Abstract: An atom chip (Ach) for an ultra-cold atom sensor, the atom chip includes a first pair of waveguides, a second pair of waveguides, the projections of the guides along X and the guides along Y′ in the plane XY forming, at their intersection, a first parallelogram with a centre O and having a first surface, a first conductive strip and a second conductive strip arranged such that their respective projection in the plane XY forms, at their intersection, a second parallelogram also with a centre O and having a second surface, the strips being designed to be flowed through by DC currents, an intersection between the first and the second surface being greater than or equal to 40% of the first surface.

Abstract: An atom chip (Ach) for an ultra-cold atom sensor, includes a measurement plane XY of the atom chip comprising: a plurality of first pairs of waveguides, a plurality of second pairs of waveguides, the projections in the plane XY of the first pair furthest from X and of the second pair furthest from Y′ forming, at their intersection, a parallelogram with a centre O, a first conductive wire having a projection in the plane XY along X or Y′ or a diagonal of the parallelogram, the first conductive wire being designed to be flowed through by a DC current, the first wire having a flaring so as to take the form of a surface whose projection in the plane XY incorporates the parallelogram and exhibits symmetry about the point O.
