We propose a class of simple dark energy models which predict a late-time dark radiation component and a distinctive time-dependent equation of state w(z) for redshift z < 3. The dark energy field can be coupled strongly enough to standard model particles to be detected in colliders, and the model requires only modest additional particle content and little or no fine-tuning other than a new energy scale of order milli-electron volts.

Eliashberg Formalism

The marginal Fermi liquid (MFL) which describes the anomalous normal state of the cuprates is extended to a d-wave superconductive state. A phenomenological collective excitation, P0(ω,T), is taken such that it gives rise to, after renormalization, the MFL behavior in the normal state. With the P0, the renormalized excitation spectrum and pairing function in superconductive state are calculated self-consistently within the Eliashberg formalism. In the superconductive state, the self-energy deviates from the normal state MFL ω/T-scaling and develops a new energy scale of ω0≈2Δ, where Δ is the pairing amplitude.

New Energy

A framework is proposed for field theory with a new energy scale. The proposal is based on the idea, appearing for example in Deformed Special Relativity (DSR), of building phenomenological models for quantum gravity by taking momentum space to be curved rather than flat. In this work, this idea is implemented by introducing a fifth dimension and by imposing an extra constraint on physical field configurations in addition to the mass shell constraint. Advantages of this approach are that Lorentz symmetry is explicitly preserved and that an interacting scalar field model constructed in this way can be shown to be unitary. Implications for electrodynamics are discussed but the interpretation of the extra dimension needs to be clarified before making predictions for experiments.
