Quantum fluids and solids

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.

    Symmetry-allowed topological defects, like quantized vortices, often control the universal behavior of macroscopic quantum systems. Here, Mäkinen et al. report survival of half-quantum vortices in symmetry-breaking transitions to polar-distorted phases in nanostructure-confined superfluid 3He.

    The emergence of superconductivity from the normal state in the cuprates above the transition temperature (Tc) has been controversial. Here, Pelc et al. report nonlinear conductivity, resulting from superconducting precursors only, vanishing exponentially above Tc both with temperature and with magnetic field.

    Applications of spintronics often require angular momentum to be moved from place to place. A possible observation of spin superfluidity may point the way toward the transport of spin angular momentum across an insulating sample with no dissipation or energy loss.
