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 propose a scheme aimed at achieving spatiospectral control over spontaneous emission
within a four-level atom-light coupling system interacting with optical vortices carrying orbital …

The effect of spontaneously generated coherence (SGC) on spontaneous emission and
dynamical evolution of a microwave-driven four-level atomic system is studied. Interesting …

We investigate the features of the spontaneous emission spectra in a coherently driven cold
five-level atomic system by means of a radio frequency (rf) or microwave field driving a …

In a triple semiconductor quantum well structure coupled by two external fields, we
investigate the influence of atomic coherence induced by external fields and decay …

We investigate the two-dimensional (2D) and three-dimensional (3D) atom localization
behaviors via spontaneously generated coherence in a microwave-driven four-level atomic …

The feasibility of generating correlated photon pairs at variable frequencies is investigated.
For this purpose we consider the interaction of an off-resonant laser field with a two-level …

An approach to understanding the Fano absorption spectrum is presented in terms of the
complex spectral analysis. The absorption spectrum of an impurity embedded in semi …

We study the optical bistability and multistability in a defect structure doped with polaritonic
materials and three-level nanoparticles. It is realized that the threshold of optical bistability …

We investigate the fluorescence spectrum for a four-level atomic system, three levels of
which are coupled with two laser fields in a ladder configuration, and the upper-most level …
