摘要

摘要

En 中文
We developed a new single-layer atom chip with an additional U-shaped current-carrying structure. The new U-shaped microwire creates optimized magnetic field distribution, which increases the trapping volume of a magneto-optical trap (MOT) near the chip. Our approach allows one to localize more atoms, while a setup remains relatively simple (single-layer approach) and consumes low current (up to 10 A). The total number of trapped 87 Rb atoms in our setup is 5 x 10 7 .
