Abstract: An accelerometer-type interferometric ultracold atom inertial sensor including an atom chip including at least one set of a first and a second elementary sensor; an atom generation device; a generator for generating a uniform magnetic field; a power supply device; with the arrangement of the group of one or more conductive elements of each sensor and the sequence being further configured so that the trajectories associated with the first elementary sensor and the trajectories associated with the second elementary sensor are parallel to each other, are of the same length, are covered simultaneously and so that the departure direction of the first clouds, from the first and the second elementary sensor respectively, are opposite; the sensor further comprising a detection system.

Abstract: An interferometric inertial ultracold-atom sensor of gyrometer type, including an atom chip comprising at least one set of a first and second elementary sensor, a power-supplying device, the magnetic-field generator and the power-supplying device being configured to apply the magnetic field, the DC currents and the microwave signals in a predetermined sequence, the arrangement of the group of one or more conductive elements of each sensor and the sequence further being configured so that the path associated with the first elementary sensor and the path associated with the second elementary sensor are identical and traced simultaneously and in inverse directions by the clouds of ultracold atoms associated with a given internal state, the sensor further comprising a detecting system.

Abstract: An ultracold-atom sensor includes an atom chip (ACh) comprising a first and a second waveguide (CPWX1, CPWX2) that are suitable for propagating microwave waves and DC currents, at least a first conductive wire and a second conductive wire (WId, WId1) the respective projections of which are secant at a point defining a first crossing point (C1), an atom generation device (ACG), a power supply device (PSD) comprising at least one microwave generator (GMW) and at least one DC current generator (GDC), the power supply device being configured to apply, to the first and second waveguides and to spatially separate the two traps, the microwave signals in order to initiate the spatial separation, and then the CMW electric currents instead of the microwave signals in order to maintain the spatial separation.
