Single atom in a superoscillatory optical trap

Communications Physics, 2023
Optical tweezers have become essential tools to manipulate atoms or molecules at a single particle level. However, using standard diffraction-limited optical systems, the transverse size of the trap is lower bounded by the optical wavelength, limiting ...

Feasibility of detecting single atoms using photonic bandgap cavities [PDF]

, 2004
We propose an atom-cavity chip that combines laser cooling and trapping of neutral atoms with magnetic microtraps and waveguides to deliver a cold atom to the mode of a fiber taper coupled photonic bandgap (PBG) cavity. The feasibility of this device for

Collisional trap losses of cold magnetically trapped Br atoms [PDF]

Physical Review A, 2014
Near-threshold photodissociation of Br$_2$ from a supersonic beam produces slow bromine atoms that are trapped in the magnetic field minimum formed between two opposing permanent magnets. Here, we quantify the dominant trap loss rate due to collisions with two sources of residual gas: the background limited by the vacuum chamber base pressure, and the ...

Atom trapping with a thin magnetic film [PDF]

, 2006
We have created a $^{87}$Rb Bose-Einstein condensate in a magnetic trapping potential produced by a hard disk platter written with a periodic pattern.

Reservoir-based deterministic loading of single-atom tweezer arrays

Physical Review Research, 2023
State-of-the-art individual-atom tweezer platforms have relied on loading schemes based on spatially superimposing the tweezer array with a cloud of cold atoms created beforehand.

Active-quadrupole interaction of Bessel beams and their influence on atoms

Journal of Taibah University for Science, 2020
This paper explains how the optical quadrupole interaction between a two-level neutral atom and two counter-propagating non-diffracting Bessel beams can exhibit interesting rotational characteristics.

A two-dimensional lattice of blue detuned atom traps using a projected Gaussian beam array

, 2013
We describe a new type of blue detuned optical lattice for atom trapping which is intrinsically two dimensional, while providing three-dimensional atom localization.

Near-resonant light scattering by an atom in a state-dependent trap

New Journal of Physics
There are an increasing number of experimental scenarios where near-resonant light is applied to atoms tightly trapped in far off-resonant optical fields, such as for quantum optics applications or for atom imaging.

Introduction to light forces, atom cooling, and atom trapping

, 1995
This paper introduces and reviews light forces, atom cooling and atom trapping. The emphasis is on the physics of the basic processes. In discussing conservative forces the semi-classical dressed states are used rather than the usual quantized field ...
