"Theoretically determining whether a finite system is topological is by itself ambiguous."
"The question of whether a finite sample is topological is as ambiguous as asking whether an exponentially small energy splitting is zero."

This new preprint [1] from @antonakhmerov.org and team demonstrates how Microsoft's theoretical definition of topology in their gap protocol can make "a trivial system appear topological".
Oh dear!

Help our friends at the NSF:
Seeking scientists based in California who are willing to attest to direct harm caused by NSF firings.
If you’re in the science world, please RT this to widen the net— a lawsuit on the unjust mass firings needs these comments.
(comment briefly here and I’ll follow up!)
