Free fermions behind the disguise
Samuel J. Elman, Adrian Chapman, Steven T. Flammia
An invaluable method for probing the physics of a quantum many-body spin system is a mapping to noninteracting effective fermions. We find such mappings using only the frustration…

Characterization of solvable spin models via graph invariants
Adrian Chapman, Steven T. Flammia
Exactly solvable models are essential in physics. For many-body spin-1/2 systems, an important class of such models consists of those that can be mapped to free fermions hopping on…
