Abstract:
We show that Mumford's Approximate Macroscopic Unique (AMU) states exist for quantum systems consisting of selfadjoint operators when the commutators are small. In particular,
AMU states always exist in position and momentum systems when the Planck constant ? is sufficiently small. However, we show that these standard mechanical systems are far away
from classical mechanical (commutative) systems even when ?>0
