| الوصف: | We report on the realization and characterization of a novel magic-wavelength nanofiber-based two-color optical dipole trap that allows us to generate a periodic one-dimensional array of trapping sites with a spacing significantly smaller than half of the resonant wavelength of the cesium D2-line. To this end, we launch a blue-detuned partial standing wave and two red-detuned light fields through the nanofiber. We demonstrate the trapping of atoms in the array and characterize the resulting trap configuration by measuring the trap frequencies in three directions and observe good agreement with theoretical predictions. The implementation of this nanofiber-based optical interface with magic trapping wavelengths and sub-$\lambda/2$ spacing is an important step towards the exploration of novel collective radiative effects such as selective radiance in 1D atomic arrays.
