CMB anisotropy induced by tachyonic perturbations of dark energy
M. V. Libanov, V. A. Rubakov, O. S. Sazhina +1
We study effects of possible tachyonic perturbations of dark energy on the CMB temperature anisotropy. Motivated by some models of phantom energy, we consider both Lorentz-invarian…

Lorentz-violation and cosmological perturbations: a toy brane-world model
M. V. Libanov, V. A. Rubakov
We study possible effects of Lorentz-violation on the generation of cosmological perturbations at inflation by introducing a simple inflating five-dimensional brane-world setup wit…
