The super insulator: a new topological state of matter

In a loop of superconducting wire, electric current can flow indefinitely without a power supply.
Can we have batteries that do not loose energy when not in use?
Superinsulators, materials that have infinite resistance, have been theoretically predicted in 1996 and experimentally observed in 2008. They correspond to the confining phase of a topological field theory containing a mixed Chern-Simons term and they represent thus an experimentally accessible toy model to understand confinement in QCD.
