ATOM INTERFEROMETER AND ATOMIC INTERFERENCE MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an atom interferometer of high sensitivity by a single mode atom waveguide solving a problem of loss of coherence caused by the interatomic collision.;SOLUTION: An atom waveguide 102 and an atom waveguide 103 constituted of wires of niobium (Nb) or the like are provided on a substrate 101 consisting of crystals of Al₂O₃ of sapphire or the like. The atom waveguide 102 and the atom waveguide 103 constitute a closed loop circuit by the superconductivity. The atom waveguide 102 and the atom waveguide 103 are provided close to each other while having areas facing each other. In the area in which the atom waveguide 102 and the atom waveguide 103 are opposite to each other, an atom trapping area 111 is arranged on one end side, an atom observing area 116 is arranged on the other end side, and an interference area is arranged therebetween.;COPYRIGHT: (C)2010,JPO&INPIT
