From the collapse of molecular clouds into stars to spectacular galactic mergers, binary systems form on many scales across the universe. Interactions between binaries and their environments can sculpt the stellar populations we observe today, alter...

We analyze a model of qubits which we argue has an emergent quantum gravitational description similar to the fermionic Sachdev-Ye-Kitaev (SYK) model. The model we consider is known as the quantum $q$-spin model because it features $q$-local...

We construct compactifications of type IIB string theory that yield, at leading order in the α ′ α ′ and g s g s expansions, de Sitter vacua of the form envisioned by Kachru, Kallosh, Linde, and Trivedi. We specify explicit Calabi-Yau orientifolds...

Superradiant instabilities may create clouds of ultralight bosons around rotating black holes, forming so-called "gravitational atoms". In this talk, I will review a series of papers that study the effects of a binary companion’s presence. The...

In recent years, there have been various activities trying to better understand the interplay between non-invertible global symmetries and boundary conditions in quantum field theories, with applications ranging from scattering of solitons to...
