Local measurements in quantum systems are projective operations which act to counteract the spread of quantum entanglement. Recent work has shown that local, random measurements applied to a generic volume-law entanglement generating many-body system are able to force a transition into an area-law phase. This work shows that projective operations can also force a similar classical phase transition; we show that local projections in a chaotic system can freeze information dynamics. In rough…

Dynamical entanglement transition in the probabilistic control of chaos

We uncover a dynamical entanglement transition in a monitored quantum system that is heralded by a N´eel order parameter. Classically, chaotic systems can be stochastically controlled onto unstable

Bridging the gap between classical and quantum many-body information dynamics

The fundamental question of how information spreads in closed quantum many-body systems is often ad-dressed through the lens of the bipartite entanglement entropy, a quantity that describes

Phase Transitions in Two-Dimensional Kauffman Cellular Automata

This work considers the random Boolean networks suggested by Kauffman mostly on a square lattice with nearest-neighbour interactions, and finds the phase transition observed in the overlap of configurations differing in the initial conditions is related to directed percolation on the body-centred cubic lattice.

Random Boolean networks: Analogy with percolation

Abstract Recent work on Kauffman's cellular automata and analogies with phase transitions in statistical physics is reviewed. We concentrate on nearest-neighbour models in square, honeycomb and
