3-form dark energy and cosmic birefringence
Kohei Kamada, Tucker Manton
3-forms are interesting fields to study in the cosmological context for numerous reasons, such as being candidates for explaining inflation and dark energy. The background evolutio…
Phantom crossing from the Standard Model and General Relativity
Jinglong Liu, Tucker Manton, Yifu Cai +1
Suggestions of a late-time phantom crossing from DESI baryon acoustic oscillation measurements, combined with cosmic microwave background and Type-Ia supernova observations, have r…
Black Hole Interiors as a Laboratory for Time-Dependent Classical Double Copy
Damien A. Easson, Tucker Manton
The classical double copy relates gravity and gauge theory, but its most explicit realizations remain concentrated in stationary or highly symmetric settings. We show that trapped…
Beyond general relativity: gravitational waves in non-minimally coupled theories
Stephon Alexander, Tatsuya Daniel, Tucker Manton
Non-minimal couplings between matter and curvature tensors arise in many different contexts. Such couplings modify solutions of general relativity (GR) and therefore can be probed…
Detecting the -axiverse through parametric resonance
Stephon Alexander, Geoff Beck, Santiago Loane +1
Axions are a leading dark matter candidate. In this work, we study the detectability of a multi-axion-like model, dubbed the -axiverse, that is distinguishable from the string a…
Background ambiguity and the Gödel double copy
Brian Kent, Tucker Manton, Sanjit Shashi
In this work, we investigate the assumptions regarding spacetime backgrounds underlying the classical double copy. We argue (contrary to the norm) that single-copy fields naturally…
The Field Theory Axiverse
Stephon Alexander, Tucker Manton, Evan McDonough
Axion and axion-like particles (ALPs) are a prominent candidate for physics beyond the Standard Model, and can play an important role in cosmology, serving as dark matter or dark e…
The Kalb-Ramond field and Gravitational Parity Violation
Tucker Manton, Stephon Alexander
Gravitational wave physics can probe theories that extend beyond General Relativity. Motivated by the attention on the Kalb-Ramond field as a dark matter candidate, in this work, w…
Isometries and the double copy
Damien A. Easson, Gabriel Herczeg, Tucker Manton +1
In the standard derivation of the Kerr-Schild double copy, the geodicity of the Kerr-Schild vector and the stationarity of the spacetime are presented as assumptions that are neces…
The -axion and -axiverse of dark QCD
Stephon Alexander, Humberto Gilmer, Tucker Manton +1
Axions and axion-like particles (ALPs) are a prominent dark matter candidate, drawing motivation in part from the axiverse of string theory. Axion-like particles can also arise as…
Pure gauge theory for the gravitational spin connection
Stephon Alexander, Tucker Manton
The gravitational spin connection appears in gravity as a non-Abelian gauge field for the Lorentz group , which is non-compact. The action for General Relativity is linear…
Einstein-Maxwell theory and the Weyl double copy
Damien A. Easson, Tucker Manton, Andrew Svesko
The Weyl double copy relates vacuum solutions in general relativity to Abelian gauge fields in Minkowski spacetime. In a previous work, we showed how the Weyl double copy can be ex…
Sources in the Weyl double copy
Damien A. Easson, Tucker Manton, Andrew Svesko
The Weyl double copy relates exact solutions in general relativity to exact solutions in gauge theory, formulated in the spinorial language. To date, the Weyl double copy is unders…
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…
