U H F G Maxwell relations. The Fermi—Dirac and Bose—Einstein statistics give the energy level occupation as:. Additionally, the particles in this system are assumed to have negligible mutual interaction.

Not published in full until. The Fermi-Dirac distribution approaches the Maxwell-Boltzmann distribution in the limit of high temperature and low particle density, without the need for any ad hoc assumptions. For example, the electronic heat capacity of a metal at room temperature seemed to come from times fewer electrons than were in the electric current. The distributions of particles with the number estadistca ways each distribution can be produced according to Maxwell-Boltzmann statistics where each particle is presumed to be distinguishable.

F—D statistics was applied in by Ralph Fowler to describe the collapse of a star to a white dwarf. Estadistoca the particles are speeding around, they possess some energy. This problem is known as the Gibbs paradox. Identifying E as the internal energy, the Euler-integrated fundamental equation states that:. By assumption, the combined system of the system we are interested in and the reservoir is isolated, so all microstates are equally probable.

In order to maximize the expression above we esatdistica Fermat’s theorem stationary pointsaccording to which local extrema, if exist, must be at critical points partial derivatives vanish:.

For example, two particles may have different momenta i. The number of ways that a setadistica of occupation numbers n i can be realized is the product of the ways that each individual energy level can be populated:.

To get a distribution function of the number of particles as a function of energy, the average population of each energy state must be taken.

Retrieved from ” https: For example, distributing two particles in esatdistica sublevels will give population numbers of, or for a total of three ways which equals 3!

The variance in particle number due to thermal fluctuations may also be derived the particle number has a simple Bernoulli distribution:.

Fermi–Dirac statistics – Wikipedia

The result is the F—D distribution of particles over these states which includes the condition that no two particles can occupy the same state; this has a considerable effect on the properties of the system.

For a system of identical fermions with thermodynamic equilibrium, the average number of fermions in a single-particle state i is estadistifa by a logistic functionor sigmoid function: We maxwsll our solution fe Lagrange multipliers forming the function:.

If we now have a set of boxes labelled a, b, c, d, e, Pergamon Press,p. In the above discussion, the Boltzmann distribution function was obtained via directly analysing the multiplicities of a system. What follows next is a bit of combinatorial thinking which has little to do in accurately describing the reservoir of particles.

d The average for each of the 9 states is shown below, and the plot of estafistica averages as a function of energy. It is divided by the number of permutationsn! But there are ways to achieve the macrostate at right, so if every distribution is presumed to be equally likely, then the system is 30 times more likely to be found in the right hand macrostate.
