A point source interferometer (PSI) is a device where atoms are split and recombined by applying temporal sequence of Raman pulses during the expansion cloud cold behaving approximately as source. The PSI can work sensitive multi-axes gyroscope that automatically filter out signal from accelerations. phase shift arising rotations proportional to momentum transferred each atom pulses. Therefore,...

We report the observation of superfluid quantum interference in a compact, large-area matter-wave interferometer consisting of a multiple-turn interfering path in reciprocal geometry. Utilizing the Sagnac effect from Earth's rotation in conjunction with a phase shifter made of superfluid heat current, we demonstrate that such a scheme can be extended for sensitive rotation sensing as well as fo...
