Smooth cutoffs and analytic continuation in Casimir physics
Lucía N. Helou, Francisco D. Mazzitelli
Divergent series arising in the computation of Casimir energies admit two seemingly different treatments: a physically motivated regularization and subtraction procedure, and forma…
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…
Covariant extrinsic curvature expansion of the nonlocal effective action for a massless scalar field on a manifold with boundary
A. Boasso, C. D. Fosco, B. C. Guntsche +1
We study the nonlocal effective action of a massless scalar field defined on a flat manifold with a curved boundary. Using a heat-kernel approach, we derive a covariant expansion o…
Conformally-flat gravitational analogues to the Schwinger effect
S. A. Franchino-Viñas, F. D. Mazzitelli, S. Pla
We study particle creation for scalar fields in conformally flat spacetimes using resummed heat-kernel techniques. We make use of an analogy between quantum scalar fields in confor…
Shortcuts to adiabaticity, unexciting backgrounds, and reflectionless potentials
Fernando C. Lombardo, Francisco D. Mazzitelli
We analyze shortcuts to adiabaticity (STA) and their completions for the quantum harmonic oscillator (QHO) with time-dependent frequency, as well as for quantum field theory (QFT)…
Heat Kernels and Resummations: the Spinor Case
S. A. Franchino-Viñas, C. García-Pérez, F. D. Mazzitelli +2
Among the available perturbative approaches in quantum field theory, heat kernel techniques provide a powerful and geometrically transparent framework for computing effective actio…
