“… 44 have studied an entropic formalism for understanding the free dynamics of Gaussian beams when subjected to lenses, while also considering its extension to super-Gaussian beams. Besides, atomic microscopy regulated by the absorption spectrum of a weak probing field composed of two reinforced super-Gaussian beams is found to be significant in advanced high-tech and nano-lithographic applications 45 . It is now evident that the super-Gaussian fields have been studied significantly in various fields, however, they have not yet been investigated in the case of the dynamics of open quantum systems.…”

The preservation of quantum correlations requires optimal procedures and the proper design of the transmitting channels. In this regard, we address designing a hybrid channel comprising a single-mode cavity accompanied by a super-Gaussian beam and local dephasing parts based on the dynamics of quantum characteristics. We choose two-level atoms and various functions such as traced-distance discord, concurrence, and local-quantum uncertainty to analyze the effectiveness of the hybrid channel to preserve quantum correlations along with entropy suppression discussed using linear entropy. The joint configuration of the considered fields is found to not only preserve but also generate quantum correlations even in the presence of local dephasing. Most importantly, within certain limits, the proposed channel can be readily regulated to generate maximal quantum correlations and complete suppression of the disorder. Besides, compared to the individual parts, mixing the Fock state cavity, super-Gaussian beam, and local dephasing remains a resourceful choice for the prolonged quantum correlations’ preservation. Finally, we present an interrelationship between the considered two-qubit correlations’ functions, showing the deviation between each two correlations and of the considered state from maximal entanglement under the influence of the assumed hybrid channel.

“…In quantum optics, localization is based on employing atomic coherence to determine the position of the atom to a precision smaller than the wavelength of the light being used [1][2][3][4]. Atom localization has wide range of applications in the field of surface scattering, heterogeneous catalysis, atomic microscopy, surface physics, trapping of atoms and Bose-Einstein condensation [5][6][7][8][9].…”

Diatomic localization in a four level system is investigated by using absorption spectrum of Compton scattering beam. Information of diatomic molecules is obtained from absorption spectrum of Compton scattering beam through superposition of driving fields. Joint sharp absorption peaks are observed in a full wavelength domain, which exhibit localization of diatomic molecules. A single, double, and even many molecules are controlled in a wavelength domain of a two dimensional plane. The localization peaks have minimum uncertainty spread and have high probability of existence of the molecule within a full wave length domain. This study is hoped to be used in modern nanolithography, Bose-Einstein condensation, and Laser cooling.
