Revealing Quintessence

چکیده
Distance measurements to Type 1a supernovae (SNe1a) indicate that the Universe is accelerating and that two-thirds of the critical energy density exists in a component with negative pressure. If that component is an evolving scalar field (‘quintessence’), accurate (5% or so) distance measurements to SNe1a can be used to reconstruct the scalar-field potential. We derive the reconstruction equations and demonstrate the feasibility of this approach by Monte-Carlo simulation.

The Errors of Karen Franklin's Pretextuality
In her recent article, Hebephilia: Quintessence of Diagnostic Pretextuality (published in Behavioral Sciences and the Law, 2010), Karen Franklin expands on her previous argument that psychologists and psychiatrists should not diagnose as abnormal hebephilia, the sexual preference for early pubescent children. She supports her argument with a series of claims about the contents of the empirical ...
متن کاملQuintessence, Flat Potential and String/M Theory Axion
A slow-rolling scalar field (Quintessence) has been proposed as the origin of accelerating universe at present. We discuss some features of quintessence, particularly those related with the flatness of its potential. We distinguish two types of quintessences, a metrical quintessence which couples to the particle physics sector only through the mixing with the spacetime metric and a non-metrical...
متن کاملCorrelated Isocurvature Fluctuation of Quintessence and Curvaton Scenario
We consider cosmic microwave background (CMB) anisotropy in models with quintessence taking into account of isocurvature fluctuation in the quintessence. It is shown that, if the primordial fluctuation of the quintessence has a correlation with the adiabatic density fluctuations, CMB angular power spectrum Cl at low multipoles can be suppressed. Possible scenario of generating correlated mixtur...
متن کاملReconstructing the potentials for the quintessence and tachyon dark energy, from the holographic principle
We propose an holographic quintessence and tachyon models of dark energy. The correspondence between the quintessence and tachyon energy densities with the holographic density, allows the reconstruction of the potentials and the dynamics for the quintessence and tachyon fields, in flat FRW background. The proposed infrared cut-off for the holographic energy density works for two cases of the co...
متن کاملCoupling Quintessence to Inflation in Supergravity
The evolution of the quintessence field during a phase of chaotic inflation is studied. The inflaton φ and the quintesssence field Q are described in a supergravity framework where the coupling between the inflaton and quintessence is induced by non-renormalisable operators suppressed by the Planck mass. We show that the resulting quintessence potential during inflation possesses a time–depende...
