Measurement-induced phase transitions in disordered fermions
The study investigates measurement-induced phase transitions (MIPT) in a d-dimensional disordered fermionic system subject to continuous local particle density monitoring. By deriving an effective field theory, the authors found that quenched disorder modifies the model parameters but does not change the fundamental nature of the transition. The resulting nonlinear sigma model suggests disorder enlarges the area-law regime, shifting entanglement transitions to weaker measurement rates.
