Subdiffusive transport in the Fredkin dynamical universality class
Catherine McCarthy, Hansveer Singh, Sarang Gopalakrishnan +1
We identify a pseudolocal conserved charge in the Fredkin and Motzkin quantum spin chains and explore its consequences for the hydrodynamics of systems with Fredkin- or Motzkin-typ…

Mixed-state learnability transitions in monitored noisy quantum dynamics
Hansveer Singh, Romain Vasseur, Andrew C. Potter +1
We consider learnability transitions in monitored quantum systems that undergo noisy evolution, subject to a global strong symmetry -- i.e., in addition to the measuring apparatus,…
