The damage spreading transition: a hierarchy of renormalization group fixed points
Adam Nahum, Sthitadhi Roy
Deterministic classical cellular automata can be in two phases, depending on how irreversible the dynamical rules are. In the strongly irreversible phase, trajectories with differe…

Continuum mechanics of entanglement in noisy interacting fermion chains
Tobias Swann, Adam Nahum
We develop an effective continuum description for information scrambling in a chain of randomly interacting Majorana fermions. The approach is based on the semiclassical treatment…

Continuous symmetry breaking in 1D spin chains and 1+1D field theory
Adam Nahum
We argue that ground states of 1D spin chains can spontaneously break U(1) ``easy-plane'' spin rotation symmetry, via true long-range order of , at the phase transition…
