On a quantization of deformed reducible gauge theories
A. A. Averianov, A. O. Barvinsky, I. L. Buchbinder +2
We consider a general reducible gauge theory deformed by mass or/and interaction terms violating gauge invariance. It is shown that in the Abelian case, by using the Stueckelberg-t…
Covariant quantization of totally antisymmetric tensor-spinor field in
A. O. Barvinsky, I. L. Buchbinder, V. A. Krykhtin +1
We develop the quantization of a recently proposed model describing a totally antisymmetric rank- tensor-spinor field (a fermionic -form theory) in -dimensional anti-de Si…
Dynamics of the generalized unimodular gravity theory
A. O. Barvinsky, N. Kolganov, A. Kurov +1
The Hamiltonian formalism of the generalized unimodular gravity theory, which was recently suggested as a model of dark energy, is shown to be a complicated example of constrained…
Heat kernel methods for Lifshitz theories
Andrei O. Barvinsky, Diego Blas, Mario Herrero-Valea +3
We study the one-loop covariant effective action of Lifshitz theories using the heat kernel technique. The characteristic feature of Lifshitz theories is an anisotropic scaling bet…
Origin of inflation in CFT driven cosmology: -gravity and non-minimally coupled inflaton models
A. O. Barvinsky, A. Yu. Kamenshchik, D. V. Nesterov
We present a detailed derivation of the recently suggested new type of hill-top inflation [arXiv:1509.07270] originating from the microcanonical density matrix initial conditions i…
New type of hill-top inflation
A. O. Barvinsky, A. Yu. Kamenshchik, D. V. Nesterov
We suggest a new type of hill-top inflation originating from the initial conditions in the form of the microcanonical density matrix for the cosmological model with a large number…
