Two-dimension atom nano-lithograph via atom localization

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

“…As can be seen from Figs. 3(a) and 5(a), this kind of high-precision and high-resolution atom localization cannot be observed in those schemes which employ only single-channel spontaneous emission [40][41][42][43][44]. When the frequency detuning is slightly increased, i.e., δ λ = 10, these enhanced localization peaks are strongly suppressed, as shown in Fig.…”

“…A method for atom nanolithography based on 2D atom localization is reported in Ref. [41] by application of two orthogonal standing-wave fields. Ivanov and Rozhdestvensky [42] proposed a four-level tripod system for 2D atom localization by measuring the population of the atom in two standing-wave fields based on EIT.…”

“…This leads us to pose another question: If a similar atomic system interacts with two orthogonal standing-wave fields rather than with two traveling-wave coupling fields, what will be the resulting atom localization when the atom passes through the standingwave fields? Although 2D atom localization has been investigated in some schemes [39][40][41][42][43][44], most discussions are limited to considering the spontaneous emission in a single decay channel. In contrast, in this paper, we focus on the measurement of spontaneous emission from two coherent decay channels, and thus we investigate 2D atom localization.…”

Precision localization of single atom via spontaneous emission in three dimensions

“…However, to the best of our knowledge, the maximum probability of finding an atom at a particular position in a wavelength domain is very low in these schemes; see, e.g., in the recent work [34], the maximum probability of finding an atom at a particular position in a wavelength domain is 1/8. In order to deal with the above problem, here we put forward a scheme to realize efficient 3D atom localization based on the measurement of spontaneous emission in a three-level atomic system.…”

“…Subsequently, related 2D localization schemes [27][28][29][30][31][32][33] have been studied by Wan, Ding, Qamar, and their coworkers via controlled spontaneous emission, probe absorption and gain, and interacting double-dark resonances, and Raman-driven coherence. In addition, atom nano-lithography based on 2D atom localization has been achieved by Jin et al in [34].…”
