Design and Fabrication of Suspended Si₃N₄ Photonic Crystal Devices For Use With Cold Atoms

Finally, chapter 10 looks into simulations of a novel geometry of a dissipative atom ring trap that uses a hollow conical mirror combined with two pairs of anti-aligned anti-Helmholtz coils to realize an ”ARC” (Atoms Recycling Continuously) MOT where the potential minimum is to confine the circulating atomic beam along a ring. Similar to light circulating in a cavity, the atomic beam circulating in the ARC MOT could allow for a flux enhancement by a factor of 100. This could be a path to realizing a continuous high-cooperativity source of flux in a compact form.
