Description:

Abstract: Electrons create magnetic fields, so materials that manifest quantum-mechanical and strongly correlated electron behavior must have magnetic signatures. Although distinctive, interesting, and informative, these magnetic signals are hard to measure. In this talk, I will take you on a tour of mesoscopic magnetic phenomena. We will visit metallic rings that exhibit persistent currents despite having a finite resistance; see images of superfluid density that provides clues to the origin of superconductivity; view landscapes of paramagnetism, ferromagnetism, conductivity and superconductivity in exotic materials; and manipulate quantum vortices, one-dimensional elastic objects moving through energy landscapes. These advances in nanomagnetic imaging provide insight into the interplay of disorder, order, and dimensionality in quantum-mechanical phase-coherent states in real materials.
