Rev. Applied 18, 064001 (2022) – Published 1 December 2022 Shallow impurities play critical roles in the applications of semiconductor materials, but their simulations through first-principles calculations are challenging due to the delocalized nature of the impurity wave function. The authors propose a first-principles approach to study shallow impurities, which allows simulations of extremely large supercells to obtain converged impurity levels and wave functions. The method is applied to acceptor-carbon complexes in silicon and yields good agreement with experiments. This work thus presents a feasible approach for accurate simulations of shallow impurities and can provide helpful insights to assist experimental dopant engineering.     Editors' Suggestion Triplet-Polaron-Annihilation-Induced Degradation of Organic Light-Emitting Diodes Based on Thermally Activated Delayed Fluorescence Bas van der Zee, Yungui Li, Gert-Jan A.H. Wetzelaer, and Paul W.M. Blom Phys. Rev. Applied 18, 064002 (2022) – Published 1 December 2022 Organic light-emitting diodes (OLEDs) based on thermally activated delayed fluorescence (TADF) are alternatives to today's commercial phosphorescent OLEDs with heavy-metal dopants, but their limited stability remains a key issue. This work provides a quantitative insight into the degradation mechanisms. The authors reproduce the voltage and light output using a recently developed device model, and find that triplet-polaron annihilation is the driving force behind the formation of degradation traps. This understanding leads to the experimental demonstration of enhanced device lifetime, and will provide guidance towards improved stability of TADF OLEDs.     Editors' Suggestion Coherence Properties of Electron-Beam-Activated Emitters in Hexagonal Boron Nitride Under Resonant Excitation Jake Horder, Simon J.U. White, Angus Gale, Chi Li, Kenji Watanabe, Takashi Taniguchi, Mehran Kianinia, Igor Aharonovich, and Milos Toth Phys. Rev. Applied 18, 064021 (2022) – Published 8 December 2022 Lattice defects in two-dimensional materials are compelling sources of single photons for applications in quantum information processing. However, the range of emission wavelengths is broad, the defect types vary and the atomic structures of most are unknown, and the inability to fabricate defects systematically on demand has limited progress. This work leverages a robust, site-specific fabrication technique to produce arrays of blue quantum emitters for study via cryogenic spectroscopy. The authors characterize processes that limit emitter coherence and observe Rabi oscillations, demonstrating the potential of these defects for scalable quantum technologies.     Editors' Suggestion Autonomous Estimation of High-Dimensional Coulomb Diamonds from Sparse Measurements Anasua Chatterjee, Fabio Ansaloni, Torbjørn Rasmussen, Bertram Brovang, Federico Fedele, Heorhii Bohuslavskyi, Oswin Krause, and Ferdinand Kuemmeth Phys. Rev. Applied 18, 064040 (2022) – Published 14 December 2022 In spin-based quantum processors, each quantum dot of a qubit is populated by exactly one electron, which requires careful tuning of each gate voltage such that it lies inside the charge-stability region (the "Coulomb diamond") associated with the dot array. However, mapping the boundary of a multidimensional Coulomb diamond by traditional dense raster scanning would take years, so the authors develop a sparse acquisition technique that autonomously learns Coulomb-diamond boundaries from a small number of measurements. Here we have hardware-triggered line searches in the gate-voltage space of a silicon quadruple dot, with smart search directions proposed by an active-learning algorithm.     Editors' Suggestion Improved Coherent One-Way Quantum key Distribution for High-Loss Channels Emilien Lavie and Charles C.-W. Lim Phys. Rev. Applied 18, 064053 (2022) – Published 19 December 2022 Coherent one-way quantum key distribution (COW-QKD) is a popular cryptography protocol, due to its fairly simple implementation and passive measurement device. Its security analysis is challenging, though, and extra assumptions or modifications are typically employed. Here the authors propose minor modifications to COW-QKD's prepared states while retaining the original, fully passive measurement device, and generalize the "universal squashing" framework to analyze their system's security. The results suggest that performance should be comparable to upper bounds from the literature, making this protocol a viable alternative to one based on phase-modulated coherent states.     Editors' Suggestion Untrained Physically Informed Neural Network for Image Reconstruction of Magnetic Field Sources A.E.E. Dubois, D.A. Broadway, A. Stark, M.A. Tschudin, A.J. Healey, S.D. Huber, J.-P. Tetienne, E. Greplova, and P. Maletinsky Phys. Rev. Applied 18, 064076 (2022) – Published 26 December 2022 Magnetic materials are a vital resource in designing energy-efficient information technologies. To try to learn how magnetism develops in ultrathin systems, we measure, but deducing the physics afterward is an ill-posed problem. This study uses neural networks to facilitate the reconstruction of the underlying magnetic textures of thin magnets through measurements of their stray fields. The technique is surprisingly robust to experimental noise, and can reliably reconstruct magnetism in arbitrary directions. Importantly, prior training of the network is not required, and the technique is broadly applicable for solving ill-posed inverse problems when the forward problem is well defined.     Editors' Suggestion Flows in Straws: Viscous Flows in One-Dimensional Metamaterial Peter Breitman, Michael Pukshansky, Anna Zigelman, Ezra Ben Abu, Ofek Peretz, Sefi Givli, and Amir D. Gat Phys. Rev. Applied 18, 064077 (2022) – Published 26 December 2022 The authors study the interaction between a viscous flow and a one-dimensional mechanical metamaterial composed of bistable unit cells, much like a drinking straw. Their twofold model shows excellent agreement with experimental results. While prior studies have focused on tailoring unit-cell structure to obtain a desired multistable behavior, here the viscous fluid allows tuning of rate-dependent properties and nonlocal interaction between unit cells. The ability to manipulate both structural and nonlocal rate-related properties points to the development of smart materials with tunable kinetic relations, large reversible deformations, and tailored dynamic properties.     Editors' Suggestion Fracturing in Wet Granular Media Illuminated by Photoporomechanics Yue Meng, Wei Li, and Ruben Juanes Phys. Rev. Applied 18, 064081 (2022) – Published 27 December 2022 Unraveling the complex behavior of wet granular media has been challenging, because the effective stresses transmitted through the particles have remained unobservable. The authors use their recently developed extension of photoelasticity for coupled fluid-granular systems to image particle stresses during fracture by air injection in an oil-saturated granular pack. They discover two states of the granular medium evolving with the fractures, plus an "effective-stress shadow" behind the propagating fracture tips. This study points out the power of photoporomechanics for studying coupled fluid-solid processes in granular media, including energy recovery, gas venting, and geohazards.     Editors' Suggestion Strong Kinetic-Inductance Kerr Nonlinearity with Titanium Nitride Nanowires Chaitali Joshi, Wenyuan Chen, Henry G. LeDuc, Peter K. Day, and Mohammad Mirhosseini Phys. Rev. Applied 18, 064088 (2022) – Published 28 December 2022 The kinetic inductance of charge carriers in disordered superconductors provides a broadband low-loss source of nonlinear electromagnetic response. This work investigates TiN nanowires as an alternative to Josephson junctions for applications involving elevated temperatures, higher frequencies, and strong magnetic fields. An extreme nanowire geometry for TiN microwave resonators leads to current-density concentration and enhanced self-Kerr coefficient, yielding a nonlinearity-to-loss ratio as high as 21% and quality factor exceeding 10,000. Such devices may find application in quantum frequency conversion of microwave photons, and with improvement might attain strong quantum nonlinearity.     Editors' Suggestion Letter Magnetic Imaging with Spin Defects in Hexagonal Boron Nitride P.

