“…In Ref. [94], the frequency-dependent polarizabilities between the hyperfine states of alkali-metal atoms were used to identify "magic" wavelengths for which ns and np 1/2,3/2 atomic levels have the same ac-Stark shifts, enabling state-insensitive optical cooling and trapping [100]. The magic wavelength is determined as the wavelength at which the Stark shifts of the upper and lower level for a specific transition are the same.…”

All-order extensions of relativistic atomic many-body perturbation theory are described and applied to predict properties of heavy atoms. Limitations of relativistic many-body perturbation theory are first discussed and the need for all-order calculations is established. An account is then given of relativistic all-order calculations based on a linearized version of the coupled-cluster expansion. This account is followed by a review of applications to energies, transition matrix elements, and hyperfine constants. The need for extensions of the linearized coupled-cluster method is discussed in light of accuracy limits, the availability of new computational resources, and precise modern experiments. For monovalent atoms, calculations that include nonlinear terms and triple excitations in the coupled-cluster expansion are described. For divalent atoms, results from second-and third-order perturbation theory calculations are given, along with results from configuration-interaction calculations and mixed configuration interaction-many-body perturbation theory calculations. Finally, applications of all-order methods to atomic parity nonconservation, polarizabilities, C 3 and C 6 coefficients, and isotope shifts are given.

“…Systematic experimental studies of cavity-mediated laser cooling have subsequently been reported by Rempe and co-workers [3][4][5][6], Vuletić and co-workers [7][8][9][10], and others [11,12]. Recent atom-cavity experiments access an even wider range of experimental parameters by replacing conventional high-finesse cavities [13,14] with optical ring cavities [15,16] and tapered nanofibers [17,18] and by combining optical cavities with atom-chip technology [19,20], atomic conveyer belts [21,22], and ion traps [23].…”

The cooling rate for cavity-mediated laser cooling scales as the Lamb-Dicke parameter η squared. A proper analysis of the cooling process hence needs to take terms up to η 2 in the system dynamics into account. In this paper, we present such an analysis for a standard scenario of cavity-mediated laser cooling with η 1. Our results confirm that there are many similarities between ordinary and cavity-mediated laser cooling. However, for a weakly confined particle inside a strongly coupled cavity, which is the most interesting case for the cooling of molecules, numerical results indicate that more detailed calculations are needed to model the cooling process accurately.

“…Some of them involve using some external laser fields which exert a confining force to the atom, something that has been successfully realized in recent experiments [19,20,21]. In a far-off resonant trap (FORT) this is achieved by employing a far-off resonant trapping beam along the cavity axis.…”

“…In order to overcome these problems, several strategies to trap an atom in a cavity have been put forward [11,12,13,14,15,16,17,18,19,20,21].

The aim of this work is to find ways to trap an atom in a cavity. In contrast to other approaches we propose a method where the cavity is basically in the vacuum state and the atom in the ground state. The idea is to induce a spatial dependent AC Stark shift by irradiating the atom with a weak laser field, so that the atom experiences a trapping force. The main feature of our setup is that dissipation can be strongly suppressed. We estimate the lifetime of the atom as well as the trapping potential parameters and compare our estimations with numerical simulations.
