  • Information-Theoretic Bounds on Quantum Advantage in Machine Learning

    Author(s): Hsin-Yuan Huang, Richard Kueng, and John Preskill On average, classical and quantum machine learning techniques are comparable, but for accurate predictions on all inputs, there can be exponential quantum advantage. [Phys. Rev. Lett. 126, 190505] Published Fri May 14, 2021

  • Nuclear Spin Gyroscope based on the Nitrogen Vacancy Center in Diamond

    Author(s): Vladimir V. Soshenko, Stepan V. Bolshedvorskii, Olga Rubinas, Vadim N. Sorokin, Andrey N. Smolyaninov, Vadim V. Vorobyov, and Alexey V. Akimov A small device performs rotational measurements using nuclear spins in a diamond wafer, paving the way for microchip-sized gyroscopes. [Phys. Rev. Lett. 126, 197702] Published Fri May 14, 2021

  • Distinguishing a Mott Insulator from a Trivial Insulator with Atomic Adsorbates

    Author(s): Jinwon Lee, Kyung-Hwan Jin, and Han Woong Yeom A new experimental method based on adsorption can indicate whether a material is a Mott insulator or a common insulator. [Phys. Rev. Lett. 126, 196405] Published Thu May 13, 2021

  • Roton Excitations in an Oblate Dipolar Quantum Gas

    Author(s): J.-N. Schmidt, J. Hertkorn, M. Guo, F. Böttcher, M. Schmidt, K. S. H. Ng, S. D. Graham, T. Langen, M. Zwierlein, and T. Pfau Radial and angular roton excitations are observed in an oblate dipolar Bose-Einstein condensate around the phase transition to a 2D droplet crystal. [Phys. Rev. Lett. 126, 193002] Published Wed May 12, 2021

  • X-Ray Ptychography with a Laboratory Source

    Author(s): Darren J. Batey, Frederic Van Assche, Sander Vanheule, Matthieu N. Boone, Andrew J. Parnell, Oleksandr O. Mykhaylyk, Christoph Rau, and Silvia Cipiccia Researchers have scaled down x-ray ptychography—a high-resolution imaging technique that used to require large, expensive facilities—for use in the lab. [Phys. Rev. Lett. 126, 193902] Published Wed May 12, 2021

  • Self-Organized Multifrequency Clusters in an Oscillating Electrochemical System with Strong Nonlinear Coupling

    Author(s): Maximilian Patzauer and Katharina Krischer Self-organized multifrequency clusters in n-doped silicon wafers emerge from a uniform oscillatory state during electrodissolution at low-intensity photoexcitation. [Phys. Rev. Lett. 126, 194101] Published Mon May 10, 2021

  • Geometric Photon-Drag Effect and Nonlinear Shift Current in Centrosymmetric Crystals

    Author(s): Li-kun Shi, Dong Zhang, Kai Chang, and Justin C. W. Song The nonlinear shift current (associated with the bulk photovoltaic effect) in centrosymmetric crystals, known to be absent in crystals with inversion symmetry, could still be activated by a photon-drag effect.
