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,

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: We theoretically consider a novel type of the optical dark trap (ODT) for resonant atoms and ions. This trap is based on the rectified gradient forces acting on particles in the field of a combination of multiple bichromatic cosine-Gauss optical beams (CGBs). Such a bichromatic ODT can have a depth significantly exceeding the depth of the typical dark optical traps and is comparable with the depth of magneto-optical traps (similar to 1 K).
