Scale-Invariant Open Quantum Systems
Carlos Argüelles, Gabriela Barenboim, Gonzalo Herrera +2
We develop a complete theoretical framework for open quantum systems coupled to scale-invariant environments. We show that such environments are universally described by unparticle…
Universal Description of Decoherence in Scale-Invariant Environments
Carlos Argüelles, Gabriela Barenboim, Gonzalo Herrera +2
When a quantum system couples to a scale-invariant environment, what form must its decoherence take? We prove that the answer is unique: under locality, Lorentz invariance, unitari…
Fifty shades of grayness: parametrizations of spectral distortions and applications in cosmology
Gabriela Barenboim, Julien Froustey, Cyril Pitrou +1
Thermal distribution functions can only be of the Fermi-Dirac or Bose-Einstein types, whereas distorted spectra encompass any possible deviations from these shapes. It is fruitful…
Primordial neutrinos fade to gray: constraints from cosmological observables
Gabriela Barenboim, Julien Froustey, Cyril Pitrou +1
We investigate the effect of potentially large distortions of the relic neutrino spectra on cosmological observables. To that end, we consider a phenomenological model of "gray" sp…
