  • Continuous-Variable Square-Ladder Cluster States in a Microwave Frequency Comb

    Author(s): Fabio Lingua, J. C. Rivera Hernández, Michele Cortinovis, and David B. Haviland We describe an experiment demonstrating the generation of three independent square-ladder continuous-variable cluster states with up to 94 qumodes of a microwave frequency comb. This entanglement structure at a large scale is realized by injecting vacuum fluctuations into a Josephson Parametric Ampl… [Phys. Rev. Lett. 134, 183602] Published Fri May 09...

  • Cavity-Enhanced Solid-State Nuclear Spin Gyroscope

    Author(s): Hanfeng Wang, Shuang Wu, Kurt Jacobs, Yuqin Duan, Dirk R. Englund, and Matthew E. Trusheim A hybrid system composed of a nuclear spin in a nitrogen-vacancy center coupled to a cavity exhibits enhanced sensitivity at different operating regimes. [Phys. Rev. Lett. 134, 183603] Published Fri May 09, 2025

  • Detecting Phase Coherence of 2D Bose Gases via Noise Correlations

    Author(s): Shinichi Sunami, Vijay P. Singh, Erik Rydow, Abel Beregi, En Chang, Ludwig Mathey, and Christopher J. Foot We measure the noise correlations of two-dimensional (2D) Bose gases after free expansion and use them to characterize the in situ phase coherence across the Berezinskii-Kosterlitz-Thouless (BKT) transition. The noise correlation function features a characteristic spatial oscillatory behavior in the… [Phys. Rev. Lett. 134, 183407...

  • Detecting and Focusing on a Nonlinear Target in a Complex Medium

    Author(s): Antton Goïcoechea, Jakob Hüpfl, Stefan Rotter, François Sarrazin, and Matthieu Davy Wavefront shaping techniques allow waves to be focused on a diffraction-limited target deep inside disordered media. To identify the target position, a guidestar is required that typically emits a frequency-shifted signal. Here, we present a noninvasive matrix approach operating at a single frequenc… [Phys. Rev. Lett. 134, 183802] Published Thu May...

  • Thermodynamics of Spin-Imbalanced Fermi Gases with $\mathrm{S}\mathrm{U}(N)$-Symmetric Interaction

    Author(s): Chengdong He, Xin-Yuan Gao, Ka Kwan Pak, Yu-Jun Liu, Peng Ren, Mengbo Guo, Entong Zhao, Yangqian Yan, and Gyu-Boong Jo Thermodynamics of degenerate Fermi gases has been extensively studied through various aspects such as Pauli blocking effects, collective modes, BCS superfluidity, and more. Despite this, multicomponent fermions with imbalanced spin configurations remain largely unexplored, particularly beyond the tw… [Phys. Rev....

  • Time-Resolved Spectral Gap Spectroscopy in a Quantum Simulator of Fermionic Superfluidity inside an Optical Cavity

    Author(s): Dylan J. Young, Eric Yilun Song, Anjun Chu, Diego Barberena, Zhijing Niu, Vera M. Schäfer, Robert J. Lewis-Swan, Ana Maria Rey, and James K. Thompson We use an ensemble of laser-cooled strontium atoms in a high-finesse cavity to cleanly emulate the technique of rf spectroscopy employed in studies of BEC-BCS physics in fermionic superfluids of degenerate cold gases. Here, we leverage the multilevel internal structure of the atoms to...

  • Self-Organized Cavity Bosons beyond the Adiabatic Elimination Approximation

    Author(s): Giuliano Orso, Jakub Zakrzewski, and Piotr Deuar The longtime behavior of weakly interacting bosons moving in a two-dimensional optical lattice and coupled to a lossy cavity is investigated numerically via the truncated Wigner method, which allows us to take into full account the dynamics of the cavity mode, quantum fluctuations, cavity-boson corr… [Phys. Rev. Lett. 134, 183405] Published Tue May 06, 2025
