I find it difficult to believe that the canonical commutation relations for a complex scalar field are of the form
##[\phi(t,\vec{x}),\pi^{*}(t,\vec{y})]=i\delta^{(3)}(\vec{x}-\vec{y})##
##[\phi^{*}(t,\vec{x}),\pi(t,\vec{y})]=i\delta^{(3)}(\vec{x}-\vec{y})##
This seems to imply that the two scalar fields ##\phi## and ##\phi^{*}## are somehow coupled, even though they are not.
Can you explain this?
