comment Is the density operator a mathematical convenience or a 'fundamental' aspect of quantum mechanics?
The Markov assumption is independent of the white noise assumption. And of the remaining of your comment. Indeed, one can always get rid of all non-Markovian features by enlarging the system. This is a mathematical theorem.

-1: It is easy to dismiss a 50 ears old paper. But try to do the same with the 2003 collection of articles cited in my answer!

comment EM wave function & photon wavefunction
@JiaYiyang: The right way to use Riemann-Silberstein vectorsin the context of field theory is to use them as labels of coherent states. This is close to the practice in quantum optics.
