As well-known, it has been found that bosons are not subject to the Pauli Exclusion Principle. Then there is the question: whether or not that in some cases the exclusion principle is also invalid for fermions?

Pauli exclusion principle and the law of included multiple-middle

Current suppression in a small magnetic field can ultimately be traced back to the famous Pauli exclusion principle, the quantum mechanical principle that states that no two electrons (fermions) may have identical quantum numbers.

Following the Pauli exclusion principle, each configuration should not contain two or more identical single particle quantum states of the same Dirac particle.

The 14 chapters begin with the theory of relativity and continue through configuration of the atom, quantum state of atoms, electron spin, the Pauli exclusion principle, X-rays, and other topics, ending with a chapter on high-energy physics.

(3) For example, in chapter 2, he says "indistinguishability leads directly to the famous Pauli exclusion principle (not true--one also needs the fermionic nature of electrons) and in chapter 6, he tells us that an "elevator's acceleration due to gravity cancels the gravitational force, and the freely falling elevator becomes an inertial reference frame" (gravity--that is, the curvature of space--causes the acceleration, rather than canceling it; by "inertial frame" we usually mean a non-accelerating frame).
