Neutrino Dispersion Relations from a Dark Energy Model
Emilio Ciuffoli, Jarah Evslin, Jie Liu +1
We consider a model in which the neutrino is kinetically coupled to a scalar field and study its implications for environmentally dependent neutrino velocities. Following the usual…
Searching for dark matter isocurvature initial conditions with N-body Simulations
Jie Liu
Small fraction of isocurvature perturbations may exist and correlate with adiabatic perturbations in the primordial perturbations. Naively switching off isocurvature perturbations…
A Multiple Step-like Spectrum of Primordial Perturbation
Jie Liu, Yun-Song Piao
We show that if the inflaton effective potential has multiple discontinuous points in its first derivative, the spectrum of primordial perturbation will be multiple step-like. We g…
CosRayMC: a global fitting method in studying the properties of the new sources of cosmic e excesses
Jie Liu, Qiang Yuan, Xiao-Jun Bi +2
Recently PAMELA collaboration published the cosmic nuclei and electron spectra with high precision, together with the cosmic antiproton data updated, and the Fermi-LAT collaboratio…
