@article{Maimbourg2020BathInducedZL, title={Bath-Induced Zeno Localization in Driven Many-Body Quantum Systems.}, author={Thibaud Maimbourg and Denis M Basko and Markus Holzmann and Alberto Rosso}, journal={Physical review letters}, year={2020}, volume={126 12}, pages={ 120603 } }

We study a quantum interacting spin system subject to an external drive and coupled to a thermal bath of vibrational modes, uncorrelated for different spins, serving as a model for dynamic nuclear polarization protocols. We show that even when the many-body eigenstates of the system are ergodic, a sufficiently strong coupling to the bath may effectively localize the spins due to many-body quantum Zeno effect. Our results provide an explanation of the breakdown of the thermal mixing regime…
