Scaling of quantum Zeno dynamics in many-body systems
Scaling of quantum Zeno dynamics in many-body systems
We study the quantum Zeno effect (QZE) in two many-body systems, namely the one-dimensional transverse-field Ising model and the Lipkin-Meshkov-Glick (LMG) model, coupled to a central qubit.Our result shows that in order to observe QZE in the Ising model, the frequency of the projective measurement should be of comparable order …
