Fermi-dirac Statistics (Noun)
Meaning
(physics) law obeyed by a systems of particles whose wave function changes when two particles are interchanged (the Pauli exclusion principle applies).
Classification
Nouns denoting cognitive processes and contents.
Examples
- Fermi-Dirac statistics is a statistical distribution that applies to particles that have half-integer spin, such as electrons and protons in an atom.
- The Pauli exclusion principle is a fundamental aspect of Fermi-Dirac statistics, which states that no two particles can occupy the same quantum state simultaneously.
- In Fermi-Dirac statistics, the probability of a particle being in a particular state is inversely proportional to the exponential of the energy of that state.
- Fermi-Dirac statistics is used to describe the behavior of electrons in a solid, where the electrons are treated as a gas of particles that obey the Pauli exclusion principle.
- The Fermi-Dirac statistics distribution is used to calculate the thermal properties of a system, such as the specific heat and the entropy of a solid.
