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…

Characterization of charge-exchange collisions between ultracold atoms and ions
R. Saito, S. Haze, M. Sasakawa +5
We investigate the energy dependence and the internal-state dependence of the charge-exchange collision cross sections in a mixture of Li atoms and Ca ions in the co…
