“…we report an experimental observation of the out-of-equilibrium dynamics of a degenerate Fermi gas in the cavity after quenching the pump strength over a superradiant quantum phase transition…” Original paper: doi.org/10.1103/PhysRe…
“.. we demonstrate dipolar spin-exchange interactions between single calcium monofluoride (CaF) molecules trapped in an optical tweezer… we obtained a Bell state fidelity of 0.89(6)…” Original paper: science.org/doi/10.1126/sc…
“..Using the electric dipolar interaction between pairs of molecules prepared by using a reconfigurable optical tweezer array, we deterministically created Bell pairs of molecules..” Original paper: science.org/doi/10.1126/sc…
“.. Here, the quantum information is encoded in either of the three qubit manifolds and can be shuttled between them… we realize a nondestructive state detection for 171-Yb, incorporating global control and local feed-forward operations..” Paper: doi.org/10.1103/PhysRe…
“.. This work establishes a clear methodology for designing and verifying error-robust control solutions for atom interferometers, and opens a novel pathway towards ruggedized cold-atom sensors for deployment in real-world environments…” Original paper: doi.org/10.1038/s41467…
“..we report…the first simultaneous production of a dual-species BEC in space… We have further achieved the first spaceborne demonstration of simultaneous atom interferometry with two atomic species…” Original paper: doi.org/10.1038/s41586…
“… we have demonstrated single-atom trapping and high-fidelity imaging of Dy on the intercombination line in tweezers rendered magic by fine tuning the tweezer polarization…” Original paper: doi.org/10.1103/PhysRe…
“…Our results confirm two predictions of Landau’s Fermi-liquid theory: the shift in polaron energy due to mediated interactions, which is linear in the concentration of impurities; and its sign inversion with impurity quantum statistics…” Nature Physics: doi.org/10.1038/s41567…
Job Alert! I am hiring a PDRA to work on a new K-Rb quantum-mixture experiment exploring vortex dynamics in binary superfluids @EQOP @PhysicsStrath. See bit.ly/QuantumFluidsP… or contact me @drlabgnome for more details. Please share!
The @OxfordPhysics & @unihh team published in @ScienceMagazine. We quench 2D Bose gases across the BKT transition and probe the relaxation dynamics with matter-wave interferometry; we found that the scaling behaviour is consistent with real-time RG theory. science.org/doi/10.1126/sc…
