In Quantum Mechanics, a system of
particles with internal spin degrees of freedom
is described by a wave function which in the position representation reads
|

|
(1.1) |
Here,
is the probability density for finding particle 1 at
with spin quantum number(s)
, particle 2 at
with spin quantum number(s)
,... etc. Note that for spin
, one would choose for
one of the spin projections, e.g.
.
Remark: Usually, many-particle wave functions and the issue of indistinguishability are discussed in the position representation.
