Measurement-induced quantum diffusion
arXiv:quant-ph/9901028 · doi:10.1103/PhysRevLett.83.61
Abstract
The dynamics of a kicked quantum system undergoing repeated measurements of momentum is investigated. A diffusive behavior is obtained even when the dynamics of the classical counterpart is not chaotic. The diffusion coefficient is explicitly computed for a large class of Hamiltonians and compared to the classical case.
