Abstract

Abstract A new scheme for three-dimensional (3D) atom localization is proposed, in which the atomic system is driven by three orthogonal standing-wave lasers. Because of the space-dependent atom–field interaction, the position probability distribution of the atom can be directly determined by measuring the probe absorption. It is found that, by properly varying the parameters of the system, the probability of finding the atom in 3D space can be almost 100%. Our scheme opens a promising way to achieve high-precision and high-efficiency 3D atom localization, which provides some potential applications in laser cooling or atom nano-lithography via atom localization.

Precision localization of single atom via phase-dependent quantum coherence in three dimensions

Zhiping Wang, Benli Yu

Abstract We present a new scheme for high-efficiency three-dimensional (3D) atom localization in a four-level atomic system via measuring the populations in two excited states. Owing to the space-dependent atom–field interaction, the position probability distribution of the atom passing through the standing waves can be directly determined by measuring the populations in two excited states. It is found that the phase-sensitive property of the atomic system reduces the uncertainty in the position measurement of the atom. In particular, the probability of finding the atom in 3D space can be almost 100% via properly varying the parameters of the system. Our scheme opens a promising way to achieve high-precision and high-efficiency 3D atom localization, which provides some potential applications in the atom nanolithography via 3D atom localization.

High-precision three-dimensional atom localization in a three-level pump–probe atomic system

Fanong Zheng, Qiang Ge, Xinglin Wang

We propose a new scheme for three-dimensional (3D) atom localization controlled by incoherent pump in a three-level Λ-type atomic system. The spatial position information of an atom in 3D space can be achieved via measuring probe gain and absorption when the atom passes through three mutually perpendicular standing-wave fields. It is found that high-detecting-probability and high-precision 3D atom localization can be obtained via properly adjusting the relevant parameters in the presence of the combination of a traveling-wave field and three orthogonal standing-wave fields. Furthermore, it is also shown that the incoherent pumping field can switch the localization patterns from the probe-gain sphere to the probe-absorption sphere and enhance 3D atom-localization precision.

Three-dimensional atom localization in a five-level M-type atomic system

Yihong Qi, Fengxue Zhou, Ting Huang +2 more

By using three mutually perpendicular standing-wave fields, we propose a scheme for three-dimensional (3D) subwavelength atom localization in a five-level M-type atomic system. Based on the electromagnetically induced transparency, position probability distribution of the atom in 3D space could be determined via measuring the probe absorption which is proportional to the filter function. It is shown that patterns of 3D atom localization depends sensitively on the coupling schemes of the standing-wave fields. When the standing-wave fields couple three different transitions, the same atom localization patterns are formed in the eight subspaces of the 3D space. While all the standing-wave fields are applied on one transition, we can realize different atom localization patterns in the eight subspaces. From the view of the xy plane, various symmetric or asymmetric atom localization patterns could be formed at different z positions by adjusting the parameters of the laser fields.

Abstract We present a new scheme for three-dimensional (3D) atom localization in a four-level atomic system based on the interference of double-dark resonances. Owing to the space-dependent atom-field interaction, the position probability distribution of the atom can be directly determined by measuring the probe absorption. It is found that, by properly varying the parameters of the system, the probability of finding the atom in 3D space can be 1/2. Our scheme opens a promising way to achieve high-precision and high-efficiency 3D atom localization, which provides some potential applications in the atom nanolithography via 3D atom localization.
