A Lapse in the Cosmological Constant Problem with Bulk Dynamics
Justin Khoury, Benjamin Muntz, Antonio Padilla
We have previously proposed a new approach to the cosmological constant problem based on anisotropic scaling in a compact extra dimension. In the ultra-local limit, the inter…
A Lapse in the Cosmological Constant Problem
Justin Khoury, Benjamin Muntz, Antonio Padilla
We present a new mechanism for addressing the cosmological constant problem based on global constraints arising from a lapse function in a higher-dimensional gravitational theory.…
From Frame Covariance to the Swampland Distance Conjecture
Sotirios Karamitsos, Benjamin Muntz
Field space geometry plays a central role within the Swampland Programme, most notably in the various Distance Conjectures. However, for gravitational EFTs, this geometry is not un…
Do we live on the End of the World?
Benjamin Muntz, Antonio Padilla, Paul M. Saffin
We propose a scenario of a de Sitter universe living on an End-of-the-World brane. Motivated by the Swampland programme and in particular the Cobordism Conjecture, we consider a co…
Starobinsky Inflation in the Swampland
Dieter Lust, Joaquin Masias, Benjamin Muntz +1
We argue that the Starobinsky model of inflation, realised via an term in the Lagrangian, can originate from quantum effects due to a tower of light species. By means of two…
