Detecting the quantum zero-point motion of vortices in the cuprate superconductors

چکیده
We explore the experimental implications of a recent theory of the quantum dynamics of vortices in two-dimensional superfluids proximate to Mott insulators. The theory predicts modulations in the local density of states in the regions over which the vortices execute their quantum zero point motion. We use the spatial extent of such modulations in scanning tunnelling microscopy measurements (Hoffman et al , Science 295, 466 (2002)) on the vortex lattice of Bi2Sr2CaCu2O8+δ to estimate the inertial mass of a point vortex. We discuss other, more direct, experimental signatures of the vortex dynamics.

متن کاملThermodynamics and quantum criticality in cuprate superconductors
We will present elementary scaling arguments focused on the thermodynamics in the proximity of the quantum critical point in the cuprate superconductors. Extending the analysis centered on the Grüneisen parameter by Rosch, Si, and co-workers to the cuprates, we demonstrate that a combination of specific-heat and chemical potential measurements can reveal the nature of the zero temperature singu...
متن کاملQuantum critical scaling at the edge of Fermi liquid stability in a cuprate superconductor.
In the high-temperature cuprate superconductors, the pervasiveness of anomalous electronic transport properties suggests that violation of conventional Fermi liquid behavior is closely tied to superconductivity. In other classes of unconventional superconductors, atypical transport is well correlated with proximity to a quantum critical point, but the relative importance of quantum criticality ...
متن کاملMagnetic structure factor in cuprate superconductors: Evidence for charged meron vortices
In this paper we demonstrate that a ground state consisting of a quantum liquid of merons and antimerons can quantitatively describe the position and orientation of the incommensurate peaks observed in elastic neutron scattering on cuprates, with essentially no free or adjustable parameters. At small dopings, the relevant length scale is the transverse size of a meron-antimeron pair, defined by...

htp:// D ow nladed fom Maximizing the sustainable supercurrent density, JC, is crucial to high-current applications of superconductivity. To achieve this, preventing dissipative motion of quantized vortices is key. Irradiation of superconductors with highenergy heavy ions can be used to create nanoscale defects that act as deep pinning potentials for vortices. This approach holds unique promise...
