Electric-field tunable generation of entangled photon pairs is achieved by spontaneous parametric down-conversion in a ferroelectric nematic liquid crystal, with an efficiency comparable to that of the best nonlinear crystals.
The Cavendish Laboratory’s director, Brian Pippard, comments on the landscape of physics research in 1974, plus the benefits of applying thermodynamics to physiology, in the weekly dip in Nature’s archive.
Deep-seated aspects of local research systems need to be uprooted to ensure that researchers in low-income countries can harness the advantages of open access.
Large language models could exhaust the supply of publicly available, human-crafted writing in the next two to eight years. Plus, AI model finds huge cache of potential antibiotics hidden in genomes and Microsoft’s algorithm predicts global air pollution in less than a minute.
