| __Quantum Dynamical Systems: Continuous Quantum Measurement__ *(Site not responding. Last check: 2007-10-12)* |

| | Since in **quantum** **mechanics** **measurement** creates an irreducible disturbance on the observed system, and we do not wish to disturb the system unduly, the desired **measurement** process must yield a limited amount of information in a finite time. |

| | In this project, aside from understanding such fundamental issues as **quantum** chaos, our aim is to further develop the theory of continuous **measurement** and apply it to systems of future technological importance such as in atom and **quantum** optics and **quantum** nanomechanics. |

| | The top panel on the right shows an example of a localized **quantum** trajectory situation for the particle position distribution as a function of position of a driven Duffing oscillator (strong **measurement**, 'classical' range of parameters, green curve) versus a nonlocalized one (weak **measurement**, '**quantum**' range of parameters, red curve). |
