6 questions

  1. Wave-packet coherence of a harmonic oscillator radiating beyond the electric-dipole approximation: the quadrupole and higher-multipole extension of the 1948 Bauer–Jensen radiation-damping problem

  2. Completing the Daboul-Jensen theory of radiation reaction for a rotating charged sphere: relativistic consistency, pole structure, nonsmooth forcing, and admissible initial data

  3. Angular-Momentum Distributions and Shell Structure of Finite Fermi Systems Beyond the Smooth Thomas-Fermi Description

  4. Physical admissibility, detectability, and robustness of the singular modes in the Daboul–Jensen radiation-reaction formulation of electromagnetic scattering by a rigid, uniformly surface-charged spherical shell

  5. Angular correlation of successive cascade photons when fine or hyperfine splitting is comparable to the natural level width: general theory beyond equal diagonal widths and sharp final states, and experimental validation

  6. First-principles derivation of the total width Γ\Gamma of the giant dipole resonance
