Zeno dynamics yields ordinary constraints
P. Facchi, S. Pascazio, A. Scardicchio, L. S. Schulman
abstract: The dynamics of a quantum system undergoing frequent measurements (quantum
Zeno effect) is investigated. Using asymptotic analysis, the system is found to
evolve unitarily in a proper subspace of the total Hilbert space. For spatial
projections, the generator of the "Zeno dynamics" is the Hamiltonian with
Dirichlet boundary conditions.
