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…

Spacetime picture for entanglement generation in noisy fermion chains
Tobias Swann, Denis Bernard, Adam Nahum
Studies of random unitary circuits have shown that the calculation of Renyi entropies of entanglement can be mapped to classical statistical mechanics problems in spacetime. In thi…

Nonlinear sigma models for monitored dynamics of free fermions
Michele Fava, Lorenzo Piroli, Tobias Swann +2
We derive field theory descriptions for measurement-induced phase transitions in free fermion systems. We focus on a multi-flavor Majorana chain, undergoing Hamiltonian evolution w…
