Researchers developed a novel method to predict physical phenomena without estimating parameters, reducing computational challenges. The new approach uses a multiparameter eigenvalue-problem emulator to directly predict unknown observables.
A new benchmark, V-score, has been developed to tackle quantum many-body problems. The V-score combines energy and fluctuation data into a single number, making it easier to rank different methods based on accuracy.
A team of physicists discovered that groups of just three zebrafish exhibit coordinated movement patterns similar to those in large schools. In contrast, pairs of fish behave differently, with one leading the other. The study's findings suggest that three is a critical number for group cohesion in schooling behavior.
