Entanglement phase transitions in measurement-only dynamics

M Ippoliti, MJ Gullans, S Gopalakrishnan, DA Huse… - Physical Review X, 2021 - APS
Unitary circuits subject to repeated projective measurements can undergo an entanglement
phase transition (EPT) as a function of the measurement rate. This transition is generally …

Eigenstate thermalization hypothesis
