One of the key frameworks for develo** the theory of light–matter interactions in modern
optics and photonics is quantum electrodynamics (QED). Contrasting with semiclassical …

In the wide realm of applications of quantum electrodynamics, a non-covariant formulation of
theory is particularly well suited to describing the interactions of light with molecular matter …

Chiroptical and optical activity effects involve differential interactions between matter and
light. Generally this involves chiral molecules absorbing or scattering right-and left-handed …

We have experimentally generated a vortex six-wave mixing (SWM) signal via a photonic
band gap structure in a hot atomic ensemble. The output SWM carrying orbital angular …

The second harmonic generation in the bulk of an isotropic chiral liquid with spatial or
temporal nonlocality of its quadratic response is studied analytically. The fundamental …

Hyper-Rayleigh scattering (HRS) is an incoherent mechanism for optical second harmonic
generation. The frequency-doubled light that emerges from this mechanism is not emitted in …

For the first time we have obtained the analytical expressions describing the spatial
distribution of the polarization of a second harmonic beam's light field reflected from the …

The traditional multiwave mixing setups are always complicated because multiple laser
beams are involved, and they are required to be aligned into certain spatial configurations to …

We present the first gauge-origin independent calculations of the circular intensity difference
(CID) in electric-field-induced second-harmonic generation (EFISHG), including all …

Hyper-Rayleigh scattering (HRS) is an incoherent variant of second harmonic generation.
The theory involves terms of increasing order of optical nonlinearity: for molecules or unit …
