Superradiance and anomalous hyperfine splitting in inhomogeneous ensembles
Petar Andrejić, Adriana Pálffy
Collective effects in the interaction of light with ensembles of identical scatterers play an important role in many fields of physics. However, often the term ``identical'' is not…

Convergent measure of focal extent, and largest peak intensity for non-paraxial beams
Petar Andrejić
Second moment beam widths are commonly used in paraxial optics to define the focal extent of beams. However, second moments of arbitrary beams are not guaranteed to be finite. I pr…

Lorentz transformation of electromagnetic pulses derived from Hertz potentials
Petar Andrejić
Electric and magnetic Hertz potentials are a formalism for obtaining solutions of Maxwell's equations from solutions of the inhomogeneous wave equation, with polarisation and magne…
