Revealing the velocity uncertainties of a levitated particle in the quantum ground state
M. Kamba, K. Aikawa
We demonstrate time-of-flight measurements for an ultracold levitated nanoparticle and reveal its velocity for the translational motion brought to the quantum ground state. We disc…
Recoil-limited feedback cooling of single nanoparticles near the ground state in an optical lattice
M. Kamba, H. Kiuchi, T. Yotsuya +1
We report on direct feedback cooling of single nanoparticles in an optical lattice to near their motional ground state. We find that the laser phase noise triggers severe heating o…
Electric feedback cooling of single charged nanoparticles in an optical trap
M. Iwasaki, T. Yotsuya, T. Naruki +3
We demonstrate feedback cooling of the center-of-mass motion of single charged nanoparticles to millikelvin temperatures in three dimensions via applying oscillating electric field…
Spontaneous continuous orbital motion of a pair of nanoparticles levitated in air
Mitsuyoshi Yoneda, Makoto Iwasaki, Kiyotaka Aikawa
We report on the discovery of a unidirectional continuous orbital motion of a single pair of nanoparticles which occurs spontaneously in room-temperature air and can be manipulated…
Anisotropic polarizability of erbium atoms
Jan Hendrik Becher, Simon Baier, Kiyotaka Aikawa +4
We report on the determination of the dynamical polarizability of ultracold erbium atoms in the ground and in one excited state at three different wavelengths, which are particular…
Thermal broadening of the power spectra of laser-trapped particles in vacuum
M. Yoneda, K. Aikawa
We show that at low pressures the spectral widths of the power spectra of laser-trapped particles are nearly independent from pressures and, due to the nonlinearities of the trap,…
