Quantum dynamics of simple systems

The effect of repetitive measurement for quantum dynamics of driven by an intensive external force of the simple few-level systems as well as of the multilevel systems that exhibit the quantum localisation of classical chaos is investigated. Frequent measurement of the simple system yields to the quantum Zeno effect while that of the suppressed quantum system, which classical counterpart exhibits chaos, results in the delocalisation of the quantum suppression. From the analysis we may conclude that continuously observable quasiclassical system evolves essentially classically-like.

We present a very simple system consisting in laser-cooled atoms interacting with a time-modulated standing laser wave. Such a system presents a quantum dynamics that can display different chaotic behaviors like quantum-chaos and quasi-classical chaos.
