambu-Jona-Lasinio-Yukawa models through a next-to-leading order semiclassical…

The Non-Relativistic Limit of Five-Dimensional Boson Stars and Scale Invariance Violation
We investigate the non-relativistic limit of spherically symmetric boson stars in (4+1)-dimensional general relativity (GR). In this limit, the resulting Newtonian theory exhibits an exact scale…

Resurgence and Modularity in the First Painlevé Equation
For the first Painlevé equation, we relate three nonlinear Stokes maps associated with a full turn around infinity to modular transformations of the two-parameter tau function through the identity…

The Topological String on the Quintic to Genus 83 and the Rank-Two D4-D2-D0 Indices
We compute quintic Gopakumar-Vafa invariants for genera 2-83 and degrees up to 44 by integrating the holomorphic anomaly equations. Under rank-one modularity for the required Gieseker invariants and…

Tachyon and massless sectors of the bosonic string effective action
Recently, it has been observed that in certain schemes of the bosonic string effective action, the non-derivative tachyon appears only in the tachyon potential, while all other couplings involve…

Circuit complexity of coupled four-mode squeezed states in two-field inflation
We study the circuit complexity of coupled curvature and entropy perturbations in two-field inflation. We start from the quadratic action and derive the full Hamiltonian. The Hamiltonian includes all…

Entropically favored scalar hair on AdS black branes
We construct neutral AdS5 black branes with source-free scalar hair that is entropically favored over the symmetric phase. A quadratic scalar--Gauss--Bonnet coupling destabilizes the thermal state…

Covering Surfaces, Conical-Defect Continuation, and Multi-Entropy at Arbitrary Genus

Creation of the Universe in Lorentzian Classical Gravity
