Based on the spatial periodic chaos synchronization in coupled ring and linear arrays, we proposed a random high-dimensional chaotic encryption scheme. The transmitter can choose hyperchaotic signals randomly from the ring at any different time and simultaneously transmit the information of chaotic oscillators in the ring to receiver through public channel, so that the message can be masked by different...
We study the dynamical localization in the system of a two-level Rydberg atom interacting exactly with a pulsed standing microwave. This system approaches an atom optics realization of usual delta-kicked rotor under the rotating-wave approximation (RWA). We find that the non-energy-conserving processes neglected in the RWA have a strong effect on the classical and quantum diffusion, which, compared...
