Persistent Currents

Microcantilevers as probes of closed mesoscopic systems Fabricating a sub-micron circuit on the end of a cantilever allows us to study it in isolation. In-situ electron thermometry Monitoring the devices superconducting transition makes it possible to determine the temperature of the isolated metal ring. Persistent currents in normal-metal rings A number of important questions remain unanswered about the properties of dissipationless currents flowing through resistors.
