The Pauli Exclusion Principle: A Pillar of Quantum Mechanics

The Pauli Exclusion Principle, also known as the Pauli Principle or the Principle of Exclusion, is a fundamental concept in quantum mechanics formulated by Austrian-Swiss physicist Wolfgang Pauli in ۱۹۲۵. The Pauli Exclusion Principle states that no two electrons—or more generally, no two identical fermions—can occupy the same quantum state simultaneously (for example, be in the same place at the same time). This principle plays a crucial role in understanding various phenomena, from elementary particles to the structure of stars. According to this principle, no two electrons in an atom can have the same set of quantum numbers. It is therefore essential to consider the concept of quantum numbers, which are assigned to each electron or quantum state and vary based on type, spin, vibration, and rotation. In physical interpretation, the principle states that two particles cannot occupy the same location at the same time. This article is a review of the Pauli Exclusion Principle. The research was conducted using a library-based approach.
