Modern high-speed internet uses light to quickly and reliably transmit large amounts of data through fiber-optic cables, but currently, light signals hit a bottleneck when data processing is necessary. For that, they must ...
Generative AI systems, such as ChatGPT, are trained on large datasets to create written, visual or audio content in response to prompts. When fed real images, some algorithms can produce fake photos and videos known as deepfakes.
In recent years, many physicists and materials scientists have been studying a newly uncovered class of magnetic materials known as altermagnets. These materials exhibit a unique type of magnetism that differs from both conventional ...
As our digital world generates massive amounts of data—more than 2 quintillion bytes of new content each day—yesterday's storage technologies are quickly reaching their limits. Optical memory devices, which use light to read ...
A group of Nagoya University researchers in Japan has synthesized 4- and 5-layered versions of the important electrical material perovskite. Analyzing the mechanism of ferroelectricity in the material, they found it has a ...
Using two optically-trapped glass nanoparticles, researchers observed a novel collective Non-Hermitian and non-linear dynamic driven by non-reciprocal interactions. This contribution expands traditional optical levitation ...
A research team has constructed a coherent superposition of quantum evolution with two opposite directions in a photonic system and confirmed its advantage in characterizing input-output indefiniteness. The study was published ...
An updated model reconciles the gap between recent experiments and theory concerning polarization in wurtzite semiconductors—paving the way for the development of smaller, faster and more efficient electronic devices, according ...
Photonic alloys, alloy-like materials combining two or more photonic crystals, are promising candidates for the development of structures that control the propagation of electromagnetic waves, also known as waveguides. Despite ...
In physics, nonreciprocity occurs when a system's response varies depending on the direction in which waves or signals are propagating within it. This asymmetry arises from a break in so-called time-reversal symmetry, which ...
