Rev. Applied 20, 054061 (2023) – Published 30 November 2023 Synopsis:Mapping the Thermal Forces That Push Particles through Liquids Using fluorescent tracers, researchers visualize the forces that move micrometer-diameter particles through a liquid subjected to a temperature gradient.     Editors' Suggestion Piezo-orbital backaction force in a rare-earth-doped crystal A. Louchet-Chauvet, P. Verlot, J.-P. Poizat, and T. Chanelière Phys. Rev. Applied 20, 054004 (2023) – Published 1 November 2023 Hybrid optomechanics can bridge the quantum and classical domains, to generally extend quantum principles to macroscopic scale. A milestone here would be observing the fundamental backaction force that occurs when a hybrid mechanical system is optically probed, which can be dominated by classical thermal effects. Using a large ensemble of rare-earth ions in a crystal plus time-resolved tomography, researchers see this backaction as a tiny distortion of the crystal's surface around a laser beam's spot, and unambiguously distinguish the photothermal contribution from that of the backaction. Thus rare-earth ions in crystals are confirmed as a promising platform for hybrid optomechanics.     Editors' Suggestion Cryogenic spin Peltier effect detected by a RuO2−AlOx on-chip microthermometer Takashi Kikkawa, Haruka Kiguchi, Alexey A. Kaverzin, Ryo Takahashi, and Eiji Saitoh Phys. Rev. Applied 20, 054006 (2023) – Published 2 November 2023 Exploring low-temperature thermometry, particularly at the micro- to nanoscale, is essential not only for advancing thermoelectric science, but also for the development of quantum technology. The authors present a methodology and an experimental platform based on an on-chip microthermometer, enabling the detection of extremely small temperature changes in thin films, down to tens of nanokelvins. Using this approach, the authors observe the spin Peltier effect (temperature modulation induced by spin current) at 2 K. Their methods have the potential to uncover other low-temperature thermoelectric effects in microdevices, including those made of two-dimensional van der Waals materials.     Editors' Suggestion Measurement-induced state transitions in a superconducting qubit: Within the rotating-wave approximation Mostafa Khezri, Alex Opremcak, Zijun Chen, Kevin C. Miao, Matt McEwen, Andreas Bengtsson, Theodore White, Ofer Naaman, Daniel Sank, Alexander N. Korotkov, Yu Chen, and Vadim Smelyanskiy Phys. Rev. Applied 20, 054008 (2023) – Published 3 November 2023 Fast nondemolition measurement of superconducting qubits is important for the operation of quantum computers, but readout is constrained by measurement-induced state transitions that shift the qubit population outside of its computational subspace. This work experimentally characterizes the phenomenon and provides an intuitive model to explain its physical process. Surprisingly, the offset charge of the transmon qubit, which is usually ignored, is important in explaining the experiments. These results inform engineering and physics-based solutions to this problem by providing performance limits for the dispersive readout of superconducting qubits.     Editors' Suggestion Deep-learning-based radio-frequency side-channel attack on quantum key distribution Adomas Baliuka, Markus Stöcker, Michael Auer, Peter Freiwang, Harald Weinfurter, and Lukas Knips Phys. Rev. Applied 20, 054040 (2023) – Published 20 November 2023 Quantum key distribution (QKD) is a technique that allows two distant parties to distribute and share a common secret, which then can be used as a cryptographic key. While mathematical proofs verify the security of perfectly implemented systems, imperfections in real devices allow attackers to retrieve information. This study uses machine-learning techniques to investigate information leakage via radio-frequency emissions of QKD device electronics. The approach allows researchers and engineers to harden devices against attacks.     Editors' Suggestion High-resolution acoustic field mapping of gigahertz phononic crystals with atomic force microscopy Alessandro Pitanti, Mingyun Yuan, Simone Zanotto, and Paulo Ventura Santos Phys. Rev. Applied 20, 054054 (2023) – Published 27 November 2023 Manipulating mechanical waves at gigahertz frequencies can lead to next-generation communication technologies, but designing wave-controlling devices requires high-resolution and fast-scanning mapping of acoustic fields. The authors introduce the use of acoustic atomic force microscopy to characterize phononic crystals at gigahertz frequency, showing mechanical vibration mapping with tens-of-nanometer resolution and symmetry-dependent scattering. This study sets the baseline for advanced operations like hyperspectral filtering, beam steering, or spatial-division multiplexing, and will have an impact on the development of acoustic-based microwave technologies.     Editors' Suggestion Single-spin spectroscopy of spontaneous and phase-locked spin-torque-oscillator dynamics Adrian Solyom, Michael Caouette-Mansour, Brandon Ruffolo, Patrick Braganca, Lilian Childress, and Jack C. Sankey Phys. Rev. Applied 20, 054055 (2023) – Published 28 November 2023 Nanoscale magnetic circuits provide an alternate paradigm for computation and signal processing, but characterizing the GHz-frequency magnetic dynamics in these systems has been challenging. The authors use the single spin of a nitrogen-vacancy (N-V) center in diamond to probe nanoscale magnetic fields in the GHz regime, identifying signatures of a free-running and phase-locked spin-torque oscillator in the fluorescence spectrum of a proximal N-V, and measure how the dynamics impact the N-V's spin relaxation. This technique could enable new sensing modalities for revealing the nanoscale structure of GHz-frequency dynamics in emerging magnetic nanotechnologies.     Editors' Suggestion Propagating-spin-wave spectroscopy using inductive antennas: Conditions for unidirectional energy flow Thibaut Devolder Phys. Rev. Applied 20, 054057 (2023) – Published 28 November 2023 Spin waves are of central importance in spintronic as they determine the rate at which the magnetization can vary. They can be better studied by using propagating-spin-wave spectroscopy with a physically transparent model. This study of spin-wave transduction focuses on the interaction between spin waves and microwaves, and the impact of the spin-wave dispersion relation. The authors choose specific magnetization orientations so that the magnons and microwave photons do not couple, and show that line-shaped dispersion relations can be harnessed to engineer reconfigurable, nonreciprocal frequency filters transferring spin wave energy in a unidirectional manner.     PERSPECTIVES Perspective Polarization transport in ferroelectrics G.E.W. Bauer, P. Tang, R. Iguchi, J. Xiao, K. Shen, Z. Zhong, T. Yu, S.M. Rezende, J.P. Heremans, and K. Uchida Phys. Rev. Applied 20, 050501 (2023) – Published 29 November 2023 In analogy to the subfield of magnonics in magnetism, ferronics is the study of the elementary excitations of ferroelectric order, termed ferrons. From this basis the authors offer their perspective on our present understanding of electric polarization currents in ferroelectric materials, and potential applications in thermal management and information technologies.     LETTERS Letter Topological nature of non-Hermitian degenerate bands in structural parameter space Olivia Y. Long, Cheng Guo, and Shanhui Fan Phys. Rev. Applied 20, L051001 (2023) – Published 30 November 2023 Band degeneracies at high-symmetry points in wavevector space have been shown to exhibit rich physical phenomena in photonics, but obtaining degenerate bands away from such points is highly nontrivial. This work demonstrates complex band degeneracy in a photonic crystal structure over a region of momentum space. The authors show that this band degeneracy corresponds to polarization-independent transmission and manifests as a topological singularity in the structural parameter space of the system. Such degeneracy can be harnessed for the design of nonlocal polarization-independent photonic structures.     ARTICLES Frequency-mixing spectroscopy of spins in diamond Mohammed Attrash, Sergei Masis, Sergey Hazanov, Oleg Shtempluck, and Eyal Buks Phys.
