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.

    For 25 years of condensed matter science, physicists have searched for a material that realizes a macroscopic quantum state of matter: the quantum spin liquid. Recent experiments show that a necessary interaction may be found in a family of hexagonal ruthenium-based materials.
