Left: scanning tunneling microscope image showing
"native defects" on the
surface of a high-Tc superconductor. [Hudson et al.,
1999]. How are such states related to bulk transport, and what kind of
information can be extracted from the electronic "ripples" they create?
Quasiparticles in the vortex state
Left: STM image of the vortex state of NbSe2
[Upward et al, Delft]. How does energy propagate in the vortex
lattice state? What are the main sources of
quasiparticle scattering?
Nanoscale superconductivity
Right: artificial grain boundary between two
YBCO crystallites [Mannhart group 2003].
How is unconventional
pairing in small grains, quantum wires and at interfaces different?
