Let a gapped invertible topological phase of matter be a phase with fixed dimension and symmetry type, and let an invertible field theory (IFT) be its low-energy limit. Low-energy…

SPT-cobordism conjecture. The particular loop spectrum that appears is the Anderson dual of the Thom spectrum.

Let $alpha ^0$ and $alpha ^1$ be the invertible field theories whose partition functions are the exponentiated eta-invariants formed from the operators $D^0$ and $D^1$, respectivel…
