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…
Metastable quantum phase transitions in a periodic one-dimensional Bose gas: II. Many-body theory
R. Kanamoto, L. D. Carr, M. Ueda
We show that quantum solitons in the Lieb-Liniger Hamiltonian are precisely the yrast states. We identify such solutions clearly with Lieb's type II excitations from weak to strong…
Metastable Quantum Phase Transitions in a Periodic One-dimensional Bose Gas: Mean-Field and Bogoliubov Analyses
R. Kanamoto, L. D. Carr, M. Ueda
We generalize the concept of quantum phase transitions, which is conventionally defined for a ground state and usually applied in the thermodynamic limit, to one for \emph{metastab…
Heteronuclear fermionic superfluids with spin degrees of freedom
D. B. M. Dickerscheid, Y. Kawaguchi, M. Ueda
We present a theory of spinor superfluidity in a two-species heteronuclear ultracold fermionic atomic gas consisting of arbitrary half-integer spin and one-half spin atoms. In part…
Vacuum Rabi oscillations in a macroscopic superconducting qubit LC oscillator system
J. Johansson, S. Saito, T. Meno +4
We have observed the coherent exchange of a single energy quantum between a flux qubit and a superconducting LC circuit acting as a quantum harmonic oscillator. The exchange of an…
