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…
