The study identifies a new class of strongly disordered fixed points emerging due to non-unitarity in a monitored disordered XX spin chain via an RSRG-X approach on a mapped non-Hermitian ladder.
It is described by dimerization of the chain: the even and odd bonds lie on different distributions, and the distance from criticality (i.e

Measurement-Induced Phase Transition in a Disordered XX Spin Chain: A Real-Space Renormalization Group Study
The study identifies a new class of strongly disordered fixed points emerging due to non-unitarity in a monitored disordered XX spin chain via an RSRG-X approach on a mapped non-Hermitian ladder.
