Krylov complexity of a tilted extended Bose-Hubbard chain with Rydberg-dressed interactions
This research investigated how state-dependent information scrambling occurs in a quantum system called a tilted extended Bose-Hubbard chain with Rydberg interactions. Using Krylov complexity, the study found that competing interactions create unique chaotic features not seen in standard spectral analysis. This tool offers a new way to diagnose many-body chaos in quantum simulators.
