Large-scale numerics up to 18000 sites and nonlinear sigma model analysis demonstrate that monitored non-interacting 1D fermions in disorder or quasiperiodicity exhibit only area-law entanglement with no MIPT at any monitoring strength.
GPU-enabled simulations at L=16384 (1D) and 160x160 (2D) confirm no MIPT in 1D but a finite-rate MIPT in 2D with ν≈1.3, partially disagreeing with NLSM predictions.

Absence of measurement- and unraveling-induced entanglement transitions in continuously monitored one-dimensional free fermions
Replica Keldysh analysis shows monitored 1D free fermions exhibit area-law entanglement beyond an exponentially large scale ln(l_φ,*) ~ J/[γ cos(φ)], with no genuine measurement- or unraveling-induced entanglement transitions.
