Macroscopic Effects of Localized Measurements in Jammed States of Quantum Spin Chains
Résumé
A quantum jammed state can be seen as a state where the phase space available to particles shrinks to zero, an interpretation quite accurate in integrable systems, where stable quasiparticles scatter elastically. We consider the integrable dual folded model, which is equivalent to the model in the limit of large anisotropy. We perform a jamming-breaking localized measurement in a jammed state. We find that jamming is locally restored, but local observables exhibit nontrivial time evolution on macroscopic, ballistic scales, without ever relaxing back to their initial values.
