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…
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…
The classical double copy of non-singular black holes
Damien A. Easson, Cynthia Keeler, Tucker Manton
We apply the classical double copy procedure to a class of regular, non-singular black hole solutions. We give several examples, paying particular attention to a string-theory-corr…
From Navier-Stokes to Maxwell via Einstein
Cynthia Keeler, Tucker Manton, Nikhil Monga
We revisit the cutoff surface formulation of fluid-gravity duality in the context of the classical double copy. The spacetimes in this fluid-gravity duality are algebraically speci…
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…
Stable Cosmic Time Crystals
Damien A. Easson, Tucker Manton
Cosmological time crystals are created when a scalar field moves periodically through phase space in a spatially flat Friedmann-Robertson-Walker spacetime due to the presence of a…
