Van der Waals interaction at short and long distances: a pedagogical path from stationary to time-dependent perturbation theory
L. Saba, C. D. Fosco
The van der Waals interaction between neutral atoms is typically studied using stationary perturbation theory for the short-distance (London) limit, while long-distance (Casimir-Po…
Lamb Shift of a Static Atom Facing a Rotating Surface
César D. Fosco, Fernando C. Lombardo, Francisco D. Mazzitelli
We study how the Lamb shift of a static atom is modified when a nearby planar body rotates rigidly about its normal while the atom is held at a fixed distance . We derive a gene…
Pair creation amplitudes for a real scalar field coupled to a time-dependent surface in d+1 dimensions
C. D. Fosco, B. C. Guntsche
We study the pair creation phenomenon for a real scalar field in the presence of a surface that undergoes time-dependent deformations, while imposing Dirichlet-like boundary c…
Parity-dependent Casimir forces and Hall currents for a confined Dirac field
Aitor Fernández, César D. Fosco
We study a massless Dirac field subjected to two alternative boundary conditions on two parallel thin walls, in d + 1 dimensions. The two configurations correspond to the system be…
Quantum dissipative effects for a real scalar field coupled to a time-dependent Dirichlet surface in d+1 dimensions
B. C. Guntsche, C. D. Fosco
We study the Dynamical Casimir Effect (DCE) for a real scalar field in dimensions, in the presence of a mirror that imposes Dirichlet boundary conditions and undergoes t…
Quantum dissipative effects for a real scalar field coupled to a dynamical Neumann surface in d+1 dimensions
C. D. Fosco, B. C. Guntsche
We study dissipative effects for a system consisting of a massless real scalar field satisfying Neumann boundary conditions on a space and time-dependent surface, in d+1 dimensions…
