Mass freezing in growing neutrino quintessence
Nelson J. Nunes, Lily Schrempp, Christof Wetterich
Growing neutrino quintessence solves the coincidence problem for dark energy by a growing cosmological value of the neutrino mass which emerges from a cosmon-neutrino interaction s…
Do Bound Structures Brake Cosmic Acceleration?
Lily Schrempp, Iain A. Brown
In this paper we investigate the impact of the coupling between a quintessence field and clustered matter on the average equation of state of the scalar field. We take the NFW prof…
Accelerating the Universe with Gravitational Waves
I. A. Brown, L. Schrempp, K. Ananda
Inflation generically produces primordial gravitational waves with a red spectral tilt. In this paper we calculate the backreaction produced by these gravitational waves on the exp…
Relaxing neutrino mass bounds by a running cosmological constant
Florian Bauer, Lily Schrempp
We establish an indirect link between relic neutrinos and the dark energy sector which originates from the vacuum energy contributions of the neutrino quantum fields. Via renormali…
Alpenglow - A Signature for Chameleons in Axion-Like Particle Search Experiments
M. Ahlers, A. Lindner, A. Ringwald +2
We point out that chameleon field theories might reveal themselves as an 'afterglow' effect in axion-like particle search experiments due to chameleon-photon conversion in a magnet…
Neutrino Dark Energy -- Revisiting the Stability Issue
Ole Eggers Bjaelde, Anthony W. Brookfield, Carsten van de Bruck +4
A coupling between a light scalar field and neutrinos has been widely discussed as a mechanism for linking (time varying) neutrino masses and the present energy density and equatio…
Probing the variation of relic neutrino masses with extremely high-energy cosmic neutrinos
Lily Schrempp
We analyze the prospects for testing the cosmic neutrino background and its interpretation as source of Neutrino Dark Energy with the radio telescope LOFAR.
Probing Neutrino Dark Energy with Extremely High-Energy Cosmic Neutrinos
Andreas Ringwald, Lily Schrempp
Recently, a new non-Standard Model neutrino interaction mediated by a light scalar field was proposed, which renders the big-bang relic neutrinos of the cosmic neutrino background…
