We consider quantum error-correcting subsystem codes whose gauge generators realize a translation-invariant, free-fermion-solvable spin model. In this setting, errors are suppressed by a Hamiltonian whose terms are the gauge generators of the code an

Exactly solvable models are essential in physics. For many-body spin-$\mathbf{\sf{1}/{2}}$ systems, an important class of such models consists of those that can be mapped to free fermions hopping on a graph. We provide a complete characterization of

In 1968, the Scottish Beat novelist Alexander Trocchi hosted an evening in London entitled “The State of the Revolt.” He was joined by the Glaswegian countercultural psychiatrist R. D. Laing and th...

This article explores archival accounts of the experimental community, Kingsley Hall (1965-70), established by R. D. Laing, the radical Scottish psychiatrist. The paper contributes to renewed interest in Kingsley Hall, R. D. Laing's radical psychiatr

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 graph $G$ of a Hamiltonian $H$, i.e., the network of anticommutation r

Almost 50 years after his death, R. D. Laing, once the counterculture’s favorite psychiatrist, and, indeed, for a while the best-known psychiatrist in the world, is once again the subject of intere...
