High-precision three-dimensional atom localization via probe absorption at room temperature

Abstract

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.

Microwave enhanced precision in 2D and 3D atom localization at nonzero temperatures

“…Until now, we have discussed the 2D and 3D precision position measurement of atoms which are either stationary (T = 0 K) or at low temperature(T = 5 K). However, the low temperature experimental setups are too complicated [43] and limit some practical applications like atom lithography at room temperature [49]. To address this issue, we explore the conditional position probability distribution of an 8(a)) and similarly a small isosphere is found in the first octant of the 3D isosurface plot (figure 8(b)).…”

“…Recently, Wahab et al used a four-level atomic system for 2D and 3D atom localization [39]. In addition, many other atomic systems have been proposed for precision position measurement in 3D subspace [40][41][42][43][44][45][46][47].…”

“…We demonstrate that the 100% detection probability in a single sub-wavelength space is retained even after inculcation of the Doppler effect. The Doppler broadened atom localization has been subject of only a few proposals [43,48,49] and none of these studies presented a detailed comparison between the 2D/3D localization behavior of stationary and moving atoms. Therefore, our five-level X-type system can be experimentally implemented for atoms confined in a magneto-optical trap (MOT) as well as hot vapor cells.…”

High-precision three-dimensional Rydberg atom localization in a four-level atomic system*

“…Several highprecision 3D atom localization schemes have been proposed by measuring the probe absorption, spontaneous emission, and Kerr nonlinearity. [19][20][21][22][23][24] Even though there are many efficient schemes for atom localization, until now only a few Rydberg atom localization have been reported. [25] The large size of the Rydberg atom makes it a good candidate for studying the quantum coherence phenomena.…”

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

“…Quite recently, several schemes [49][50][51] have been proposed to investigate the atom localization in three dimensions. Qi et al [52] studied the localization and structure by the transparency of electromagnetic induction, a variety of atom localization patterns in the subspaces could be obtained via changing the system parameters.…”
