Agrawal, and Dalziel J. Wilson Phys. Rev. Applied 19, 024011 (2023) – Published 3 February 2023 Cavity optomechanical accelerometers promise ultrahigh sensitivity, in situ calibration, and radiation-pressure stabilization for e.g. chip-scale gravimetry or dark-matter searches. However, platforms that meet the unique technical demands are difficult to fabricate. The authors demonstrate a simple, scalable setup with an optical cavity based on a pair of vertically integrated Si3N4 membranes of different stiffnesses. Radiation-pressure cooling of membrane motion enables resolution of chip acceleration to better than 10−7g, over a bandwidth of several kilohertz. A cryogenic array of these devices could be used to search for weak inertial forces due to dark matter.     Editors' Suggestion Metastable Defects Decrease the Fill Factor of Solar Cells Thomas Paul Weiss, Omar Ramírez, Stefan Paetel, Wolfram Witte, Jiro Nishinaga, Thomas Feurer, and Susanne Siebentritt Phys. Rev. Applied 19, 024052 (2023) – Published 17 February 2023 Solar cells are made from semiconductors, which inevitably include defects. The defects in Cu(In,Ga)Se2 (CIGS) are known to be metastable: With excitation they change character, which can have a profound impact on device function. The authors show that these metastable defects reduce the efficiency of the solar cell due to an increased diode factor. It is possible to measure this quantity directly from the bare absorber (without needing to build the entire solar cell), yielding a lower limit for the whole device. Experiments and simulations indicate that metastable defects must be reduced to increase efficiency, and not just in CIGS-based solar cells.     Editors' Suggestion Multiscale Modeling of Metal-Oxide-Metal Conductive Bridging Random-Access Memory Cells: From Ab Initio to Finite-Element Calculations Jan Aeschlimann, Fabian Ducry, Christoph Weilenmann, Juerg Leuthold, Alexandros Emboras, and Mathieu Luisier Phys. Rev. Applied 19, 024058 (2023) – Published 22 February 2023 Continuum modeling is a popular, computationally efficient technique that can shed light on the resistance-switching properties of conductive bridging random-access memory (CBRAM) cells. Traditional models typically rely on many fitting parameters, but this approach uses material parameters extracted either from either ab initio or machine-learned empirical calculations. As proof of concept, the authors apply the computational framework to an SiO2-based CBRAM cell, and reveal the relevance of Joule heating in nanoscale devices. With the proposed multiscale methodology it is possible to explore the potential of not-yet-fabricated memory cells, and to optimize their design reliably.     Editors' Suggestion Multiple Tin-Vacancy Centers in Diamond with Nearly Identical Photon Frequency and Linewidth Yasuyuki Narita, Peng Wang, Keita Ikeda, Kazuki Oba, Yoshiyuki Miyamoto, Takashi Taniguchi, Shinobu Onoda, Mutsuko Hatano, and Takayuki Iwasaki Phys. Rev. Applied 19, 024061 (2023) – Published 23 February 2023 Tin-vacancy (Sn-V) centers in diamond, which possess good optical and spin properties, are a promising system for constructing quantum network nodes. Tin atoms are heavy, though, and generating photons with identical wavelength and linewidth from multiple Sn-V emitters is challenging, due to the strain in the diamond host material. This study shows that multiple Sn-V centers, formed deep within bulk diamond by ion implantation and high-temperature annealing, emit nearly identical photons. This leads to two-photon interference from distant centers, an important step toward building quantum network nodes.     Editors' Suggestion High-Fidelity CNOT Gate for Donor Electron Spin Qubits in Silicon Ludwik Kranz, Stephen Roche, Samuel K. Gorman, Joris. G. Keizer, and Michelle Y. Simmons Phys. Rev. Applied 19, 024068 (2023) – Published 24 February 2023 Epitaxial atom-based spin qubits in silicon exhibit excellent properties, and benefit from the outstanding scalability of that material platform. As silicon spin-based qubits now start to meet the 99% fault-tolerance threshold, the authors show how the nuclear spins inherent to the local magnetic environment can be engineered as atomic magnets to boost the fidelities of two-qubit logic gates. Modeling indicates that two-qubit CNOT gate fidelities as high as 99.98% are realistic, through silicon purification and careful engineering. This work provides a roadmap for atom qubits in silicon, showing how to optimize two-qubit gates at both the design and measurement stages.     LETTERS Letter Experimental Realization of a Colloidal Ratchet Effect in a non-Newtonian Fluid Guillermo Camacho, Alejandro Rodriguez-Barroso, Oscar Martinez-Cano, Jose R. Morillas, Pietro Tierno, and Juan de Vicente Phys. Rev. Applied 19, L021001 (2023) – Published 21 February 2023 The transport of matter via a ratchet effect represents a convenient way to extract useful work from a thermodynamic system, and can have direct applications in several microscale fluid-based technologies. Most realizations so far have been centered on using Newtonian fluids. This study shows how to achieve directed transport of magnetic microparticles in a non-Newtonian shear-thinning fluid under a square-wave magnetic force. This technique could be used in active microrheology, to infer the nonlinear properties of viscoelastic media.     ARTICLES Band Alignment and Photoresponse of LaFeO3-Based Heterojunctions Yunwei Sheng, Mathieu Mirjolet, Mario Villa, Jaume Gàzquez, José Santiso, Andreas Klein, Jordi Fraxedas, and Josep Fontcuberta Phys.
