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…

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)…

Casimir Physics beyond the Proximity Force Approximation: The Derivative Expansion
César D. Fosco, Fernando C. Lombardo, Francisco D. Mazzitelli
We review the derivative expansion (DE) method in Casimir physics, an approach which extends the proximity force approximation (PFA). After introducing and motivating the DE in con…
