Controlling Entanglement at Absorbing State Phase Transitions in Random Circuits
Controlling Entanglement at Absorbing State Phase Transitions in Random Circuits
Many-body unitary dynamics interspersed with repeated measurements display a rich phenomenology hallmarked by measurement-induced phase transitions. Employing feedback-control operations that steer the dynamics toward an absorbing state, we study the entanglement entropy behavior at the absorbing state phase transition. For short-range control operations, we observe a transition between phases with …
