Time-of-flight force sensing below the quantum zero-point fluctuation
Sotatsu Otabe, Mitsuyoshi Kamba, Yuto Kojima +1
Sensing weak forces through observing a mechanical motion near or below its quantum zero-point fluctuation has been desired in diverse areas. While mechanical oscillators have play…
Quantum squeezing of a levitated nanomechanical oscillator
M. Kamba, N. Hara, K. Aikawa
Manipulating the motions of macroscopic objects near their quantum mechanical uncertainties has been desired in diverse fields, including fundamental physics, sensing, and transduc…
Nanoscale feedback control of six degrees of freedom of a near-sphere
M. Kamba, R. Shimizu, K. Aikawa
We demonstrate feedback cooling of all the angular motions of a near-spherical neutral nanoparticle with all the translational motions feedback-cooled to near the ground state. The…
Optical cold damping of neutral nanoparticles near the ground state in an optical lattice
Mitsuyoshi Kamba, Ryoga Shimizu, Kiyotaka Aikawa
We propose and demonstrate purely optical feedback cooling of neutral nanoparticles in an optical lattice to an occupation number of . The cooling force is derived fro…
