Phase-coherence time saturation in mesoscopic systems: wave function collapse
arXiv:cond-mat/0002188 · doi:10.1103/PhysRevB.62.R16291
Abstract
A finite phase-coherence time emerges from iterative measurement onto a quantum system. For a rapid sequence, the phase-coherence time is found explicitly. For the stationary charge conduction problem, it is bounded. At all order, in the time-interval of measurements, we propose a general expression for .
