Summary• <strong>Quantum</strong> <strong>reflection</strong> shields nK BECs<strong>from</strong> a room temperature surface• Inter-atomic interactions strongly affectthe <strong>reflection</strong> dynamics• To avoid fragmentation uselow-density pancake-shaped BECs• Interfacing BECs with quantumelectronic devices <strong>of</strong>fer manypossibilities:– Re-writable, low-damage, lithography ?– Smooth, low-noise, near-surface trapsfor miniaturizing atom chipsFor details, see:PRL 100, 100402 (2008);New J.
