Local moments near the metal‐insulator transition
TL;DR: In this article, it is argued that the metallic state near the transition can be described by a phenomenological two-fluid model of local moments and itinerant quasiparticles.
A phase transition brought on by quantum fluctuations at absolute zero may seem like an abstract theoretical idea of little practical consequence. But it is the key to explaining a wide variety of experiments.

Journal ArticleDOI
STABLE hc/e VORTICES IN SUPERCONDUCTORS WITH SPIN-CHARGE SEPARATION
TL;DR: In this paper, a phenomenological model of the superconducting phase of systems with spin-charge separation and antiferromagnetically induced pairing is studied, and the low energy properties of a symplectic large-N expansion of a model of cuprate superconductors are argued to be well described by F.
Journal ArticleDOI
Detecting the quantum zero-point motion of vortices in the cuprate superconductors
TL;DR: In this article, the experimental implications of a theory of the quantum dynamics of vortices in two-dimensional superfluids proximate to Mott insulators are explored, using the spatial extent of such modulations in scanning tunnelling microscopy measurements on the vortex lattice of BSCCO to estimate the inertial mass of a point vortex.
Journal ArticleDOI
Impurity spin dynamics in 2D antiferromagnets and superconductors
TL;DR: In this article, the universal theory of localized impurities in the paramagnetic state of 2D antiferromagnets where the spin gap is assumed to be significantly smaller than a typical exchange energy is discussed.
