This density matrix formulation is not needed in cases of thermal equilibrium so long as the basis states are chosen to be energy eigenstates.

This is called an eigenstate of positionor, stated in mathematical terms, a "generalized position eigenstate (eigendistribution)".

In the novel a physical process in the human brain is responsible for collapsing quantum wavefunctions representing systems into particular eigenstates.

Superselection rules are postulated rules forbidding the preparation of quantum states that exhibit coherence between eigenstates of certain observables.

One particular example is the density matrix that characterizes the mixed state of a quantum system as a linear combination of elementary, pure eigenstates.

An atom in an excited energy eigenstate according to quantum mechanics is not in an energy eigenstate according to quantum field theory. Since the k-states can be thought of as a ' wave ' an eigenstate corresponding to a superposition of k-states is usually called a wavepacket. Below the quantum chaos border, such an eigenstate is very close to one quantum register state, while above this border it is composed of a huge number of them. This implies that no quantum state can be simultaneously both a position and a momentum eigenstate. From Wikipedia This example is from Wikipedia and may be reused under a CC BY-SA license.
