Controlling two dimensional diatomic molecular localization with probe and standing wave fields.

The localization of di-atomic molecules is significantly modified and controlled in a four-levels scheme using probe and standing wave control fields. The study investigates the localization peaks of both single and double di-atomic molecules under different controlling parameters and directions of the driving fields. By altering the directions and phases of the driving fields for standing waves, the localized peaks of di-atomic molecules can be shifted between quadrants. The localization of the two di-atomic molecules is manipulated with precise position and minimum uncertainty measurement within a wavelength domain along, kx and ky plane. The reported molecular resolution is reported to more than λ / 3 × λ / 8 along kx and ky plane. The theoretical investigation shows potential application in nano-lithography and diatomic molecular trapping. [ABSTRACT FROM AUTHOR]
