Measurement of the variation of electron-to-proton mass ratio using ultracold molecules produced from laser-cooled atoms
Jun Kobayashi, Atsushi Ogino, Shin Inouye
Experimental techniques to manipulate cold molecules have seen great development in recent years. The precision measurements of cold molecules are expected to give insights into fu…
Antiferromagnetic Interorbital Spin-Exchange Interaction of Yb
Koki Ono, Jun Kobayashi, Yoshiki Amano +2
We report on the investigation of the scattering properties between the ground state and the metastable state of the fermionic isotope of Yb. We successfull…
Experimental Determination of Bose-Hubbard Energies
Yusuke Nakamura, Yosuke Takasu, Jun Kobayashi +5
We present the first experimental measurement of the ensemble averages of both the kinetic and interaction energies of the three-dimensional Bose--Hubbard model at finite temperatu…
Isotopic shift of atom-dimer Efimov resonances in K-Rb mixtures: Critical effect of multichannel Feshbach physics
K. Kato, Yujun Wang, J. Kobayashi +2
The multichannel Efimov physics is investigated in ultracold heteronuclear admixtures of K and Rb atoms. We observe a shift in the scattering length where the first atom-dimer reso…
Site-resolved imaging of single atoms with a Faraday quantum gas microscope
Ryuta Yamamoto, Jun Kobayashi, Kohei Kato +3
We successfully demonstrate a quantum gas microscopy using the Faraday effect which has an inherently non-destructive nature. The observed Faraday rotation angle reaches 3.0(2) deg…
An ytterbium quantum gas microscope with narrow-line laser cooling
Ryuta Yamamoto, Jun Kobayashi, Takuma Kuno +2
We demonstrate site-resolved imaging of individual bosonic atoms in a Hubbard-regime two-dimensional optical lattice with a short lattice constant of 266 nm. To…
