Abstract Sir Peter Knight is a pioneer in quantum optics which has now grown to an
important branch of modern physics to study the foundations and applications of quantum …

A theoretical investigation is carried out into the effect of spontaneously generated
coherence on the Kerr nonlinearity of general three-level systems of Λ, ladder, and V-shape …

We show that the quantum interference between two spontaneous emission channels can
be greatly enhanced when a three-level V-type atom is placed near plasmonic …

We demonstrate how the anisotropy of the vacuum of the electromagnetic field can lead to
quantum interferences among the decay channels of close lying states. Our key result is that …

By investigating the third-order nonlinearity of a four-level ladder-type atomic system, it is
found that, with spontaneously generated coherence (SGC) present, the nonlinear …

A scheme is proposed for two-dimensional atom localization in the subwavelength domain
via controlled spontaneous emission. We consider a five-level M-type atomic system …

We consider nondegenerate pump-probe spectroscopy of V systems under conditions such
that interference among decay channels is important. We demonstrate how this interference …

We study theoretically the effects of a plasmonic nanostructure on the linear absorption and
dispersion spectrum of a four-level double-V-type quantum system. In the quantum system …

Spontaneous emission of an atom with two close upper levels and one lower level in a
multilayer dielectric medium, and quantum interference between transitions from the upper …

We study the absorption and dispersion properties of a Λ-type atom that decays
spontaneously near the edge of a photonic band gap (PBG). Using an isotropic PBG model …
