Particle Production and Krylov Complexity of Circular Strings Near Black Hole Horizons
Infalling circular strings near black hole horizons show radial particle production and Krylov complexity that scales polynomially with initial position in the near-horizon thermal regime, with operator growth rate scaling linearly and supporting complexity-volume ideas.
