Title: Swampland conjectures and slow-roll thawing quintessence

Abstract

We examine the Swampland conjectures in the context of generic slow-roll thawing quintessence models. Defining λ≡|$$V'(ϕ_{i})/V(ϕ_{i})$$| and K≡ $$ \sqrt{1-4V''(ϕ_{i})/3V(ϕ_{i})}$$, where ϕ_i is the initial value of ϕ, we find regions of parameter space consistent with both observational data and with the refined de Sitter conjecture, and we show that all such models satisfy the distance conjecture. We quantify the degree of fine-tuning on λ needed to achieve these results.

de Sitter swampland conjecture and the Higgs potential

Journal Article Denef, Frederik ; Hebecker, Arthur ; Wrase, Timm - Physical Review D

According to a conjecture recently put forward in [1], the scalar potential V of any consistent theory of quantum gravity satisfies a bound j∇Vj=V ≥ Oð1Þ. This forbids de Sitter solutions and supports quintessence models of cosmic acceleration. Here, we point out that in the simplest models incorporating the standard model in addition to quintessence, with the two sectors decoupled as suggested by observations, the proposed bound is violated by 50 orders of magnitude. However, a very specific coupling between quintessence and just the Higgs sector may still be allowed and consistent with the conjecture.

Slow-roll thawing quintessence

Journal Article Chiba, Takeshi - Physical Review. D, Particles Fields

We derive slow-roll conditions for thawing quintessence. We solve the equation of motion of {phi} for a Taylor expanded potential (up to the quadratic order) in the limit where the equation of state w is close to -1 to derive the equation of state as a function of the scale factor. We find that the evolution of {phi} and hence w are described by only two parameters. The expression for w(a), which can be applied to general thawing models, coincides precisely with that derived recently by Dutta and Scherrer for hilltop quintessence. The consistency conditions of |w+1|<<1 are derived. Themore »« less

Quantum fine-tuning in stringy quintessence models

Journal Article Hertzberg, Mark P. ; Sandora, McCullen ; Trodden, Mark - Physics Letters B

We investigate the extent to which quintessence models for dark energy are fine-tuned in the context of recent swampland conjectures. In particular, the issue is whether there is a double fine-tuning in which both V and |∇V | are fine-tuned, or whether there is only a single fine-tuning due to the relation |∇V | ~ V /MPl arising naturally. We find that indeed this relation arises naturally in simple string compactifications for some scalars, such as the dilaton and volume modulus, when treated classically. However, we find that quantum effects can spoil this natural relation, unless the scalar is conformallymore »« less

Distance and de Sitter conjectures on the Swampland

Journal Article Ooguri, Hirosi ; Palti, Eran ; Shiu, Gary ; ... - Physics Letters B

Among Swampland conditions, the distance conjecture characterizes the geometry of scalar fields and the de Sitter conjecture constrains allowed potentials on it. We point out a connection between the distance conjecture and a refined version of the de Sitter conjecture in any parametrically controlled regime of string theory by using Bousso’s covariant entropy bound. The refined version turns out to evade all counter-examples at scalar potential maxima that have been raised. We comment on the relation of our result to the Dine–Seiberg problem.

Thawing quintessence with a nearly flat potential

Journal Article Scherrer, Robert J ; Sen, A A ; Center For Theoretical Physics, Jamia Millia Islamia, New Delhi 110025 - Physical Review. D, Particles Fields

The thawing quintessence model with a nearly flat potential provides a natural mechanism to produce an equation of state parameter, w, close to -1 today. We examine the behavior of such models for the case in which the potential satisfies the slow-roll conditions: [(1/V)(dV/d{phi})]{sup 2}<<1 and (1/V)(d{sup 2}V/d{phi}{sup 2})<<1, and we derive the analog of the slow-roll approximation for the case in which both matter and a scalar field contribute to the density. We show that in this limit, all such models converge to a unique relation between 1+w, {omega}{sub {phi}}, and the initial value of (1/V)(dV/d{phi}). We derive thismore »« less
