Near dipole-dipole interaction induced control of high-precision three-dimensional atom localization via probe absorption in a four-level phase-coherent atomic medium

Aniket Banerjee, Pradipta Panchadhyayee, Bibhas Kumar Dutta

It is newly proposed that the presence of the near dipole-dipole (NDD) interaction effect in an optically dense atomic ensemble may be very useful for controlling high-precision atom localization. In the present work based on observing the NDD effect-induced space-dependent-absorption of a weak probe field operating in a partially closed four-level Y-type atomic system, we have shown the NDD parameter being an efficient control knob along with the other system parameters for easier optimization of the localization pattern with enhanced detection probability in three-dimensional (3D) space. Controlling localization patterns at lower and larger values of NDD parameter is discussed at different physical conditions. In the present model, we mention that the maximum detection probability of the atom is found with the spatial resolution limit having localization volume nearly of the order of [Formula: see text]. The efficacy of the present model is in finding its application in atom nanolithography and atom imaging, which are important for quantum information processing and technology.

Efficient control of high-precision three-dimensional atom localization via probe absorption in a five-level phase-coherent atomic system

Aniket Banerjee, Pradipta Panchadhyayee, Bibhas Kumar Dutta

Abstract We propose a new scheme for high-precision three-dimensional (3D) atom localization by observing the spatially modulated absorption of a weak probe field operating in a partially closed-loop dependent five-level atomic system. Different spatial structures of localization patterns are presented by controlling the Rabi frequency, detuning, and field-induced collective phase-coherence with a variety of superposed standing wave field configurations. Our results highlight that 100% detection probability of atom is possible in the present model in many ways with high precision measurement of spatial absorption. It has been shown that, in the presence of standing wave fields, position information of the atom with maximum detection probability can be efficiently controlled by employing the travelling-wave field in the system. In the present work, we note that the maximum detection probability of the atom is attainable with the limit of spatial resolution better than λ/50. The efficacy of the present model is to find its application in atom nanolithography and atom-imaging having importance in quantum information processing.

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

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.
