In this paper, we review some recent findings related to the Casimir effect. Initially, the
thermal corrections to the vacuum Casimir energy density are calculated, for a quantum …

We characterize the Casimir forces for the Dirac vacuum on free-fermionic chains with
smoothly varying hopping amplitudes, which correspond to (1+ 1)-dimensional [(1+ 1) D] …

The discussion of vacuum energy is currently a subject of great theoretical importance,
specially concerning the cosmological constant problem in General Relativity. From …

We show that the equation of null geodesics in spherically symmetric spacetimes in isotropic
coordinates is identical to the equation of light ray trajectories in isotropic media in flat …

We calculate the finite vacuum energy density of the scalar and electromagnetic fields inside
a Casimir apparatus made up of two conducting parallel plates in a general weak …

We calculate the renormalized vacuum energy density for a massless scalar field confined
between two nearby parallel plates formed by ideal uncharged conductors, placed very …

We show through Schwinger's approach that in a static weak gravitational background, the
Casimir Energy for a real massless scalar field obeying Dirichlet boundary conditions on …

In this work, we extend the analysis of the relativistic Dirac–Rosen–Morse problem in curved
space–time. For that, we consider the Dirac equation in curved space–time with line element …
