Special Issue Information

Dear Colleagues,

The interaction between matter and external fields results in a wide range of exotic quantum phenomena involving a rich dynamical interplay of electrons, protons, and photons. These interactions can lead to the formation of new quasiparticles such as exciton–polaritons, plasmon–polaritons, phonon–polaritons, and plexitons, each of them with distinct properties. In recent years, there have been continuous efforts to understand such emergent properties using a wide variety of tailored fields, including static electric fields, optical near fields, lasers, and confined electromagnetic fields (e.g., optical and optomechanical cavities), as well as use them to manipulate matter's physical, optical, chemical, and transport properties. However, many of these phenomena remain to be fully understood and may have untapped potential for novel technologies.

In this regard, mechanistic insights obtained through theoretical or computational investigations may provide new strategies to engineer materials or even new quantum devices. This Special Issue focuses on theoretical investigations of matter (atoms/molecules/materials) under static electric fields, intense lasers, plasmonic, or confined electromagnetic fields.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Atoms is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1500 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Current inspection rigorously explores the tuning of a few relevant nonlinear optical (NLO)properties of GaAs quantum dot (QD) under the stewardship of Gaussian noise-anharmonicity interplay. The NLO properties explored are total optical absorption coefficient (TOAC), total optical refractive index change (TORIC), nonlinear optical rectification (NOR), second harmonic generation (SHG), third harmonic generation (THG), DC-Kerr effect (DCKE), electro-absorption coefficient (EAC), group index (GI)and optical gain (OG). The route of application of noise (additive/multiplicative) to the QD, as well as the symmetry (odd/even) of the anharmonicity, influence the aforesaid NLO properties. These NLO properties exhibit steadfast growth, steadfast fall, maximization, minimization and saturation. The outcomes of the inspection appear to be quite pertinent in the context of the immense technological demand of QD, taking into account the combined impact of anharmonicity and noise. Full article
