Abstract

For the spin-boson model we numerically exhibit special microscopic initial states that evolve, under pure quantum dynamics, from one macroscopically well-defined state to another. This is unusual in that typical states of the model evolve to superpositions of macroscopically different states. Although the mathematical rationale for the existence of the special states is not clear, that existence reflects favorably on a proposed theory of quantum measurement.
