Phys.org  January 21, 2020 In the XY model of a spin system used for solving complex problems particles form vortex-like patterns around multiple focal points. An international team of researchers (Japan, USA -Stanford University) improved an experimental set up that emulates the XY model by designing a laser system that generates pulses of light particles within a one-kilometer-long optical fiber cavity. The pulses generated 5,000 spins, i.e. flows of light particles going down 5,000 different drains, within the cavity. It enabled long simulations over several minutes within a stable system. This improves on previous oscillators that produced only 100 spins […]
