A nearly-massless, slowly-rolling scalar field $\phi$ may provide most of the energy density of the current universe. One potential difficulty with this idea is that couplings to ordinary matter, even if suppressed by the Planck scale, should lead to observable long-range forces and time dependence of the constants of nature. I explore the possibility that an approximate global symmetry serves to suppress such couplings even further. Such a symmetry would allow a coupling of $\phi$ to the…

Perturbations in a scalar field model with virtues of $\Lambda$CDM
In the era of precision cosmology, the cosmological constant $\Lambda$ gives quite an accurate description of the evolution of the Universe, but it is still plagued with the fine-tuning problem and…
Constraining cosmologies with fundamental constants – I. Quintessence and K-essence
Many cosmological models invoke rolling scalar fields to account for the observed acceleration of the expansion of the universe. These theories generally include a potential V (φ) which is a function…
Dark energy, scalar–curvature couplings and a critical acceleration scale
We study the effects of coupling a cosmologically rolling scalar field to higher-order curvature terms. We show that when the strong coupling scale of the theory is on the 10−3–10−1 eV range, the…
Evading equivalence principle violations, cosmological, and other experimental constraints in scalar field theories with a strong coupling to matter
We show that, as a result of nonlinear self-interactions, it is feasible, at least in light of the bounds coming from terrestrial tests of gravity, measurements of the Casimir force and those…
STRINGENT CONSTRAINT ON THE SCALAR–NEUTRINO COUPLING CONSTANT FROM QUINTESSENTIAL COSMOLOGY
An extremely light (mϕ≪10-33eV), slowly-varying scalar field ϕ (quintessence) with a potential energy density as large as 60% of the critical density has been proposed as the origin of the…
Constraints on field flows of quintessence dark energy
The quest for understanding the late-time acceleration is haunted by an immense freedom in the analysis of dynamical models for dark energy in extended parameter spaces. Often-times having no prior…
Dark energy, the swampland, and the equivalence principle
It has recently been argued that string theory does not admit de Sitter vacua. This would imply that the current accelerated expansion of the universe is not driven by a cosmological constant (or…
Constraining Interactions in Cosmology's Dark Sector
We consider the cosmological constraints on theories in which there exists a nontrivial coupling between the dark matter sector and the sector responsible for the acceleration of the universe, in…
Coupled Quintessence and the Halo Mass Function
A sufficiently light scalar field slowly evolving in a potential can account for the dark energy that presently dominates the Universe. This quintessence field is expected to couple directly to…
Natural quintessence in string theory
We introduce a natural model of quintessence in string theory where the light rolling scalar is radiatively stable and couples to Standard Model matter with weaker-than-Planckian strength. The model…
