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…
Prospects for Narrow-line Cooling of KRb Molecules in Rovibrational Ground State
J. Kobayashi, K. Aikawa, K. Oasa +1
We propose and experimentally investigate a scheme for narrow-line cooling of KRb molecules in the rovibrational ground state. We show that the spin-forbidden $\mathrm{X^1Σ^+} \rig…
Predicting and verifying transition strengths from weakly bound molecules
K. Aikawa, D. Akamatsu, M. Hayashi +3
We investigated transition strengths from ultracold weakly bound 41K87Rb molecules produced via the photoassociation of laser-cooled atoms. An accurate potential energy curve of th…
Coherent transfer of photoassociated molecules into the rovibrational ground state
K. Aikawa, D. Akamatsu, M. Hayashi +6
We report on the direct conversion of laser-cooled 41K and 87Rb atoms into ultracold 41K87Rb molecules in the rovibrational ground state via photoassociation followed by stimulated…
Direct evaporative cooling of 41K into a Bose-Einstein condensate
T. Kishimoto, J. Kobayashi, K. Noda +3
We have investigated the collisional properties of 41K atoms at ultracold temperature. To show the possibility to use 41K as a coolant, a Bose-Einstein condensate of 41K atoms in t…
Cross-Dimensional relaxation in Bose-Fermi mixtures
J. Goldwin, S. Inouye, M. L. Olsen +1
We consider the equilibration rate for fermions in Bose-Fermi mixtures undergoing cross-dimensional rethermalization. Classical Monte Carlo simulations of the relaxation process ar…
