“…Later, Wang and Yu [43] demonstrated high-efficiency 3D atom localization in a three-level atomic system via measurement of the weak probe field absorption and obtained 100% atom localization probability in 3D space. Next, in another proposals, 100% probability of finding the atom at a particular position in 3D space has been reported in different atomic system [44][45][46][47][48][49] via measuring the absorption of a weak probe field, controlled spontaneous emission, and spatial interference.…”

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.

“…[50] Based on the absorption measurement of a probe field, a scheme of phasesensitive 3D atom localization has been presented in a driven four-level atomic system with two-fold lower levels and some charming polyhedron-, wave-, bowling-pin-, and tetrahedronlike localization structures have emerged. [51] The above studies remind us of an important question: Is it possible to realize subwavelength atom localization at room temperature?…”

A scheme is used to explore the behavior of three-dimensional (3D) atom localization in a Y-type hot atomic system. We can obtain the position information of the atom due to the position-dependent atom–field interaction. We study the influences of the system parameters and the temperature on the atom localization. More interestingly, the atom can be localized in a subspace when the temperature is equal to 323 K. Moreover, a method is proposed to tune multiparameter for localizing the atom in a subspace. The result is helpful to achieve atom nanolithography, photonic crystal and measure the center-of-mass wave function of moving atoms.

“…Zhu et al [37] discussed 3D atom localization behaviors in a double two-level atomic system based on spatial interference by application of three orthogonal standing-wave fields. Subsequently, some other proposals [38][39][40][41][42] for high-precision 3D atom localization are reported via measuring the absorption of a weak probe field, controlled spontaneous emission, and three-wave mixing. Inspired by these researches, here we propose an efficient 3D atom localization scheme based on the probe absorption measurement in a four-level diamond-configuration atomic system.…”

A new scheme for three-dimensional (3D) atom localization is proposed based on measuring the probe absorption spectra in a four-level diamond-configuration atomic system, in which the atom interacts with three orthogonal standing-wave laser fields. Due to spatial-dependent interaction between atom and fields, position information of the atom can be obtained by measuring the absorption spectra of the weak probe field. The results show that atom localization properties can be significantly improved and some interesting spatial localization structures such as double-layer lantern-like, single-layer lantern-like, gourd-like, cylinder-like, and ellipsoid-like patterns can be achieved when we adjust system parameters properly. Most importantly, we can find the atom at a particular position in 3D space with 100% probability under appropriate conditions.
