Yale scientist Nikhil Malvankar's research on bacteria's nanowires reveals that electrons can move rapidly via quantum effects at room temperature, offering potential insights for advancing quantum computing technology by mimicking nature's efficient electron transfer mechanisms.
Researchers developed a tellurium nanowire-based retinal prosthesis that restores partial vision in blind mice and enables near-infrared detection in primates, marking a significant advancement in artificial vision technology with potential applications for humans.
Researchers studying strange metals have discovered evidence that challenges our understanding of electrical currents. By conducting quantum measurement experiments on nanowires made of ytterbium, rhodium, and silicon, they found that the behavior of electrical currents in strange metals differs from that of normal metals. Instead of quasiparticles, the researchers observed a more liquid-like flow of charge, suggesting that the traditional model of quasiparticles may not apply in these materials. The findings support a theory proposed over 20 years ago and raise questions about how charge moves collectively in strange metals.
Researchers at the University of Basel and Lund University have generated superconducting pair states of electrons on nanowires, separated by barriers. By manipulating the height of the barriers, the researchers observed different types of pair states, including individual Andreev bound states (Andreev atoms), coupled Andreev bound states (Andreev molecules), and fused pair states that conduct electrical current without dissipation (Andreev helium). These findings provide insights for the development of new quantum states and potential applications in quantum computers.
Scientists at the University of Massachusetts Amherst accidentally discovered a way to generate a small electric current from humidity in the air while attempting to create a simple sensor. The device, made from nanowires, produced an electrical signal even without being powered, leading to a breakthrough in renewable energy research.
Researchers at the University of Basel have cast doubt on Microsoft's recent research results regarding the detection of Majorana particles, which could be used as particularly robust quantum bits in quantum computers. The Basel team showed that the findings could also be explained by other effects that have nothing to do with Majorana particles. The researchers concluded that both the current anomaly and the superconducting properties can be reproduced by a small amount of disorder from impurities inside the nanowire.
