### What are the actual interactions between the Higgs field and fermions?

I understand the higgs field as the average of the electromagnetic spectrum at rest from which the big bang created noise, subsequent thought & the electromagnetic signal of intent (phi?=psi?). ...

### Fermi-Dirac Distribution for Multiple Species

The sum, $n_1 + n_2$, of two Fermi probabilities, as you call it, can exceed $1$ and therefore cannot be considered the correct probability. Instead, for the case of two independent ideal Fermi gases ...

### A confusion: Why are composite bosons possible?

This is a great question and something that confused me while studying superconductivity, where we often think of bound states of two electrons as a boson. I think the other answer and comments by ...

### A confusion: Why are composite bosons possible?

Consider a boson comprised of two fermions A and B. The boson has spin $0$. One way this can happen is one fermion is spin up and the other is spin down. Another way is A and B are mixtures of spin up ...

### Calculation of canonical partition function for fermion system with degenerate energy levels

I think LPZ already gave a very good answer, so here I'll just add a comment and a general picture. In some sense, you can say that this kind of problem is exactly one of the reasons you would like to ...

### Calculation of canonical partition function for fermion system with degenerate energy levels

In general it is easier to compute the canonical partition function from the grand canonical one. For a direct computation of the canonical ensemble, it is also easier to think in terms of orbitals ...
