Likewise, the wavefunction for N particles each with spin is:

Suppose there are M active sites to which N particles bind.

The model considers N particles in two containers.

The above discussion generalizes readily to the case of N particles.

Consider the operator algebra of a system of N identical particles.

A system of N independent particles, therefore, has the total of 3N degrees of freedom.

Consider a collection of N noninteracting particles, which can each be in one of two quantum states, and .

Consider a rigid body of N particles joined by rigid rods.

Maxwell asks us to consider the very same box with N particles in it.

An N-particle state belongs to a space of states describing systems of N particles.
