    QM field separation "principle"

    I came across a term called "QM field separation "principle"" (or theorem, method etc.) and was left thinking, whether this is simply identifiable to general representation of fields (tensor ones typically) as a sum of their symmetric and antimetric components (like determining field properties by looking at it with respect to these 2 properties), or does it have something deeper in it ?

    I'm sorry to dissapoint u,but when you want an explanation to a notion,don't say "I came across...."and not state the exact words (the qoute really should imply an entire phrase,which should make sense),because,as i haven't heard of this principle u say (or maybe i have,but under other name),you'd leave the reader puzzling "Whatthe hell is that??"
    Anyway,it may have a connection with products of spinor representations of the restricted Lorentz group and the Clebsch-Gordan theorem,or it may not.

    Hoping u'd be taking my advice,

    Daniel.

    The whole issue surfaced in a discussion with a physics colleague at an airport running through a terminal :biggrin: (and I can't reach the guy for a couple of weeks or so).... so unfortunately it is a "came across" thing if there is one, without a really concrete reference. It's a bummer I know, but it's something I could use if it is a math tool developed and applied in the context. I haven't been able to link it to any theorem, so it's likely a representation ... got to dig.