Applied 18, L061002 (2022) – Published 21 December 2022 This work bridges research on two-dimensional (2D) materials and quantum sensing technology by demonstrating that optically active spin defects in hexagonal boron nitride can be used for quantitative magnetic field imaging. As proof of concept, the authors image the magnetic field produced by CrTe2, a room-temperature van der Waals ferromagnet. This h-BN-based magnetic sensor offers high flexibility and the ability to be placed in atomic-scale proximity to a target sample, and thus is expected to find numerous applications in 2D materials research by offering a simple means to probe in situ the physics of van der Waals heterostructures.     LETTERS Letter High-Order Qubit Dephasing at Sweet Spots by Non-Gaussian Fluctuators: Symmetry Breaking and Floquet Protection Ziwen Huang, Xinyuan You, Ugur Alyanak, Alexander Romanenko, Anna Grassellino, and Shaojiang Zhu Phys. Rev. Applied 18, L061001 (2022) – Published 2 December 2022 The understanding and characterization of realistic noise are critical for assessing and reducing errors in qubits, but theoretical studies often overlook the different roles of Gaussian and non-Gaussian noise in reducing qubit coherence. The authors employ two theoretical approaches to inspect such differences in solid-state qubits, and find a symmetry-breaking effect that is unique to non-Gaussian noise and can be detected experimentally. They also propose a protocol that can significantly increase the coherence time. These findings provide simple yet powerful tools for detecting non-Gaussian noise as well as mitigating its detrimental effect on the qubits.     Editors' Suggestion Letter Magnetic Imaging with Spin Defects in Hexagonal Boron Nitride P.

