Author(s): Alejandra L. Collopy, Julian Schmidt, Dietrich Leibfried, David R. Leibrandt, and Chin-Wen Chou We characterize and model the Stark effect due to the radio-frequency (rf) electric field experienced by a molecular ion in an rf Paul trap, a leading systematic in the uncertainty of the field-free rotational transition. The ion is deliberately displaced to sample different known rf electric fields… [Phys. Rev. Lett. 130, 223201] Published...

Author(s): Daniel K. Ruttley, Alexander Guttridge, Stefan Spence, Robert C. Bird, C. Ruth Le Sueur, Jeremy M. Hutson, and Simon L. Cornish By merging two optical tweezers containing a single atom each, an ultracold molecule is formed in the motional ground state. [Phys. Rev. Lett. 130, 223401] Published Wed May 31, 2023

Author(s): Sofus Laguna Kristensen, Eliot Bohr, Julian Robinson-Tait, Tanya Zelevinsky, Jan W. Thomsen, and Jörg Helge Müller Superradiant lasers operate in the bad-cavity regime, where the phase coherence is stored in the spin state of an atomic medium rather than in the intracavity electric field. Such lasers use collective effects to sustain lasing and could potentially reach considerably lower linewidths than a convent… [Phys. Rev. Lett...

Author(s): V. A. Pammi, M. G. Clerc, S. Coulibaly, and S. Barbay The forecasting of high-dimensional, spatiotemporal nonlinear systems has made tremendous progress with the advent of model-free machine learning techniques. However, in real systems it is not always possible to have all the information needed; only partial information is available for learning and … [Phys. Rev.

Author(s): Leizhen Chen, Liangliang Lu, Lijun Xia, Yanqing Lu, Shining Zhu, and Xiao-song Ma Integrated quantum photonics has recently emerged as a powerful platform for generating, manipulating, and detecting entangled photons. Multipartite entangled states lie at the heart of the quantum physics and are the key enabling resources for scalable quantum information processing. Dicke state is… [Phys. Rev.

Connecting photonic topological states with far-field degrees of freedom (d.o.f.) has given rise to fruitful phenomena. Recently...

Author(s): B. D. Hauer, J. Combes, and J. D. Teufel The ability to prepare a macroscopic mechanical resonator into a quantum superposition state is an outstanding goal of cavity optomechanics. Here, we propose a technique to generate cat states of motion using the intrinsic nonlinearity of a dispersive optomechanical interaction. By applying a bichro… [Phys. Rev.
