Infinite number of quantum particles gives clues to big-picture behaviour at large scale

(Springer) In quantum mechanics, measuring both the position and speed of a particle at the same time is not possible. To identify a particle's characteristics, physicists introduced the notion of quasi-distribution of position and momentum. In a new study published in EPJ ST, Dr J.S. Ben-Benjamin and colleagues from Texas A&M University, USA, reverse this approach; starting with quantum mechanical rules, they explore how to derive an infinite number of quasi-distributions, to emulate the classi...
