This APL special topic is dedicated to a fascinating class of systems that contain magnetic elements at length scales in the range of a few nm up to a few…

Quantum photonic applications such as photonic quantum computing, quantum communication, and quantum sensing require highly sophisticated non-classical light sources and high-efficiency single-photon detectors. The light sources should be able to…

In recent years, there has been a growing interest in realizing artificial metasurfaces and metamaterials that provide novel and on-demand physical properties. Such metastructures can be designed on a variety…

Van der Waals (vdW) materials represent a versatile material platform to explore fundamental science of correlated phases (e.g. Mott insulator, superconductivity, and magnetism) and new electronic and photonic devices. When…

Traditional silicon solar cells reach their efficiency limit, yet the massive upscaling of photovoltaics required to provide a significant contribution of solar power to the primary energy demand requires a…

The charge-density-wave (CDW) phase is a macroscopic quantum state consisting of a periodic modulation of the electronic charge density accompanied by a periodic distortion of the atomic lattice. Unconventional forms…

For decades, the field of thermoelectricity has been dominated by inorganic materials. The demonstration of reasonably stable polymer-based materials with a figure of merit of 0.1 and above has triggered…

Commerce depends on communications technology now more than ever, demanding improved connectivity, bandwidth, data rates, and latency to grow productivity. With the introduction of 5G technology to the marketplace, new…

Solution processed lead halide perovskites demonstrated unprecedented success in solar cell applications thanks to their defect tolerance and facile solution-based processing. Global scaleup and acceptance by consumers, however, requires further…
