Three-dimensional atom localization via spontaneous emission in a four-level atom

Abstract

We investigate high-precision three-dimensional (3D) atom localization in a coherently-driven, fourlevel atomic system via spontaneous emission. Space-dependent atom-field interactions allow atomic position information to be obtained by measuring spontaneous emission. By properly varying system parameters, atoms within a certain range can be localized with nearly a probability of 100% and a maximal resolution of ~ 0.04λ. This scheme may be useful for the high-precision measurement of the center-of-mass wave functions of moving atoms and in atom nanolithography.

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.

Three-dimensional atom localization with high-precision and high-resolution via a microwave field in an atomic system

Jiayu Liu, Hai-Hua Wang, Lei Wang +3 more

Abstract A scheme for three-dimensional (3D) atom localization with high-precision and high-resolution is proposed and its control is studied in a four-level atomic system driven by an additional microwave field. Because of the spatial dependent interaction between atoms and standing wave fields, the atoms can be localized in a domain with widths as small as 0.014 λ by appropriately adjusting the system parameters. The probe absorption spectrum of the atomic system gives the position information of the atoms and different evolution patterns of the localization structures in this study. The population distribution and its 3D localization structures can be easily adjusted by parameters of the microwave field, which can achieve a 100% probability of observing the atom in a specific space and the accuracy with the value of 0.014 λ . Compared with 1D or 2D localizations, 3D localization can further improve the precision of position measurement and develop its spatial resolution, which may produce a wider variety of practical applications with high precision requirement.

High-dimensional atom localization via spontaneously generated coherence in a microwave-driven atomic system

Zhiping Wang, Jinyu Chen, Benli Yu

We investigate the two-dimensional (2D) and three-dimensional (3D) atom localization behaviors via spontaneously generated coherence in a microwave-driven four-level atomic system. Owing to the space-dependent atom-field interaction, it is found that the detecting probability and precision of 2D and 3D atom localization behaviors can be significantly improved via adjusting the system parameters, the phase, amplitude, and initial population distribution. Interestingly, the atom can be localized in volumes that are substantially smaller than a cubic optical wavelength. Our scheme opens a promising way to achieve high-precision and high-efficiency atom localization, which provides some potential applications in high-dimensional atom nanolithography.

Two-dimensional atom localization via spontaneous emission in a coherently driven five-level M-type atomic system

Chunling Ding, Jiahua Li, Zhiming Zhan +1 more

A scheme is proposed for two-dimensional atom localization in the subwavelength domain via controlled spontaneous emission. We consider a five-level M-type atomic system interacting with two orthogonal standing-wave laser fields and the vacuum of the radiation field. The interaction of the atom with space-dependent standing-wave fields can provide information about the position of the atom passing through, thus leading to atom localization. It is found that the localization is significantly improved due to the interference effect between the spontaneous decay channels and the dynamically induced quantum interference generated by the two standing-wave fields. By properly varying the system parameters, we can achieve high-precision and high-resolution atom localization.

High-precision three-dimensional atom localization via phase-sensitive absorption spectra in a four-level atomic system

Duo Zhang, Rong Yu, Zhaoyu Sun +2 more

Abstract We propose a new scheme for highly efficient three-dimensional (3D) atom localization in a coherently driven closed-loop four-level atomic system via measuring the probe absorption of the weak field. Due to the spatially dependent atom–field interaction, the absorption spectra of the weak probe laser field carry the information about the atomic position. By solving the density-matrix equations of motion and properly modulating the system parameters such as the probe detuning, the relative phase of three driving fields, and the intensity of the control and microwave fields, we can realize high-precision and high-resolution 3D atom localization. Furthermore, we can find the atom at a certain position with 100% probability under appropriate conditions, and then we employ the dressed-state analysis to explain qualitatively the reason of high-precision 3D atom localization.

High-precision three-dimensional atom localization via Kerr nonlinearity

Yin Hong, Zhiping Wang, Benli Yu

Recently, there have been many schemes for achieving high-dimensional atom localization via measuring the first-order linear susceptibility. Here, we present a new scheme for high-precision three-dimensional (3D) atom localization in a three-level atomic system based on the Kerr nonlinearity, which refers to the real part of the third-order nonlinear susceptibility. Due to the space-dependent atom-field interaction, the position information of the atom can be determined by measuring Kerr nonlinearity in 3D space. Interestingly, by properly varying the parameters of the system, we find that there is only a small sphere in 3D space, which means the probability of finding the atom at a particular position can be 100%. Our scheme not only shows a new way to achieve high-precision and high-efficiency 3D atom localization but also provides some potential applications in high-dimensional atom nanolithography.
