We have theoretically investigated two-dimensional atom localization using the absorption spectra of birefringence beams of light in a single wavelength *** atom localization is controlled and modified through tunneling effect in a conductive chiral atomic medium with absorption spectra of birefringent *** significant localization peaks are investigated in the left and right circularly polarized *** and double localized peaks are observed in different quadrants with minimum uncertainty and significant *** localized probability is modified by controlling birefringence and tunneling *** results may be useful for the capability of optical microscopy and atom imaging.

Spatial-dependent probe transmission based high-precision two-dimensional atomic localization

引用

Communications in Theoretical Physics 2021年第4期73卷 69-74页

作者： Muhammad Idrees Humaira Kalsoom bakth amin bacha Arif Ullah Li-Gang Wang Zhejiang Province Key Laboratory of Quantum Technology and Device Department of PhysicsZhejiang UniversityHangzhou 310027China Quantum Optics and Quantum Information Research Group Department of PhysicsUniversity of MalakandChakdara Dir(L)Khyber PakhtunkhwaPakistan Department of Mathematics Zhejiang Normal UniversityJinhua 321004China

Herein,we propose a scheme for the realization of two-dimensional atomic localization in aλ-type three-level atomic medium such that the atom interacts with the two orthogonal standing-wave fields and a probe *** of the spatially dependent atom-field interaction,the information about the position of the atom can be obtained by monitoring the probe transmission spectra of the weak probe field for the first time.A single and double sharp localized peaks are observed in the one-wavelength *** have theoretically archived high-resolution and high-precision atomic localization within a region smaller thanλ/25×λ/*** results may have potential applications in the field of nano-lithography and advance laser cooling technology.
