What is Fermionic repulsion pressure described by quantum mechanics?

Fermions are particles with half spin for example, electrons. Pauli's exclusion principle states that no more than two fermions can occupy the same energy state. from Quantum mechanics, electrons will also fill up all energy levels until the Fermi Energy. If you compress these electrons further, the total fermi energy of the system is increased (not the individual fermions) and work must be done to compress these fermions. As a consequence, the fermions exert an opposing pressure, called the fermionic repulsion pressure.

In physics a quantum state with zero spin?

Fermions -- and that includes leptons and neutrinos -- all have a spin value of one-half. This is also true for every quark. Pions has zero spin.


What was Wolfgang Pauli's theory?

The Pauli exclusion principle is the quantum mechanical principle that says that 2 identical fermions (particles with half-integer spin) cannot occupy the same quantum state simultaneously.

What are fermions and bosons?

I think perhaps your confused here somewhat. A fermion is a particle which obeys the Pauli exclusion principle; put simply two fermions can not be in the same state (i.e. have the same set of quantum no's) at the same time. Fermions cannot be broken down into anything smaller, fermions include quark's, electron's, muon's, tau's and neutrino's which are elementary i.e. not made of anything but energy Quarks make up all other particles. Bosons can be made of 3 quarks and are split into two catergorys: Baryons such as Protons, Neutrons and many other heavy particles these are effectively composite fermions as they contain 3 quarks. Or Mesons, which contain one quark and an anti quark and hence are not composite fermions.
