Effective Action of Vacuum: Semiclassical Approach
Ilya L. Shapiro
We present brief, to great extent pedagogical review on renormalization in curved space-time and of some recent results on the derivation and better understanding of quantum correc…

Exact Foldy-Wouthuysen transformation for gravitational waves and magnetic field background
Bruno Goncalves, Yuri N. Obukhov, Ilya L. Shapiro
We consider an exact Foldy-Wouthuysen transformation for the Dirac spinor field on the combined background of a gravitational wave and constant uniform magnetic field. By taking th…

Anomaly-induced effective action for gravity and inflation
J. C. Fabris, A. M. Pelinson, I. L. Shapiro
In the very early Universe the matter may be described by the free radiation, that is by the set of massless fields with negligible interactions between them. Then the dominating q…
