Trapping ultracold atoms at 100 nm from a chip surface in a 0.7-micrometer-period magnetic lattice

Yibo Wang, Tien Tran, Prince Surendran +6

We report the trapping of ultracold 87Rb atoms in a 0.7 micron-period 2D triangular magnetic lattice on an atom chip. The magnetic lattice is created by a lithographically patterne…
