The Quantum Zoo of Butterflies
Bin Yan (Los Alamos National Laboratory)
Abstract: Classical chaotic dynamics exhibit extreme sensitivity to initial conditions -- known as the butterfly effect. The problem in quantum mechanics, however, is much more subtle. Conventional approaches usually address quantum chaos in the energy domain, e.g., spectral correlations. Recently developments invented different diagnostics to reveal the quantum butterfly effect in the time domain. The quantum butterfly effect has a much richer structure than its classical counterpart. In this talk, I will tell a coherent story and introduce various types of butterflies in the quantum world: The famous Lorenz-Butterfly with circuit complexity; a Bradbury-Butterfly known as a novel correlator, the out-of-time correlator; and an Anti-Butterfly which can heal damaged information from the past.
