No measurement induced phase transition in the entanglement dynamics of monitored non-interacting one-dimensional fermions in a disordered or quasiperiodic potential

Antonio M. Garc\'ia-Garc\'ia, Can Yin, Fan Bo

Monitored non-interacting fermions in disordered or quasiperiodic potentials remain in an area-law entanglement phase for any monitoring strength.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

the critical monitoring strength is consistent with zero so no MIPT occurs... confirms the absence of the MIPT for any monitoring or disorder strength.

C2weakest assumption

That finite-size scaling with maximum lattice size L=18000 is sufficient to establish that the correlation length remains finite for any nonzero monitoring strength, and that the nonlinear sigma model mapping with mass term fully captures the monitored dynamics without missing relevant operators.

C3one line summary

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.
