On the potentials yielding cosmological scaling solutions
In the present work we perform a phase-plane analysis of the complete dynamical system corresponding to a flat FRW cosmological models with a perfect fluid and a self-interacting scalar field and show that every positive and monotonous potential which is asymptotically exponential yields a scaling solution as a global attractor.
متن کاملExponential potentials and cosmological scaling solutions
We present a phase-plane analysis of cosmologies containing a barotropic fluid with equation of state pγ = (γ − 1)ργ, plus a scalar field φ with an exponential potential V ∝ exp(−λκφ) where κ = 8πG. In addition to the well-known inflationary solutions for λ < 2, there exist scaling solutions when λ > 3γ in which the scalar field energy density tracks that of the barotropic fluid (which for exam...
متن کاملMeasurement and significance of cancellation potentials on the human subject.
A versatile four-electrode single-channel system is described which is useful for precise research measurements of mirror patterns on the intact human subject, and the theoretic significance of results obtained on normal subjects for the QRS complex is presented in detail. It is concluded that the QRS complex at all points on the body of normal human subjects, including the pre-cordium, can be ...
متن کاملPerturbative QCD Potential, Renormalon Cancellation and Phenomenological Potentials
We examine the total energy Etot(r) = 2mpole + VQCD(r) of the bb̄ system within perturbative QCD up to O(αS). We extend a previous analysis by incorporating effects of the non-zero charm-quark mass in loops. We find that, once the renormalon cancellation is performed, Etot(r) agrees well with typical phenomenological potentials for heavy quarkonia at distances 0.5 GeV ∼ r ∼ 3 GeV. We also examin...
