Distinguishability Transitions from Global Quantum Snapshots
Catherine McCarthy, Sarang Gopalakrishnan, Romain Vasseur
Quantum states generated by generic time evolution are locally featureless: local measurements return random outcomes that are identical for all states. However, global snapshots i…
Weak integrability breaking perturbations in classical integrable models on the lattice
Sara Vanovac, Catherine McCarthy, Federica Maria Surace +1
We show how to systematically construct weak integrability breaking perturbations (WIBs) for classical integrable models on the lattice. These perturbations, which allow quasi-cons…
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…
Slow crossover from superdiffusion to diffusion in isotropic spin chains
Catherine McCarthy, Sarang Gopalakrishnan, Romain Vasseur
Finite-temperature spin transport in integrable isotropic spin chains (i.e., spin chains with continuous nonabelian symmetries) is known to be superdiffusive, with anomalous transp…
