An association sequence suitable for producing ground-state RbCs molecules in optical lattices
Arpita Das, Philip D. Gregory, Tetsu Takekoshi +5
We identify a route for the production of RbCs molecules in the rovibronic ground state that is compatible with efficient mixing of the atoms i…
Quantum Engineering of a Low-Entropy Gas of Heteronuclear Bosonic Molecules in an Optical Lattice
Lukas Reichsöllner, Andreas Schindewolf, Tetsu Takekoshi +2
We demonstrate a generally applicable technique for mixing two-species quantum degenerate bosonic samples in the presence of an optical lattice, and we employ it to produce low-ent…
Ultracold dense samples of dipolar RbCs molecules in the rovibrational and hyperfine ground state
Tetsu Takekoshi, Lukas Reichsöllner, Andreas Schindewolf +6
We produce ultracold dense trapped samples of 87Rb133Cs molecules in their rovibrational ground state, with full nuclear hyperfine state control, by stimulated Raman adiabatic pass…
Towards the production of ultracold ground-state RbCs molecules: Feshbach resonances, weakly bound states, and coupled-channel model
Tetsu Takekoshi, Markus Debatin, Raffael Rameshan +8
We have studied interspecies scattering in an ultracold mixture of Rb and Cs atoms, both in their lowest-energy spin states. The three-body loss signatures of 30 inc…
Molecular spectroscopy for ground-state transfer of ultracold RbCs molecules
Markus Debatin, Tetsu Takekoshi, Raffael Rameshan +7
We perform one- and two-photon high resolution spectroscopy on ultracold samples of RbCs Feshbach molecules with the aim to identify a suitable route for efficient ground-state tra…
Hyperfine, rotational and Zeeman structure of the lowest vibrational levels of the Rb $\tripletex$ state
T. Takekoshi, C. Strauss, F. Lang +3
We present the results of an experimental and theoretical study of the electronically excited $\tripletex$ state of Rb molecules. The vibrational energies are measured f…
