The topological properties of an acoustic metamaterial’s phononic band structure would be useful for developing functional acoustic and thermal devices. While previous demonstrations of topological properties have been limited to low-frequency airborne sound, high-frequency acoustic waveguides utilizing the topological edge state are increasingly in demand for quantum technologies, sensing, and microwave communication. In this work, the authors use innovative microscopy to visualize topological acoustic edge states at frequencies as high as 2.4 GHz on a patterned substrate, which bodes well for the feasibility of topological surface-acoustic-wave devices.

Heart failure is a progressive pathology that represents the main life-threatening cardiac disease. Its models are typically based on clinical observations and are not consistently predictive. This study employs an approach based on both fluid dynamics and solid mechanics to uncover the flow-tissue interplay that may anticipate the development of heart failure. The physiological fluid-structure interaction is analyzed in children with a single right ventricle (SRV), where the right ventricle has been surgically transformed to take on the role of an underdeveloped left ventricle. The results provide a physics-based explanation for the observed clinical outcome in these patients.

Thick Ge/(Si,Ge) multiple-quantum-well heterostructures are interesting for silicon-integrated optoelectronic devices operating in the midinfrared and terahertz spectral regions. The epitaxy of such structures becomes increasingly challenging as their thickness increases, due to the accumulation of strain and defects. This study proves that ultrahigh-vacuum chemical vapor deposition allows for subnanometer control of the compositional profile throughout micrometer-thick strain-compensated multilayered structures with very low defect density. Here terahertz spectroscopy plus numerical simulation allows characterization at higher sensitivity and resolution than standard techniques.

In a circulating cavity magnon polariton (quantized spin wave plus photon, resonating in a microwave chamber), the hybrid state and a noninteracting photonic state rotate in opposite directions—an important phenomenon for generating chiral states of electromagnetic modes in cavity magnonics and microwave engineering, to impart angular momentum upon standing waves. This study demonstrates the unidirectional nature of the mode propagation, paving the way for the generation of a high-power microwave beam with high coherence and narrow bandwidth. The authors also demonstrate how the unidirectional mode propagation results in nonreciprocity of the mode’s transmission amplitudes and phases.

Offering a potential pathway to the fantasy of invisibility, cloaking has been a most popular concept since its introduction over 15 years ago. This article furthers the concept by making the cloak transmittable, so as to allow “transmitting without being seen”. This special cloak consists of a concentric set of bianisotropic metasurfaces with a nonreciprocal innermost element, and allows the entity sitting at its center to transmit information at will in a desired direction while remaining invisible in all other directions. Such cloaks may find application in e.g. stealth technology, blockage avoidance, optical illusion, and cooling.

Spin-charge interconversion phenomena are important ingredients for the development of post-CMOS spin-based logic and magnetic memory technologies. Device design is often limited, though, by the fact that in most systems conversion occurs only if charge current, spin current, and spin polarization are mutually orthogonal. The authors find that in graphene/MoTe van der Waals heterostructures, charge currents injected in any spatial direction contribute to the same particular spin-polarization direction, thanks to a combination of strong spin-orbit proximity effects and broken crystal symmetries. This insight points to efficient spin-current generation and flexible device design.

Spin torque induced by orbital current has become of great interest, as it allows the use of lighter elements in the development of advanced spin-orbitronic devices. Meanwhile, the inverse orbital torque (IOT) effect, in which an orbital current creates a charge current, has been difficult to detect. This study uses pumped spin-orbital current in YFeO/Pt/CuO heterostructures to investigate the IOT effect. Mixed spin-orbital states propagate to the Pt/CuO interface and create a much stronger transverse charge current than that created without the CuO coating. This inverse orbital Rashba-Edelstein effect can be used to advance applications in spintronics.

Thermal regulation is crucial in modern electronics, but how to augment the thermal-switching ratio of high-performance heat regulators is still a puzzle that limits applications. In this kirigami-inspired study, a mechanical metamaterial made of nitrogen-doped porous graphene is designed to achieve an impressively high thermal-switching ratio. The high ratio comes from a chiral folding-unfolding deformation, which induces a metal-insulator transition that switches the primary heat carriers from electrons to phonons. This work provides a design paradigm to bridge the gap between kinematics and functional metamaterials and promote the development of high-performance thermal regulators.

Finding a path toward efficient multiphoton entanglement generation would boost both foundational studies and practical applications of quantum entanglement in e.g. quantum computation, metrology, and communication. The common approach has a notorious problem of exponentially decreasing success probability with increasing photon number, so another method is needed for scalability. This Letter presents a scheme for creating -photon entangled states with an exponential efficiency-enhancement factor of without spoiling the entanglement. Even with just the currently demonstrated multiplexing power, applying this method to state-of-the-art 12-photon states would yield an enhancement factor of 10.

A high-frequency nanoelectromechanical system (NEMS) based on a graphene membrane is a candidate for sensing applications, as well as a platform for fundamental research, but detecting such high-frequency oscillations of small membrane displacement is technically challenging. The authors integrate a high-sensitivity transistor with a multilayer graphene NEMS and drive the transistor via double resonant circuits at an electrical resonance. By optimizing the resonant circuits and driving the transistor with an rf signal, the high-frequency NEMS signal can be detected. This technique is useful for realizing NEMS applications at subgigahertz or higher frequencies.

Beyond those nonlocal metasurfaces that utilize such radiation coupling to promote efficiency in wave manipulation, in this study the coupling effect also serves as a powerful tool for engineering the spectrum, showcased by an acoustic open metasurface that allows airflow while blocking sound in a dramatically extended frequency band. This finding offers an efficient approach for broadband wave manipulation in a hybrid nonlocal manner.

Spin torque induced by orbital current has become of great interest, as it allows the use of lighter elements in the development of advanced spin-orbitronic devices. Meanwhile, the inverse orbital torque (IOT) effect, in which an orbital current creates a charge current, has been difficult to detect. This study uses pumped spin-orbital current in YFeO/Pt/CuO heterostructures to investigate the IOT effect. Mixed spin-orbital states propagate to the Pt/CuO interface and create a much stronger transverse charge current than that created without the CuO coating. This inverse orbital Rashba-Edelstein effect can be used to advance applications in spintronics.
