| 概 要 |
This talk will present our on-going effort to control the dipole-dipole interaction between cold Rydberg atoms. In our experiment, we trap individual atoms in two-dimensional arrays of optical tweezers [Nogrette, Phys. Rev. X 4, 021034 (2014)] separated by few micrometers and excite them to Rydberg states using lasers. The arrays are produced by a spatial light modulator, which shapes the dipole trap beam. We can create almost arbitrary geometries of the arrays. The talk will present our measurement of the van der Waals interaction between two individual atoms [Béguin, Phys. Rev. Lett. 110, 263201 (2013)], as well as the demonstration of the coherent energy exchange between two atoms resulting from their dipole-dipole interaction [Barredo, Phys. Rev. Lett. 114, 113002 (2015)]. |
