Effect of Self-Interaction on Feynman's Interpretation of the Lamb Shift Open
We derive Bethe's formula for the Lamb shift by extending Feynman's suggestion that the shift could be interpreted as the change, due to the presence of the atom, in electromagnetic field energy. This approach is based on measurable quanti…

Scattering of identical particles by a one-dimensional Dirac delta function barrier potential: The role of statistics Open
Scattering of non-interacting, identical bosons or fermions by a one-dimensional Dirac delta function barrier potential underlines the importance of the role of statistics (that is, whether the particles obey Fermi–Dirac or Bose–Einstein s…

Atom Interferometry in the Presence of an External Test Mass Open
The influence of an external test mass on the phase of the signal of an atom interferometer is studied theoretically. Using traditional techniques in atom optics based on the density matrix equations in the Wigner representation, we are ab…

Vertical dipole above a dielectric or metallic half space: Energy-flow considerations Open
The emission pattern from a classical dipole located above and oriented perpendicular to a metallic or dielectric half space is calculated for a dipole driven at constant amplitude. Emphasis is placed on the fields in the metal or dielectr…
