“…A method for microscopic trapping and guiding individual atoms along a nanofiber has been proposed [1]. An optical technique for loading atoms into quantum adsorption states of a dielectric surface has been suggested [2,3]. The possibility to control and manipulate individual atoms near surfaces can find applications for quantum information [6,7,8] and atom chips [9,10].…”

“…In the theoretical treatments of Refs. [2,3], the quantum electrodynamic enhancement of spontaneous emission due to the mode modification was completely neglected, and a set of equations with phenomenologically added decay terms was used for describing the dynamics of the loading process. A more rigorous theory requires a deeper knowledge of the structure of the decay equations and the magnitudes of the decay coefficients for the translational levels of the atom.…”

We study spontaneous radiative decay of translational levels of an atom in the vicinity of a semi-infinite dielectric. We systematically derive the microscopic dynamical equations for the spontaneous decay process. We calculate analytically and numerically the radiative linewidths and the spontaneous transition rates for the translational levels. The roles of the interference between the emitted and reflected fields and of the transmission into the evanescent modes are clearly identified. Our numerical calculations for the silica-cesium interaction show that the radiative linewidths of the bound excited levels with large enough but not too large vibrational quantum numbers are moderately enhanced by the emission into the evanescent modes and those for the deep bound levels are substantially reduced by the surface-induced red shift of the transition frequency.

“…For some applications, it might be of interest to control the adsorption in the presence of a vapor at saturated vapor pressure. Resonant light seems to be a good candidate to manipulate the number and position of atoms on the surface [8][9][10][11][12].…”

Selective reflection technique as a probe to monitor the growth of metallic thin film on dielectric surfaces

et al. 2013

View full text Add to dashboard Cite

Controlling thin film formation is technologically challenging. The knowledge of physical properties of the film and of the atoms in the surface vicinity can help improve control over the film growth. We investigate the use of the well-established selective reflection technique to probe the thin film during its growth, simultaneously monitoring the film thickness, the atom-surface van der Waals interaction and the vapor properties in the surface vicinity.

“…This is the key for various experiments with cold atoms in which surface properties are investigated and exploited. Important examples are dispersive potentials due to van der Waals and Casimir forces [20], but also the fascinating idea of investigating bound surface-atom states by laser-induced quantum adsorption [21,22], which is the analogue to photo-association of atoms. The crucial question herein is if atoms can be trapped in these highly excited bound states and if these traps can be tailored by a suitable structuring of the surface.…”

Towards surface quantum optics with Bose–Einstein condensates in evanescent waves

et al. 2009

View full text Add to dashboard Cite

We present a surface trap which allows for studying the coherent interaction of ultracold atoms with evanescent waves. The trap combines a magnetic Joffe trap with a repulsive evanescent dipole potential. The position of the magnetic trap can be controlled with high precision which makes it possible to move ultracold atoms to the surface of a glass prism in a controlled way. The optical potential of the evanescent wave compensates for the strong attractive van der Waals forces and generates a potential barrier at only a few hundred nanometers from the surface. The trap is tested with 87 Rb Bose-Einstein condensates (BEC), which are stably positioned at distances from the surfaces below one micrometer.
