Dynamical Fractal in Quantum Gases with Discrete Scaling Symmetry

Author(s): Chao Gao, Hui Zhai, and Zhe-Yu Shi
Inspired by the similarity between the fractal Weierstrass function and quantum systems with discrete scaling symmetry, we establish general conditions under which the dynamics of a quantum system will exhibit fractal structure in the time domain. As an example, we discuss the dynamics of the Loschm...
