Contactless manipulation of particles and cells using acoustic forces that can be adjusted in real time is now important in biomedical sensors, imaging devices, and diagnostic tools. Dynamic manipulation typically requires huge phased arrays with complex electrical control, or a moving source with an inflexible displacement platform, but here the authors develop a method using an acoustic field modulated by a phononic crystal plate (PCP) in an acoustofluidic channel. PCP resonance-based dynamic manipulation via a single source, by switching the frequency, has the advantages of being simple, disposable, scalable, and combinable with a microfluidic chip.

Realizing direction-dependent energy responses greatly benefits the construction of switching and logic devices. This study proposes an archetype for an acoustic resonant-tunneling diode, made of mode-selective resonant metamaterial. Using this material, the authors experimentally demonstrate a broadband, high contrast ratio and single-mode unidirectional sound tunneling. This result is expected to impact control methodology in biomedical ultrasonography, acoustic communication, sound identification, and noise control.

The quantum logic between single photons lies at the foundation of deterministic, scalable quantum information processing. However, practical implementation suffers from weak optical nonlinearity, and gate fidelity is intrinsically limited by phase noise and spectral mixing. The authors address these concerns by utilizing an ultrahigh- photonic microcavity with nonlinearity. Two-photon spontaneous emission is thoroughly suppressed by shutting off the coupling channels between this artificial atom and the continuum states of a waveguide. This promising scheme for room-temperature operation is almost within reach of current experiments, and can be generalized to other systems.

Sensing vector magnetic fields is important to many applications in fundamental physics, bioimaging, and materials science. Sensors exploiting nitrogen-vacancy (N-) centers typically interrogate N- ensembles oriented in all directions, thwarting nanoscale spatial resolution. Utilizing the level anticrossing in the triplet ground state, the authors demonstrate a vector magnetometer that simultaneously measures all Cartesian components of the field, offering wide-band operation and high, equal sensitivity in all directions. This technique may work for single N- centers as well as ensembles, extending vector measurements to the nanoscale, at ambient temperatures.

Nonlinear dielectric materials are interesting because their properties can be dynamically reconfigured by an applied field. Even as understanding of their static properties advances rapidly, their dynamics remain much more difficult to predict and control, and experiments are hindered by the difficulty of millimeter-wave electrical characterization. The authors provide a broadband approach to nonlinear dielectric characterization that is widely generalizable, makes few assumptions about the sample, and yields details about the dynamics that are usually inaccessible. Such information about the physics of nonlinear dielectrics will promote millimeter-wave electronics.

On-chip signal transmission in both the classical and quantum regimes would benefit from broadband nonreciprocity (strictly one-way transmission) to overcome signal instabilities and enhance channel capacity. Engineering such nonreciprocity in integrated microwave circuits has long been a challenge. This study utilizes strong coupling between chiral microwave photons and magnons, those collective excitations of magnetization, to break time-reversal symmetry and increase the nonreciprocity bandwidth by two orders of magnitude. This approach is promising for an emerging class of nonreciprocal devices for coherent information processing.

This study proposes a hybrid system using an underlayer of magnetic thin film to couple and strengthen the magnetic interaction via spin waves.

This hybrid system offers a fresh approach to band-structure engineering for reconfigurable magnonic crystals.

Magnetic skyrmions are topologically protected spin textures of great interest for nanoscale information storage and processing. However, stabilizing small skyrmions without applying an external magnetic field remains challenging. This study employs a thin ferromagnetic layer exchange-biased by an antiferromagnetic film to stabilize ferromagnetic skyrmions around 60 nm in diameter, at zero magnetic field. In such a magnetic structure, exchange bias enhances skyrmion stability against external magnetic field perturbations, making this a promising platform for spintronic devices.

Converting heat into electricity using thermophotovoltaic cells is of growing interest, and currently works for sources hotter than 700 K, considering the band gap of an absorber material. Using narrower band gaps, though, would spoil the rectification of the desired junctions. To address this dilemma, the authors develop cells with heterojunctions of -BiTe thin films on -Si wafers. The narrow band gap of BiTe allows for absorbing lower-temperature radiation, while the large difference in Fermi levels between it and Si preserves rectification. Experiments prove that these cells can produce electricity even for a source at just 300 K.

The unique combination of properties found in InSb two-dimensional electron gases (2DEGs)—high electron mobility, strong spin-orbit interaction, large Landé factor, and small effective mass—makes them an attractive platform for a variety of mesoscopic phenomena. However, technical challenges have left quantum confined systems in these 2DEGs relatively unexplored. The authors overcome these challenges and perform a detailed study of stable, gate-defined quantum dots in InSb 2DEGs. Their results make an important contribution toward creating stable nanoscale devices in high-spin-orbit materials, particularly in the context of topological superconductivity.

Acquiring the information transmitted via channels with a single receiver is an important capability in electromagnetic imaging and sensing, for example, due to the cost associated with each receiver. A counterintuitive possibility consists of scrambling the pieces of information in multiple, distinct ways by letting waves propagate through a chaotic system in different configurations. Judiciously chosen configurations of a chaotic microwave cavity, reconfigurable via a tunable metasurface reflectarray, yield optimal information retrieval with a single port. This approach may also be translated to other wave phenomena, such as optical multiplexing in multimode fibers.

The generation of single photons serves as the backbone for tasks in quantum information processing. Generating quantum electromagnetic fields on highly dispersive platforms is technically challenging, though, due to phase-matching constraints. The authors consider the silicon photonic platform, due to its potential scalability, and demonstrate that phase matching is possible with highly dispersive transverse-magnetic polarized light, via nonlinear coupling of two racetrack-style microresonators. With its brightness and tunability, this source may have a significant impact on creation of entangled photons in photonic integrated circuits, for use in quantum information and communication.

Graphene is a tunable plasmonic material, and the resonance of graphene split-ring resonators (SRRs) is predicted to induce very strong field confinement. Recent years have seen many studies of graphene-based SRRs with analytical calculations and numerical simulations, yet without experimental demonstration, due to practical challenges in sample preparation and measurement. This is where the authors have succeeded, by producing tunable, ultracompact SRR arrays based on graphene. Their work experimentally bridges the gap between graphene and magnetic metasurfaces in the terahertz regime, making significant progress toward multifunctional graphene-based metasurfaces.

Contactless manipulation of particles and cells using acoustic forces that can be adjusted in real time is now important in biomedical sensors, imaging devices, and diagnostic tools. Dynamic manipulation typically requires huge phased arrays with complex electrical control, or a moving source with an inflexible displacement platform, but here the authors develop a method using an acoustic field modulated by a phononic crystal plate (PCP) in an acoustofluidic channel. PCP resonance-based dynamic manipulation via a single source, by switching the frequency, has the advantages of being simple, disposable, scalable, and combinable with a microfluidic chip.

Magnetic skyrmions are topologically protected spin textures of great interest for nanoscale information storage and processing. However, stabilizing small skyrmions without applying an external magnetic field remains challenging. This study employs a thin ferromagnetic layer exchange-biased by an antiferromagnetic film to stabilize ferromagnetic skyrmions around 60 nm in diameter, at zero magnetic field. In such a magnetic structure, exchange bias enhances skyrmion stability against external magnetic field perturbations, making this a promising platform for spintronic devices.
