Hi, when we consider an N-particle (assume non-interacting) system, say putting them in a box; why do we always say the states of the system (e.g. when counting them to find the "density of states as function of energy") are just the products of single particle stationary states (i.e. energy eigenstates)(maybe symmetrized or antisymmetrized as appropriate) and not count superpositions of single-particle states as independent states of the system? Thanks
