A model for quantum Zeno effect based upon an effective SchrÃ¶dinger equation originated by the path-integral approach is developed and applied to a two-level system simultaneously stimulated by aâ€¦ (More)

We report on the measurement of the Casimir force between conducting surfaces in a parallel configuration. The force is exerted between a silicon cantilever coated with chromium and a similar rigidâ€¦ (More)

The evolution of a two-level system subjected to stimulated transitions which is undergoing a sequence of measurements of the level occupation probability is evaluated. Its time correlation functionâ€¦ (More)

Application of the path-integral approach to continuous measurements leads to effective Lagrangians or Hamiltonians in which the effect of the measurement is taken into account through an imaginaryâ€¦ (More)

onset of the drag force is shown for two different condensate densities, corresponding to maximum sound velocities of 4.8 mm/s (solid circles, left axis) and 7.0 mm/s (crosses, right axis). Theâ€¦ (More)

A model of repeated quantum measurements of magnetic flux in superconducting circuits manifesting tunneling is discussed. The perturbation due to the previous measurements of magnetic flux is alwaysâ€¦ (More)
