abstract

Dynamical vacuum energy or quintessence, a slowly varying and spatially inhomogeneous component of the energy density with negative pressure, is currently consistent with the observational data. One potential difficulty with the idea of quintessence is that couplings to ordinary matter should be strongly suppressed so as not to lead to observable time variations of the constants of nature. We further explore the possibility of an explicit coupling between the quintessence field and the curvature. Since such a scalar field gives rise to another gravity force of long range ($\simg H^{-1}_0$), the solar system experiments put a constraint on the non-minimal coupling: $|\xi| \siml 10^{-2}$.

  1. Non-minimally coupled scalar field dark sector of the universe: in-depth (Einstein frame) case study

    gr-qc 2025-05 conditional novelty 6.0 of 10

    A complete dynamical-systems stability map for five non-minimally coupled scalar-field dark-energy models, including the negative-potential regime that generically drives the universe to H=0.

  2. Formation of Bound States in Quintessence Alternative Theories

    gr-qc 2025-06 conditional novelty 4.0 of 10

    Bound states of scalar fields exist outside quintessence-dressed AdS black holes for sufficiently large |w| or angular momentum, and quintessence alters the Hawking temperature so that large black holes radiate less.

  3. Modified Gravity Theories on a Nutshell: Inflation, Bounce and Late-time Evolution

    gr-qc 2017-05 accept novelty 2.0 of 10

    Modified gravity theories supply viable mathematical frameworks for inflation, bounces, and dark energy eras that match observational data.
