Cosmic acceleration from string induced Galileons
Damien A. Easson, Tucker Manton, Andrew Svesko
It has been shown a specific Horndeski theory of gravity arises from a consistent Kaluza-Klein reduction of the gravi-dilaton sector of the low-energy effective heterotic string ac…
A JT supergravity as a double-cut matrix model
Clifford V. Johnson, Felipe Rosso, Andrew Svesko
We study a Jackiw-Teitelboim (JT) supergravity theory, defined as an Euclidean path integral over orientable supermanifolds with constant negative curvature, that was argued by Sta…
The Stringy Origins of Galileons and their Novel Limit
Damien Easson, Tucker Manton, Maulik Parikh +1
We show generalized Galileons -- a particular subclass of Horndeski gravity -- arise from a consistent Kaluza-Klein reduction of the low-energy effective action of heterotic string…
Emergence of Spacetime: From Entanglement to Einstein
Andrew Svesko
Here I develop the connection between thermodynamics, entanglement, and gravity. I begin by showing that the classical null energy condition (NEC) can arise as a consequence of the…
Einstein-Gauss-Bonnet Gravity and Beyond
Damien A. Easson, Tucker Manton, Andrew Svesko
A `novel' pure theory of Einstein-Gauss-Bonnet gravity in four-spacetime dimensions can be constructed by rescaling the Gauss-Bonnet coupling constant, seemingly eluding Lovelock's…
Higher spin partition functions via the quasinormal mode method in de Sitter quantum gravity
Victoria L. Martin, Andrew Svesko
In this note we compute the 1-loop partition function of spin- fields on Euclidean de Sitter space using the quasinormal mode method. Instead of computing the quasino…
