Fine-structure Raman interferometry with metastable barium for magnetically resilient inertial sensing
Masaki Nagamori, Hiromi Hatano, Toshiyuki Hosoya +3
Atom-interferometric quantum inertial sensors are promising candidates for inertial navigation systems owing to their high sensitivity and intrinsically low drift. However, their a…
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…
Observation of the Einstein-de Haas Effect in a Bose-Einstein condensate
Hiroki Matsui, Yuki Miyazawa, Ryoto Goto +4
The Einstein-de Haas effect is a phenomenon in which angular momentum is transferred from microscopic spins to mechanical rotation of a rigid body. Here, we report the first observ…
Simultaneous Suppression of Thermal Phase Noise and Relative Intensity Noise in a Fiber Optic Gyroscope
Nobuyuki Takei, Martin Miranda, Yuki Miyazawa +1
The short-term sensitivity of a kilometer-long fiber-optic gyroscope is limited mainly by thermal phase noise and relative intensity noise. Increasing the phase modulation frequenc…
Bose-Einstein Condensation of Europium
Yuki Miyazawa, Ryotaro Inoue, Hiroki Matsui +2
We report the realization of a Bose-Einstein condensate of europium atoms, which is a strongly dipolar species with unique properties, a highly symmetric $[\mathrm{Xe}]\ 4f^7 6s^2\…
Understanding one-body losses in magnetically trapped metastable europium atoms
Hiroki Matsui, Yuki Miyazawa, Ryotaro Inoue +1
We report the measurement of one-body loss rates for magnetically trapped metastable europium atoms and the study of their loss mechanism. The loss of atoms observed in a magneto-o…
Narrow-line magneto-optical trap for europium
Yuki Miyazawa, Ryotaro Inoue, Hiroki Matsui +2
We report on the realization of a magneto-optical trap (MOT) for europium atoms using a narrow-line cooling transition with a natural linewidth of 97 kHz. Our starting point is con…
Magneto-optical trapping of optically pumped metastable europium
Ryotaro Inoue, Yuki Miyazawa, Mikio Kozuma
We demonstrate laser cooling and magneto-optical trapping of europium. The atoms are optically pumped to a metastable state and then loaded from an atomic-beam source via conventio…
Measuring the branching ratios from the state to metastable states in europium
Yuki Miyazawa, Ryotaro Inoue, Keiji Nishida +2
We measure the branching ratios from the excited state to six metastable states of europium through fluorescence spectroscopy of an atomic beam. The sum of the s…
