Free phases of Majorana fermions: Tenfold ways compared
Luuk Stehouwer
We provide a mathematically rigorous classification of symmetry-protected topological (SPT) phases of neutral free fermions. Our approach utilizes Karoubi triples with negative squ…

Is Crane--Yetter fully extended?
Luuk Stehouwer
We revisit the question of whether the Crane-Yetter topological quantum field theory (TQFT) associated to a modular tensor category admits a fully extended refinement. More specifi…

SKK groups of manifolds and non-unitary invertible TQFTs
Renee S. Hoekzema, Luuk Stehouwer, Simona Veselá
This work considers the computation of controllable cut-and-paste groups of manifolds with tangential structure . To this end, we apply the work o…
