Mysterious Behavior of Quantum Liquid Elucidated, a World 1st

Left: In a single particle system, the behavior of the particle is well understood by solving the Schrödinger equation. Here the particle possesses wave nature characterized by the de Broglie wave length. Right: In a many particle system, on the other hand, the particles interact each other in a quantum mechanical way and behave as if they are "liquid". This is called quantum liquid whose properties are very different from that of the single particle case. Credit: Image courtesy of Osaka University
