Phys. Rev. Applied 26, 034003 (2026) - Published 1 September, 2026

Atomic interferometers offer extraordinary inertial sensitivity, yet their intrinsically periodic response has long prevented continuous operation over a wide dynamic range. The authors demonstrate a dual-channel closed-loop atomic beam interferometer, enabling simultaneous quantum feedback for rotation and acceleration. By converting periodic matter-wave interference into continuously tracked control parameters, the scheme overcomes the conventional half-fringe limitation while preserving precision. This advance brings practical quantum inertial navigation a significant step closer.

Direct observation of photon-induced vortices in superconducting films

Takeshi Jodoi, Fuminori Hirayama, Tetsuya Tsuruta, Takahiro Kikuchi, and Daiji Fukuda

Phys. Rev. Applied 26, 034005 (2026) - Published 2 September, 2026

What happens when a photon is absorbed by a superconductor? Although vortex-antivortex pairs have long been suspected to play a central role in superconducting photon detection, their dynamics following photon absorption have eluded direct observation. By monitoring quantized voltage signals generated by photon-induced vortices, the authors reveal their generation statistics and demonstrate photon-number resolution. This work provides a rare microscopic view of photon detection in superconductors, and opens a route toward fast superconducting photon-number-resolving detectors.

Perturbative sensing of nanoscale quantum materials with millimeter-wave photonic crystals

Kevin K. S. Multani, Zhurun Ji, Wentao Jiang, Siyuan Qiu, Akasha G. Hayden, Gitanjali Multani, Sharon R. Platt, Emilio A. Nanni, Zhi-Xun Shen, and Amir H. Safavi-Naeini

Phys. Rev. Applied 26, L031001 (2026) - Published 1 September, 2026

Millimeter waves sit at the energy scale of many collective excitations in quantum materials, but probing microscopic samples at these frequencies is difficult: Spectroscopic alignment is hard in a cryostat, and superconducting cavities stop working in high magnetic fields. This Letter reports an all-silicon (no metal or superconductor) photonic crystal cavity functioning as a chip-scale conductivity sensor near 100 GHz, reaching a quality factor above $10^{5}$ at 4.3 K. The all-dielectric platform should work at the strong fields and low temperatures where quantum Hall edge modes, magnetoplasmons, and field-tuned correlated phases exist, and it may be scalable to terahertz frequencies.

Enhancement of magnon-phonon coupling in ferromagnetic ${Co}_{2} FeSi$ alloy using the monostable-bistable magnetic transition

Kazuto Yamanoi, Shinya Yamada, Kohei Hamaya, and Yukio Nozaki

Phys. Rev. Applied 26, L031002 (2026) - Published 2 September, 2026

Magnon-phonon hybridization enables coupled control of spin and mechanical excitations, but the limited frequency tunability of conventional surface-acoustic-wave (SAW) devices is restrictive. The authors develop a SAW platform with a fundamental frequency of 193 MHz, enabling quasicontinuous mapping of magnon-phonon resonances up to 5.6 GHz in an epitaxial Co $_{2}$ FeSi film. Magnon-induced SAW absorption is enhanced near the transition between monostable and bistable magnetization states; even so, the two regimes exhibit distinct frequency scalings. This approach provides a route toward tunable, potentially energy-efficient magnonic devices and dynamic spin control in hybrid systems.

Collimated light emission from inelastic electron tunneling enabled by a nonlocal plasmonic metasurface

Yu Wu, Dudu Song, Zhengyi Lu, Shunping Zhang, and Hongxing Xu

Phys. Rev. Applied 26, L031003 (2026) - Published 3 September, 2026

Light emission via inelastic electron tunneling (LEIT) is an ultrabroadband light source with potential impact in visible-light communication, intelligent optical sensing, and on-chip optoelectronics. Its low efficiency is typically addressed using plasmonic tunneling junctions, but their subwavelength size results in omnidirectional radiation with poor collimation. The authors combine a plasmonic tunneling junction with a metasurface to collimate LEIT to a narrow divergence angle across a broad spectral window. The supported hybrid plasmon-photon modes both enhance the local density of states and extend spatial coherence, mitigating the trade-off between response speed and collimation.

Toward high-resolution low-energy electron spectroscopy with transition-edge sensors

R. Ammendola et al. (PTOLEMY Collaboration)

Phys. Rev. Applied 26, L031004 (2026) - Published 9 September, 2026

Transition-edge sensors (TESs) have already been proven to detect electrons with kinetic energy of about 100 eV, with a Gaussian energy resolution of 1 eV, comparable to the photon energy resolution of the same device. This study investigates how changes in the experimental setup influence the energy resolution of TES devices, for electrons produced by a ‘cold’ source of vertically aligned carbon nanotubes. Decreasing the size of both TES and electron source, the energy resolution for electrons significantly improves by a factor of more than 21. These results open up possibilities for the high-resolution spectroscopy of low-energy electrons, for e.g. the measurement of neutrino mass.

High-fidelity transmon reset with a multimode acoustic resonator

Andraž Omahen, Simon Storz, Igor Kladarić, and Yiwen Chu

Phys. Rev. Applied 26, L031005 (2026) - Published 16 September, 2026

Superconducting qubits must be initialized in their ground state with very high fidelity, for quantum computing and sensing. Conventional reset schemes are limited, as they operate the qubit within the same noisy electromagnetic environment used for its everyday control. This study couples a transmon qubit to a high-overtone bulk acoustic resonator, a physically distinct bath that is intrinsically colder than its electromagnetic surroundings. The authors use its multimode structure to repeatedly extract entropy from the qubit. This simple, feedback-free protocol yields residual excited-state populations one to two orders of magnitude lower than for typical schemes.
