Moreno Posted September 4, 2017 Posted September 4, 2017 Scientists claim that they discovered a superinsulating state of matter. What is it actually? https://arxiv.org/pdf/1209.0530.pdf Does it imply an infinite dielectric strength, an infinite dielectric permittivity or neither? I suggest its insulating properties still can't be literally infinite, what are more realistic limits of that stuff?
Strange Posted September 5, 2017 Posted September 5, 2017 Apparently it isn't known if permittivity is infinite or not: https://en.m.wikipedia.org/wiki/Superinsulator

You can test this by running a AC current instead of DC current into a superconductor. Edited October 2, 2017 by Vmedvil
