Let $G$ be a symmetry group, let $d$ be the spatial dimension, and let $\mathrm{Witt}(G\text{-TQFT}_d)$ be the Witt group of $d$-dimensional $G$-TQFTs. Let…

Let $T$ be a finite Abelian group, let $G$ be a finite symmetry group, and let $L$ be an MBL LIOM algebra in the MBL phase of the $T$-quantum-double model. Let $\mathcal{U}$ be a…

Let $G$ be a discrete group, let $\mathrm{B}G$ be its classifying space, and let $\mathrm{QCA}_{d+1}$ denote the proposed $(d+1)$-dimensional quantum-cellular-automaton spectrum. W…

Let $G$ be a finite group, let $d$ be the spatial dimension, and let $Q_{d-p}$ denote the relevant group of quantum cellular automaton classes. An MBL Hamiltonian has trivial spont…

Let $G$ be a symmetry group. The Witt group of $G$-TQFTs is obtained from symmetry-enriched topological orders modulo the relation identifying phases that admit gapped symmetric in…

Let $G$ be a finite group, and let $\mathcal{U}$ and $\mathcal{W}$ be $G$-representations. They are blend-equivalent if they are related by the lattice blending relation, and conju…
