Quantum Liouville Cosmology

Dionysios Anninos, Thomas Hertog, Joel Karlsson

We provide a detailed analysis of the disk path integral of timelike Liouville theory, conceived as a tractable and precise toy-model quantum cosmology in two dimensions. Disk path…

A Holographic Constraint on Scale Separation

Nikolay Bobev, Hynek Paul, Filippo Revello

We propose a new consistency condition for the compatibility of a gravitational effective field theory in AdS with a dual holographic description in terms of a family of large-…

BPS phases and fortuity in higher spin holography

Seok Kim, Jehyun Lee, Siyul Lee +1

We study the BPS states of vector Chern-Simons theory on a sphere at weak coupling , dual to an AdS higher spin gravity. Higher spi…

Probing Quarkonium Diffusion in a Magnetized Quark-Gluon Plasma

Siddhi Swarupa Jena, Arpan Bhattacharjee, David Dudal +1

Motivated by the potential experimental relevance of magnetically affected heavy-quark diffusion, we consider here a five-dimensional nonlinear Einstein-Born-Infeld-dilaton model t…

Bulk/boundary Modular Quintessence and DESI

Luis A. Anchordoqui, Ignatios Antoniadis, Niccolò Cribiori +4

The latest DESI DR2 results, when combined with other independent cosmological data on the Cosmic Microwave Background and supernovas, suggest a preference for dynamical dark energ…

EFT & Species Scale: Friends or foes?

Bruno Valeixo Bento, João F. Melo

Recently the notion that quantum gravity effects could manifest at scales much lower than the Planck scale has seen an intense Swamplandish revival. Dozens of works have explored h…
