Composite Quantum Systems |
In General
> s.a. Composite Systems [general theory, and internal degrees of freedom];
Individuality; quantum states;
spin models.
* Idea: Considering a quantum system
as composed of subsystems A and B means treating its Hilbert space
as the tensor product \(\cal H\) = \(\cal H\)A
⊗ \(\cal H\)B.
* Rem: The view that
the physical world forms a compositional hierarchy does not stand up
to a close examination of how physics has treated composition.
