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 …

In Cosmology and in Fundamental Physics there is a crucial question like: where the elusive
substance that we call Dark Matter is hidden in the Universe and what is it made of? that …

We derive the gravitonic Casimir effect with nonidealized boundary conditions. This allows
the quantification of the gravitonic contribution to the Casimir effect from real bodies. We …

Doubt continues to linger over the reality of quantum vacuum energy. There is some
question whether fluctuating fields gravitate at all, or do so anomalously. Here we show that …

The influence of the gravity acceleration on the regularized energy-momentum tensor of the
quantized electromagnetic field between two plane-parallel conducting plates is derived. We …

Associated with the cosmic acceleration are the old and new cosmological constant
problems, recently put into the more general context of the dark energy problem. In broad …

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 …
