Why do only the eigenstates of the Hamiltonian follow a boltzman distribution

Suppose I had a system with e.g. conserved impulse p, but no thermal equilibrium/fixed energy. Why is only the entropy of the distribution of eigenstates of the hamiltonian being maximized? (if p and …

Entropy driven production of antimatter at high temperatures

Might be a stupid question: The condition for spontaneous change under constant pressure is dH - T*dS < 0. If one took a bunch of matter and heated it to a arbitrarily high temperature, would 50% of t …
