Quantum fluids and solids

Definition

Quantum fluids and solids are substances in which the interaction between the constituent atoms or molecules is governed by the laws of quantum mechanics. The properties of these materials are strongly influenced by the motion of atoms even in their lowest energy state, known as zero-point motion.
