Though permanent magnets are ubiquitous in science and everyday society, we still lack a systematic analysis of how to optimally place and orient a large set of them in a (much larger) set of possible locations. This study reformulates the problem in terms of sparse regression, and offers an algorithm that can effectively solve the problem for nonconvex systems with over 10 optimizable variables and constraints. The authors then obtain high-performance designs for a class of familiar fusion-power devices called stellarators. Because their algorithm addresses problems that appear across many scientific domains, it should prove extremely impactful.

The visualization of objects such as transparent living cells and tissues plays an important role in biological research. However, weak scattering and absorption of “phase objects” make it challenging to obtain high-contrast images, and phase-contrast techniques are needed. This study proposes differential microscopy based on the photonic spin Hall effect at a simple glass interface. The combination of the photonic spin Hall effect and a bright-field microscope can perform spatial differentiation on the phase distribution, which leads to a low-cost differential interference contrast (DIC) system.

Conventional semiconductor lasers require population inversion to stimulate light emission. Polariton lasers, on the other hand, emit coherently in a regime without population inversion. This working regime was initially demonstrated indirectly in vertical cavity systems, and now the present work uses a waveguide geometry to provide direct proof, emphasizing the absence of reciprocity between absorption and stimulated processes within the laser cavity. Moreover, thanks to strong polaritonic gain, this laser features injection sections much shorter than those in standard edge-emitting lasers, opening the door to tighter on-chip integration and multiple functionalities within a cavity.

Deep-subwavelength sound-absorbing platforms with ventilation have demonstrated scientific significance and promising applicability. Available designs have remained severely restricted by the limited dissipation mechanisms for plane wavefronts, and elaborate geometries configured by extensive parametric sweeps. This work proposes a paradigm to realize a dissipated-sound metamaterial cage that can perfectly absorb omnidirectionally radiated cylindrical sound, via hybridizing resonant meta-atoms with geometrical parameters optimized by an inverse-design strategy. The proposal provides a perspective for designing a ventilated absorber to dissipate low-frequency sound.

Compact and scalable sources of broadband polarization entanglement at telecommunication wavelengths will pave the way for multiuser long-distance quantum communication at enhanced data rates, but progress toward this goal has been hindered due to large birefringence in conventional silicon-on-insulator nanowaveguides. The authors theoretically demonstrate, via dispersion engineering, the successful generation of polarization-entangled photon pairs over a broad range of wavelengths. This work also provides a strategy to avoid entanglement degradation due to polarization-mode dispersion. The proposed devices will be useful building blocks for large-scale quantum communication networks.

The quantum Internet will support paradigm shifts in cybersecurity, distributed quantum computing, and sensing. Its realization, however, has been held back by the lack of practical technologies to enable deployment and scalability. To date, most demonstrations have been limited to laboratories with expensive resources such as cryogenic and vacuum systems. The authors overcome this challenge by designing a field-deployable quantum memory, based on warm atomic vapor, that demonstrates high-fidelity performance and robustness to environmental noise. This represents a key technology for distributing quantum entanglement across large-scale quantum networks.

Hybrid photonic-plasmonic cavities based on nanoparticle-on-a-mirror structures simultaneously provide ultralow mode volume and high -factor, and so a very large Purcell factor, which is a key measure of light-matter interaction. Operation of such cavities has been constrained to wavelengths below 1 μm, with the technologically relevant telecom regime remaining elusive. This study describes a hybrid cavity operating at telecom wavelengths. The proposed design leads to extremely large Purcell factors (~10–10), and could impact many different applications, such as molecular optomechanics, bio- and chemosensing, efficient quantum emitters, and enhanced Raman spectroscopy.

Quantum cascade lasers operating at THz frequencies can fill the gap between conventional electronic and optical devices, but still need substantial cooling. The authors conduct a detailed analysis of today’s high-performing devices using nonequilibrium Green’s function method, and identify the shortcomings of these devices. They also demonstrate a convenient way to study the current injection, which is a limiting factor of the device’s performance. These approaches lead to the suggestion and design of an improved device that operates at 265 K, which requires less cooling.

Accessibility to the microkelvin temperature regime is important for quantum technology research. Cryogen-free dilution refrigerators opened up the millikelvin temperature range, but the perception is that ultralow temperatures are difficult to reach and require specialist infrastructure. The authors report the design of a microkelvin platform based on a nuclear-demagnetization stage, engineered and optimized for operation on a cryogen-free dilution refrigerator. The study demonstrates temperatures as low as 395 K, and a protocol that enables experiments operated below 1 mK for 95% of the time, providing an efficient cryogen-free microkelvin environment for a wide range of applications.
