Theoretical Proposal of a Digital Closed-Loop Thermal Atomic-Beam Interferometer for High-Bandwidth, Wide-Dynamic-Range, and Simultaneous Absolute Acceleration-Rotation Sensing
Tomoya Sato, Toshiyuki Hosoya, Martin Miranda +3
We present a theoretical proposal and simulation study of a digital closed-loop thermal atomic-beam interferometer for inertial navigation applications. The scheme synchronizes pha…
Sensitivity Enhancement in Atom-Interferometer Gyroscopes via Phase-Modulation Signal Readout Scheme
Sotatsu Otabe, Naoki Kaku, Tomoya Sato +3
Quantum sensors based on atom interferometers are advancing both fundamental physics and practical applications, with higher sensitivity being a key requirement for these investiga…
Sub-Recoil Transverse Momentum Width in a Cold Ytterbium Atomic Beam
Toshiyuki Hosoya, Tomoya Sato, Ryotaro Inoue +1
We demonstrate the generation of a slow ytterbium atomic beam with a transverse momentum width of times the photon recoil associated with Bragg diffraction, and a flux of…
Closed-loop measurements in an atom interferometer gyroscope with velocity-dependent phase-dispersion compensation
Tomoya Sato, Naoki Nishimura, Naoki Kaku +4
Atom interferometer-based gyroscopes are expected to have a wide range of applications due to their high sensitivity. However, their dynamic range is limited by dephasing caused by…
Analyzing the sensitivity of an atom interferometer with a phase-modulation readout scheme
Takuya Kawasaki, Sotatsu Otabe, Tomoya Sato +3
The sensitivity of an interferometer depends on its readout scheme. However, little attention has been paid to the readout schemes of atom interferometers from the viewpoint of the…
