What Is Quantum Chaos?

In classical mechanics, chaos refers generally to seemingly random random-like motions that occur in a certain system. According to the corresponding principle, there should be quantum irregular motion in quantum mechanics, that is, chaos. At present, there is no sufficient evidence to prove that this exists in quantum mechanics ^[1] .

Quantum chaos

Right!

In classical mechanics,

In classical mechanics ^[2]

May 1993, M, IBM Research Center, Almaden, California. F. Crommie et al. Conducted a "quantum fence" experiment. The principle is that the interference between the incident surface state electron waves and the electron waves scattered from iron atoms will form a standing wave around the iron atoms, which will cause the density of the surface local electronic states. Variety. Similarly, the dipole force of light on atoms can be used to irradiate laser light as a fence light on atoms in the Bose Einstein condensate to observe the phenomenon of quantum chaos
