Remarks on the fact that the uncertainty principle does not
... A “simple” characterization of positivity for trace-class operators is still to be found. We have given one such characterization for a particular class of putative Wigner distributions (those dominated by a phase-space Gaussian). In the general case possibly the phase-space techniques and concepts ...

Who Invented the Copenhagen Interpretation? A Study in Mythology
... Heisenberg on the Copenhagen Interpretation (continued): If the system is closed, we may in some circumstances have, at least approximately, a “pure case,” and the system is then represented by a vector in Hilbert space. The representation is, in this particular case, completely “objective,” i.e. i ...
