    "abstract": "A new geometry of optical lattice is proposed, namely a lattice made of a 1D\nstack of ring traps. It is obtained though the interference pattern of two\ncounterpropagating beams: one of the beam is a standard gaussian beam, while\nthe other one is a hollow beam obtained through a setup with two conical\nlenses. The resulting lattice is shown to have a high filling rate and a good\nconfinement, so that it could be loaded directly from a MOT with applications\nin the domain of quantum computing, or with a Bose-Einstein condensate, which\nwould have in this case a 1D ring geometry.",
