Can the cosmological "constant" run? - It may run
Ilya L. Shapiro, Joan Sola
Using standard quantum field theory, we discuss several theoretical aspects of the possible running of the cosmological constant (CC) term in Einstein's equations. The basic motiva…

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…
