Electron pressure is a quantum mechanical phenomenon where electrons in a confined space exert a force due to their wave-like nature and the Pauli exclusion principle. It plays a crucial role in determining the structural stability and properties of materials, particularly in degenerate matter such as white dwarfs and neutron stars.

The Pauli Exclusion Principle, formulated by Wolfgang Pauli in 1925, states that no two fermions can occupy the same quantum state simultaneously within a quantum system. This principle is fundamental in explaining the structure of atoms and the behavior of electrons in atoms, leading to the diverse properties of matter.

Pauli exclusion principle

Structural stability refers to the property of a dynamical system where its qualitative behavior remains unchanged under small perturbations. It ensures that the system's critical features, such as equilibrium points and periodic orbits, are preserved, making it a fundamental concept in understanding the robustness of models in mathematics and physics.

Degenerate matter is a highly dense state of matter where quantum mechanical effects, particularly the Pauli exclusion principle, dominate the behavior of particles, typically electrons or neutrons. This state occurs in stellar remnants like white dwarfs and neutron stars, where gravitational forces have compressed matter to the point that classical physics no longer adequately describes its properties.

degenerate matter

White dwarfs are the remnants of stars that have exhausted their nuclear fuel and have collapsed into a dense, Earth-sized object composed mostly of electron-degenerate matter. They represent the final evolutionary state of stars not massive enough to become neutron stars or black holes, gradually cooling and fading over billions of years.

Neutron stars are the remnants of massive stars that have undergone supernova explosions, resulting in an incredibly dense object primarily composed of neutrons. They exhibit extreme gravitational and magnetic fields, and their study provides insights into fundamental physics and the behavior of matter under extreme conditions.
