Toward a quantum field theoretical description of oscillation effects
Maxim Libanov
In this paper, we propose an approach based on the theory of an axiomatic matrix and partially switching on an interaction, which is extremely suitable for describing the pheno…
Perturbations on and off de Sitter brane in anti-de Sitter bulk
M. Libanov, V. Rubakov
Motivated by holographic models of (pseudo)conformal Universe, we carry out complete analysis of linearized metric perturbations in the time-dependent two-brane setup of the Lykken…
Generalized Galileons: instabilities of bouncing and Genesis cosmologies and modified Genesis
M. Libanov, S. Mironov, V. Rubakov
We study spatially flat bouncing cosmologies and models with the early-time Genesis epoch in a popular class of generalized Galileon theories. We ask whether there exist solutions…
Towards conformal cosmology
M. Libanov, V. Rubakov, G. Rubtsov
Approximate de Sitter symmetry of inflating Universe is responsible for the approximate flatness of the power spectrum of scalar perturbations. However, this is not the only option…
Conformal Universe as false vacuum decay
M. Libanov, V. Rubakov
We point out that the (pseudo-)conformal Universe scenario may be realized as decay of conformally invariant, metastable vacuum, which proceeds via spontaneous nucleation and subse…
On holography for (pseudo-)conformal cosmology
M. Libanov, V. Rubakov, S. Sibiryakov
We propose a holographic dual for (pseudo-)conformal cosmological scenario, with a scalar field that forms a moving domain wall in adS_5. The domain wall separates two vacua with u…
