A Proposal for Realizing an Array of Bose-Einstein Condensates

Yin Jian-Ping, Gao Wei-Jian, Jianjun Hu

We propose one-dimensional (1D) and two-dimensional (2D) arrays of magnetic surface microtraps for cold alkali atoms using some arrays of current-carrying wires and we calculate the spatial distributions of magnetic fields from the 1D and 2D arrays of current-carrying wires. The field gradients and curvatures from a single magnetic microtrap are analysed, and some interesting and periodic magnetic-well microstructures are found. The result shows that a magnetic-field gradient greater than 2.4 × 10 5 G/cm and a field curvature greater than 4.05 × 10 8 G/cm 2 can be generated in our array of magnetic microtraps, which can be used to realize the 1D and 2D arrays of Bose-Einstein condensations (or 1D and 2D arrays of Bose clusters) by rf-induced evaporative cooling, and then to form 1D and 2D atomic magnetic lattices, even to prepare 1D and 2D photonic crystals.

An atom chip is designed to manipulate magnetically trapped ultracold atoms and Bose-Einstein condensates (BECs) near a surface using micro fabricated patterns of current-carrying wires or permanent magnetic materials. We report on experiments using our permanent magnet atom chip.

A novel controllable double-layer magnetic lattice with cold atoms

恽旻, 印建平

We propose a novel array of controllable double-well magnetic microtraps for cold atoms by using an array of square current-carrying wires and two additional bias magnetic fields. Arrays of double layer magnetooptical traps (MOTs) and Ioffe traps can be constructed by using same wire configurations and different currents and bias fields. Furthermore, the array of double-well magnetic microtraps can be continuously evolved as an array of single-well magnetic microtraps by reducing the currents in the wires. Our study shows that our scheme can be used to realize a controllable double-layer magnetic lattice with cold atoms, to form array of Bose-Einstein condensations (BECs), or to study atom interference, and so on.
