Dirac's solution to this was to turn to the Pauli exclusion principle.

By the Pauli exclusion principle, no two particles can be in the same state.

This is the Pauli exclusion principle for many particles.

An important fact about fermions is that they follow a rule called the Pauli exclusion principle.

The number of electrons that can occupy each orbital is limited by the Pauli exclusion principle.

In these conditions, the structure of matter is supported by the Pauli exclusion principle.

The Pauli exclusion principle helps explain a wide variety of physical phenomena.

This is the first case of many-electron systems where the Pauli exclusion principle plays a central role.

The Pauli exclusion principle says that two electrons in one system cannot be in the same state.

This is equivalent to satisfying the Pauli exclusion principle.