Doty, and Sophia E. Economou Phys. Rev. Applied 18, L061003 (2022) – Published 21 December 2022 While multiphoton entangled states are the essential building blocks of quantum photonic technologies, large-scale production of such states has proven to be difficult. This study utilizes the unique structure of hole spins in quantum dot molecules to propose an approach that overcomes many of the existing obstacles in the deterministic generation of such states. With high fidelity and production rates that are unmatched among currently available protocols, this proposal seems quite promising as a basis for tomorrow's optical quantum communication hardware.     Letter Anderson-Higgs Mass of Magnons in Superconductor-Ferromagnet-Superconductor Systems Mikhail Silaev Phys. Rev. Applied 18, L061004 (2022) – Published 27 December 2022 The dynamic interplay of superconductivity and magnetism is promising for developing quantum magnonics and spintronics. Recent experiments have reported significant, enigmatic shifts of ferromagnetic resonance frequency in layered SFS structures. The author explains that the origin of this effect is spontaneous generation of magnon mass due to the celebrated Anderson-Higgs mechanism, a cornerstone of the Standard Model of particle physics. Upon cooling below the superconducting critical temperature, the magnons acquire a frequency gap and change their propagation direction. This effect enables the creation of magnon resonators, crystals, parametric amplifiers, and other useful devices.     ARTICLES Editors' Suggestion First-Principles Calculations of Shallow Acceptor-Carbon Complexes in Si: A Potential-Patching Method with a Hybrid-Functional Correction Jun Kang and Lin-Wang Wang Phys.

Applied 18, 064053 (2022) – Published 19 December 2022 Coherent one-way quantum key distribution (COW-QKD) is a popular cryptography protocol, due to its fairly simple implementation and passive measurement device. Its security analysis is challenging, though, and extra assumptions or modifications are typically employed. Here the authors propose minor modifications to COW-QKD's prepared states while retaining the original, fully passive measurement device, and generalize the "universal squashing" framework to analyze their system's security. The results suggest that performance should be comparable to upper bounds from the literature, making this protocol a viable alternative to one based on phase-modulated coherent states.     Ultrafast Buildup Dynamics of Terahertz Pulse Generation in Mode-Locked Quantum Cascade Lasers Feihu Wang, Xiaoqiong Qi, Valentino Pistore, Lianhe Li, Gary Agnew, Edmund Linfield, Giles Davies, Jérôme Tignon, Juliette Mangeney, Aleksandar D.

Applied 18, 064076 (2022) – Published 26 December 2022 Magnetic materials are a vital resource in designing energy-efficient information technologies. To try to learn how magnetism develops in ultrathin systems, we measure, but deducing the physics afterward is an ill-posed problem. This study uses neural networks to facilitate the reconstruction of the underlying magnetic textures of thin magnets through measurements of their stray fields. The technique is surprisingly robust to experimental noise, and can reliably reconstruct magnetism in arbitrary directions. Importantly, prior training of the network is not required, and the technique is broadly applicable for solving ill-posed inverse problems when the forward problem is well defined.     Editors' Suggestion Flows in Straws: Viscous Flows in One-Dimensional Metamaterial Peter Breitman, Michael Pukshansky, Anna Zigelman, Ezra Ben Abu, Ofek Peretz, Sefi Givli, and Amir D. Gat Phys. Rev. Applied 18, 064077 (2022) – Published 26 December 2022 The authors study the interaction between a viscous flow and a one-dimensional mechanical metamaterial composed of bistable unit cells, much like a drinking straw. Their twofold model shows excellent agreement with experimental results. While prior studies have focused on tailoring unit-cell structure to obtain a desired multistable behavior, here the viscous fluid allows tuning of rate-dependent properties and nonlocal interaction between unit cells. The ability to manipulate both structural and nonlocal rate-related properties points to the development of smart materials with tunable kinetic relations, large reversible deformations, and tailored dynamic properties.     Determination of the Complex-Valued Elastic Moduli of Polymers by Electrical-Impedance Spectroscopy for Ultrasound Applications William N.

Applied 18, 064081 (2022) – Published 27 December 2022 Unraveling the complex behavior of wet granular media has been challenging, because the effective stresses transmitted through the particles have remained unobservable. The authors use their recently developed extension of photoelasticity for coupled fluid-granular systems to image particle stresses during fracture by air injection in an oil-saturated granular pack. They discover two states of the granular medium evolving with the fractures, plus an "effective-stress shadow" behind the propagating fracture tips. This study points out the power of photoporomechanics for studying coupled fluid-solid processes in granular media, including energy recovery, gas venting, and geohazards.     Retention Model and Express Retention Test of Ferroelectric HfO2-Based Memory Vitalii Mikheev, Ekaterina Kondratyuk, and Anastasia Chouprik Phys.

Applied 18, 064088 (2022) – Published 28 December 2022 The kinetic inductance of charge carriers in disordered superconductors provides a broadband low-loss source of nonlinear electromagnetic response. This work investigates TiN nanowires as an alternative to Josephson junctions for applications involving elevated temperatures, higher frequencies, and strong magnetic fields. An extreme nanowire geometry for TiN microwave resonators leads to current-density concentration and enhanced self-Kerr coefficient, yielding a nonlinearity-to-loss ratio as high as 21% and quality factor exceeding 10,000. Such devices may find application in quantum frequency conversion of microwave photons, and with improvement might attain strong quantum nonlinearity.     Higher-Order Topological States in Photonic Thue-Morse Quasicrystals: Quadrupole Insulator and the Origin of Corner States Langlang Xiong, Yu Zhang, Yufu Liu, Yaoxian Zheng, and Xunya Jiang Phys.
