Measurement of ion displacement via RF power variation for excess micromotion compensation
Ryoichi Saito, Kota Saito, Takashi Mukaiyama
We demonstrate a method of micromotion minimization of a trapped ion in a linear Paul trap based on the precision measurement of the ion trapping position displacement due to a str…
Three-dimensional matter-wave interferometry of a trapped single ion
Ami Shinjo, Masato Baba, Koya Higashiyama +2
We report on a demonstration of Ramsey interferometry by three-dimensional motion with a trapped ion. We applied a momentum kick to the ion in a direction diagonal to…
Cooling dynamics of a single trapped ion via elastic collisions with small-mass atoms
Shinsuke Haze, Mizuki Sasakawa, Ryoichi Saito +2
We demonstrated sympathetic cooling of a single ion in a buffer gas of ultracold atoms with small mass. Efficient collisional cooling was realized by suppressing collision-induced…
A self-injected, diode-pumped, solid-state ring laser for laser cooling of Li atoms
Yudai Miake, Takashi Mukaiyama, Kenneth M. O'Hara +1
We have constructed a solid-state light source for experiments with laser cooled lithium atoms based on a Nd:YVO ring laser with second-harmonic generation. Unidirectional lasi…
Charge-exchange collisions between ultracold fermionic lithium atoms and calcium ions
Shinsuke Haze, Ryoichi Saito, Munekazu Fujinaga +1
Charge exchange collisions between ultracold fermionic 6Li atoms and 40Ca+ ions are observed in the mK temperature range. The reaction product of the charge exchange collision is i…
Experimental Determination of p-wave Scattering Parameters in ultracold 6Li atoms
Takuya Nakasuji, Jun Yoshida, Takashi Mukaiyama
We report the experimental determination of the scattering parameters for a p-wave Feshbach resonance in a single component Fermi gas of 6Li atoms in the lowest spin state. The tim…
Observation of elastic collisions between lithium atoms and calcium ions
Shinsuke Haze, Sousuke Hata, Munekazu Fujinaga +1
We observed elastic collisions between laser-cooled fermionic lithium atoms and calcium ions at the energy range from 100 mK to 3 K. Lithium atoms in an optical-dipole trap were tr…
