Consider a cylinder … WebNov 11, 2015 · 1 Answer. The degeneracy pressure is indeed due to one of the four fundamental forces, but it takes a bit of though to see why. If you put fermions into a box then their energy levels are quantised into the usual energy levels for a particle in a 3D box.

"Electron degeneracy pressure is a particular manifestation of the more general phenomenon of quantum degeneracy pressure. The Pauli exclusion principle disallows two identical half-integer spin particles (electrons and all other fermions) from simultaneously occupying the same quantum state. The result is an emergent pressure against compression of matter into smaller volumes of space. Electron degeneracy pressure results from the same underlying mechanism that defines the ele… " - Degeneracy pressure results from

WebElectron degeneracy pressure occurs when electrons are compressed into a very small volume. Since their positions are well-known, they gain a large momentum in accordance with Heisenberg's uncertainty principle. This momentum creates a pressure which is temperature-independent and can result in helium flash in stars. Electron degeneracy … Weba pressure, known as degeneracy pressure, which is able to counteract the gravitational pressure which is present in systems of high density like stars. This pressure can be approximated in both the non-relativistic and ultra-relativistic regimes and is given as an equation of state (EOS) relating the pressure and number/mass density. ...
