Multiple quantum particles

    So why is it that if you have a system with two distinguisable particles why is their state vector written as


    what's this product? Is this product still "in" the original hilbert space?

    I think the state is in the tensor product of the particle spaces.

    Huh, is that so, I'll have to play around with that idea and see where it takes me. Thanks SelfAdjoint.

    The state |a>|b> is also called a "direct product state", and this basic idea is discussed in most books on linear algebra.
