A combined system for generating a uniform magnetic field and its application in the investigation of Efimov physics

We propose a scheme to produce a uniform magnetic field with a system comprising a pair of coils and an atom chip. After optimizing the parameters of the chip wires, we improve the homogeneity of the magnetic field by two orders of magnitude. We exhibit that this method can be applied in the investigation of Efimov physics in ⁸⁷Rb-⁴⁰K mixture.
