This article aims at discussing the cosmological constant problem at a pedagogical but fully
technical level. We review how the vacuum energy can be regularized in flat and curved …

We investigate the gravitational property of the quantum vacuum by treating its large energy
density predicted by quantum field theory seriously and assuming that it does gravitate to …

In this paper I review various developments in the past year concerning quantum vacuum
energy, the Casimir effect. In particular, there has been continuing controversy surrounding …

We study the Casimir effect in the framework of standard model extension. Employing the
weak field approximation, the vacuum energy density ε ε and the pressure for a massless …

In this paper, we study the Casimir effect in a curved spacetime described by gravitational
actions quadratic in the curvature. In particular, we consider the dynamics of a massless …

We investigate the influence of a time-varying spacetime background on the vacuum
polarization of a massless quantum field confined to a Casimir cavity. The background is …

In this paper we discuss the Casimir effect in a small cavity, freely falling from spatial infinity
in spacetime geometry outside of a Schwarzschild black hole. Our main goal is to search for …

The force exerted by the gravitational field on a Casimir cavity in terms of Archimedes force
of vacuum is discussed, the force that can be tested against observation is identified, and it …

We investigate the vacuum energy of a scalar massless field confined in a Casimir cavity
moving in a circular equatorial orbit in the exact Kerr space-time geometry. We find that both …

We discuss the Casimir effect in a small cavity, moving in a circular orbit around an Ellis
wormhole. We show that the interplay between the spacetime geometry and the cavity …
