A magneto-optical trap (MOT) at narrow transition offers lower temperature and hence is the key for producing a high phase density atomic cloud and subsequently quantum degeneracy with a large number of atoms for many elements. In this paper, we descri…
We theoretically study the optical bistability and second-order sideband generation (SSG) in an optical cavity having photothermal effect in our paper. Using the perturbation method, we give an explicit analytical expression for SSG, showing a conversi…
One of the challenges in calculating the opacity of dense plasmas is the difficulty in consistently modeling electrons bound to nuclei and those that exist within the continuum of free states in electronic structure models. We address this issue by ada…

An R-matrix calculation is reported for low energy electron collision with the beryllium oxide (BeO) molecule at its equilibrium bond length a0 for incident energies below 15 eV. Using a suitably constructed model to represent the BeO target, detailed…
We present exact analytic formulae which describe the interaction of multistate quantum systems possessing the Wigner–Majorana and Morris–Shore dynamic symmetries with a train of pulses. The pulse train field can be viewed as repeated interactions of t…
In this paper, we investigate the nonclassicality and non-Gaussianity of a coherent superposed quantum state (CSQS) which is obtained by applying a coherent superposition of field annihilation (a) and creation () operators, to a classical coherent sta…
The aim of the present theoretical work is the characterization of argonium, namely, the molecular ions and , revealed in the last decade in the Crab Nebula and the PKS 1823-211 galaxy. The intent is to scrutinize the radiative processes of associatio…
Collective excitation modes in a general 3D homogenous spin-3/2 Fermi gas with spin-dependent contact interactions are investigated by two-particle Green’s functions and diagram techniques. Energy spectra for two branches of charge-density waves and th…
We use biorthogonal basis consisting of the ‘right’ and ‘left’ eigenvectors of the effective non-Hermitian Hamiltonian of a three-level system driven by a bi-chromatic field, and resolve the probe absorption spectrum into components corresponding to t…
