All-optical trapping of strongly coupled ions
[Text] / I. V. Krasnov, L. P. Kamenshchikov // Opt. Commun. - 2014. - Vol. 312. - P192-198, DOI 10.1016/j.optcom.2013.09.036. - Cited References: 21

Аннотация: We present and analyze a novel method of long-time ion trapping. This purely optical method is based on the action of rectified gradient forces on the ions in a 3D dissipative polychromatic optical superlattice which allows one to form super-deep potential wells for the ions. The ion trap presented ensures the possibility of long-time confinement both of single ions and small ordered ensembles of strongly coupled ions, i.e. ion (Coulomb) clusters. We demonstrate, by the numerical simulations of stochastic ion motion, the trapping of two-ion clusters for times exceeding several seconds. (C) 2013 Elsevier B.V. All rights reserved,

Conditions for formation and trapping of the two-ion Coulomb cluster in the dissipative optical superlattice
[Text] / I. V. Krasnov // Chin. Phys. B. - 2015. - Vol. 24, Is. 6. - Ст. 063701, DOI 10.1088/1674-1056/24/6/063701. - Cited References:22

Аннотация: Conditions have been studied under which a polychromatic optical superlattice can form and trap the Coulomb cluster of two strongly interacting ions. In our previous work (Krasnov I V and Kamenshchikov L P 2014 Opt. Comm. 312 192) this new all-optical method of obtaining and confining the Coulomb clusters was demonstrated by numerical simulations for special values of the optical superlattice parameters and in the case of Yb ions. In the present paper the conditions are explicitly formulated, under which the long-lived two-ion cluster in the superlattice cell is formed. The peculiarity of these conditions is the renormalization of the ion-ion Coulomb interaction. Notably, the renormalized Coulomb force is determined by the effective charge which depends on the light field parameters and can strongly differ from the "bare" ion charge. This result can be accounted for by the combined manifestation of the quantum fluctuations of optical forces, nonlinear dependence of these forces on the velocity, and non-Maxwellian (Tsallis type) velocity distribution of the ions in the optical superlattice. Explicit analytical formulas are also obtained for the parameters of the optical two-ion cluster.

Ions in the cell of the dissipative optical superlattice: cooling, trapping and Coulomb cluster formation

Аннотация: On the basis of numerical simulations and analytical calculations it is proved that the dissipative optical superlattice induced by the rectified gradient force is able to create and trap cold ion Coulomb clusters. In contrast to our previous work (2014 Opt. Commun. 312 192), in the present paper, we do not use the approximation of slow ions (SI), but take into account the non-conservative nature of the trapping force in the optical superlattice as well as the velocity dependence of the friction coefficient of ions and multiplicative nature of the quantum fluctuations of optical forces. It is shown that these factors significantly affect both the formations conditions of the ion Coulomb clusters and their characteristics. It is also demonstrated that their consequences can be well-described by the renormalized SI model. In this model, the electric ion charge is replaced by the effective charge which depends on the light field parameters.

Аннотация: Light trapping is a crucial prominence to improve the efficiency in thin film solar cells. However, last few years, plasmonic based thin film solar cells shows potential structure to improve efficiency in photovoltaics. In order to achieve the high efficiency in plasmonic based thin film solar cells, traditionally noble metals like Silver (Ag) and Gold (Au) are extensively used due to their ability to localize the light in nanoscale structures. In this paper, we numerically demonstrated the absorption enhancement due to the incorporation of novel plasmonic TiN nanoparticles on thin film Silicon Solar cells. Absorption enhancement significantly affected by TiN plasmonic nanoparticles on thin film silicon was studied using Finite-Difference-Time-Domain Method (FDTD). The optimal absorption enhancement 1.2 was achieved for TiN nanoparticles with the diameter of 100 nm. The results show that the plasmonic effect significantly dominant to achieve maximum absorption enhancement g(?) at longer wavelengths (red and near infrared) and as comparable with Au nanoparticle on thin film Silicon. The absorption enhancement can be tuned to the desired position of solar spectrum by adjusting the size of TiN nanoparticles. Effect of nanoparticle diameters on the absorption enhancement was also thoroughly analyzed. The numerically simulated results show that TiN can play the similar role as gold nanoparticles on thin film silicon solar cells. Furthermore, TiN plasmonic material is cheap, abundant and more Complementary Metal Oxide Semiconductor (CMOS) compatible material than traditional plasmonic metals like Ag and Au, which can be easy integration with other optoelectronic devices. © 2017 Elsevier B.V.

A study of metastable ion Coulomb crystals in a polychromatic all-optical trap: Decay process analysis by using supercomputer simulations
/ I. V. Krasnov, L. P. Kamenshchikov // Eur. Phys. J. D. - 2019. - Vol. 73, Is. 10. - Ст. 224, DOI 10.1140/epjd/e2019-100252-5

Аннотация: Abstract: Metastable ion Coulomb crystal (ICC) in the polychromatic optical superlattice (OSL) created by so-called rectified gradient forces is studied. Our analysis is based on the numerical solution of the nonlinear stochastic differential equations taking into account the trapping and dissipative forces, their quantum fluctuations, and Coulomb repulsion of ions. The key question is how long will this metastable highly ordered crystalline structure persist. The critical parameter determining the ICC destruction times td is the OSL period L (at fixed intensity values of the optical fields). Our simulations demonstrate that td of the ICC, consisting of several tens of mercury ions, experiences giant changes (by four orders of magnitude) at relatively slight variations of the optical superlattice period L in the range from 0.35 to 0.70 mm. We have shown that the dependence td (L) can be approximated by the Arrhenius-like equation with an effective activation energy which is nonlinearly dependent on the OSL period L. These results explain the ultrahigh sensitivity td (L) to the OSL period L and show how to adjust L to ensure all-optical confinement of ICC in the OSL from a fraction of a second to one and half minutes.
