Fundamental characteristic property of particles which together with orbital angular momentum acts as the generator of rotations and which doesn't have a classical equivalent but is sometimes compared to and contrasted with classical intrinsic angular momentum.

Yes, the factorizability is an axiom. Formally, it is states as The Hilbert space of a composite system is the Hilbert space tensor product of the state spaces associated with the component syst …
If I understand your question correctly, there seems to be a misunderstanding in your statement As far as I understand, in quantum mechanics, you can identify any spin half particle to be fermion …
The addition rule has an absolute value sign. That is $$s_{tot}= |s_1 + s_2|,|s_1 + s_2 - 1|, \ldots, |s_1 - s_2|$$ And so the smallest value you can have is $1/2 - 1/2 = 0$. $s_{tot}$ is the th …
Your equation for $| \psi \rangle$ is \begin{equation} |\psi\rangle = \frac{1}{\sqrt{6}}\left(2\big\uparrow\big\uparrow\big\downarrow - \big\downarrow\big\uparrow\big\uparrow - \big\uparrow\big\ …
Since it appears you are actively working on the problem I will offer a series of hints. Please comment if you need further guidance. Hint 1: Muonium is a bound state of $\mu^+ e^-$. Note that they …
For completeness I'll summarize the answer here. After a fun conversation in the comments, we saw that it will be more illuminating to write H=-\sum_ {i=1}^{N-1} \sigma_i^x \sigma_ {i+1} ^x + h \ …
