Author(s): Thomas K. Langin, Varun Jorapur, Yuqi Zhu, Qian Wang, and David DeMille We demonstrate loading of SrF molecules into an optical dipole trap (ODT) via in-trap $\mathrm{Λ}$-enhanced gray molasses cooling. We find that this cooling can be optimized by a proper choice of relative ODT and cooling beam polarizations. In this optimized configuration, we observe molecules with ... [Phys. Rev.

Author(s): Michał Lipka and Michał Parniak Single photons exhibit inherently quantum and unintuitive properties such as the Hong-Ou-Mandel effect, demonstrating their bosonic and quantized nature, yet at the same time may correspond to single excitations of spatial or temporal modes with a very complex structure. Those two features are rarel... [Phys. Rev. Lett. 127, 163601] Published Tue Oct 12, 2021

Author(s): Philipp Gersema, Kai K. Voges, Mara Meyer zum Alten Borgloh, Leon Koch, Torsten Hartmann, Alessandro Zenesini, Silke Ospelkaus, Junyu Lin, Junyu He, and Dajun Wang We probe photoinduced loss for chemically stable bosonic $^{23}\mathrm{Na}^{87}\mathrm{Rb}$ and $^{23}\mathrm{Na}^{39}\mathrm{K}$ molecules in chopped optical dipole traps, where the molecules spend a significant time in the dark. We expect the effective two-body decay to...

Author(s): Martín Drechsler, Sebastian Wolf, Christian T. Schmiegelow, and Ferdinand Schmidt-Kaler We demonstrate superresolution optical sensing of the size of the wave packet of a single trapped ion. Our method extends the well-known ground state depletion (GSD) technique to the coherent regime. Here, we use a hollow beam to strongly saturate a coherently driven dipole-forbidden transition arou... [Phys. Rev. Lett. 127, 143602] Published...

Author(s): Mikhail Mamaev, Peiru He, Thomas Bilitewski, Vijin Venu, Joseph H. Thywissen, and Ana Maria Rey We consider the nonequilibrium orbital dynamics of spin-polarized ultracold fermions in the first excited band of an optical lattice. A specific lattice depth and filling configuration is designed to allow the ${p}_{x}$ and ${p}_{y}$ excited orbital degrees of freedom to act as a pseudospin. Startin... [Phys. Rev.

Author(s): J. A. Haigh, A. Nunnenkamp, and A. J. Ramsay The polarization dependence of magnon-photon scattering in an optical microcavity is reported. Because of the short cavity length, the longitudinal mode-matching conditions found in previously explored, large path-length whispering gallery resonators are absent. Nonetheless, for cross-polarized scat... [Phys. Rev. Lett. 127, 143601] Published Tue Sep 28, 2021

Duan Trapped ions are one of the leading platforms in quantum information science. For quantum computing with large circuit depth and quantum simulation with long evolution time, it is of crucial importance to cool large ion crystals at runtime without affecting the internal states of the computational q... ...
