Emergent anomalous hydrodynamics at infinite temperature in a long-range XXZ model
Emergent anomalous hydrodynamics at infinite temperature in a long-range XXZ model
The conventional wisdom suggests that transports of conserved quantities in nonintegrable quantum many-body systems at high temperatures are diffusive. Recent study suggests a potential counterexample of this paradigm. We independently complement this counterexample by directly uncovering anomalous infinite-temperature hydrodynamics in a spin-1/2 XXZ chain with power-law couplings. This model, classified …
