Dark Energy, Extra Dimensions, and the Swampland
Gabriele Montefalcone, Paul J. Steinhardt, Daniel H. Wesley
Perhaps the greatest challenge for fundamental theories based on compactification from extra dimensions is accommodating a period of accelerated cosmological expansion. Previous st…
Vainshtein Mechanism in Binary Pulsars
Claudia de Rham, Andrew J. Tolley, Daniel H. Wesley
We compute the scalar gravitational radiation from a binary pulsar system in the simplest model that exhibits the Vainshtein mechanism. The mechanism is successful in screening the…
Moment transport equations for the primordial curvature perturbation
David J. Mulryne, David Seery, Daniel Wesley
In a recent publication, we proposed that inflationary perturbation theory can be reformulated in terms of a probability transport equation, whose moments determine the correlation…
Multi-field galileons and higher co-dimension branes
Kurt Hinterbichler, Mark Trodden, Daniel Wesley
In the decoupling limit, the DGP model reduces to the theory of a scalar field pi, with interactions including a specific cubic self-interaction - the galileon term. This term, and…
Doppelganger defects
Melinda Andrews, Matt Lewandowski, Mark Trodden +1
We study k-defects - topological defects in theories with more than two derivatives and second-order equations of motion - and describe some striking ways in which these defects bo…
Exploring extra dimensions through observational tests of dark energy and varying Newton's constant
Paul J. Steinhardt, Daniel Wesley
We recently presented a series of dark energy theorems that place constraints on the equation of state of dark energy ($\wdark$), the ime-variation of Newton's constant (),…
