    For a dilute and nondegenerate relativistic spin- {1}/{2} system two kinds of Wigner functions are defined: one has sixteen spinor components and the other four spin components. Their relationship is established. Statistical expressions for the current density, the energy-momentum density and the spin density are obtained in terms of both kinds of Wigner by:   Application of the Wigner Distribution Function in Optics (M.J. Bastiaans) Introduction. Wigner distribution function as a local frequency spectrum. Examples of Wigner distribution functions. Properties of the Wigner distribution function. Ray spread function of an optical system. Transport equations for the Wigner distribution Edition: 1.

    This book presents quantum kinetic theory in a comprehensive way. The focus is on density operator methods and on non-equilibrium Green functions. The theory allows to rigorously treat. The Wigner quasiprobability distribution (also called the Wigner function or the Wigner–Ville distribution after Eugene Wigner and Jean-André Ville) is a quasiprobability distribution. It was introduced by Eugene Wigner in to study quantum corrections to classical statistical mechanics. The goal was to link the wavefunction that appears in Schrödinger's equation to a probability distribution in phase space. It is a generating function for all spatial autocorrelation functions .

      We calculate the Wigner function for massive spin-1/2 particles in an inhomogeneous electromagnetic field to leading order in the Planck constant ℏ. Going beyond leading order in ℏ we then derive a generalized Boltzmann equation in which the force exerted by an inhomogeneous electromagnetic field on the particle dipole moment arises naturally. It is developed in 3 directions: Landauer-like theory, kinetic theory and Green-Kubo linear response theory. This work generalizes the 2 directions of Landauer-like theory and the kinetic theory. Firstly, NEGF is used to derive phonon-phonon Hedin-like functional derivative equations which generates conserving self energy approximations for phonon-phonon : Paperback.

A new definition of the Wigner function for quantum fields coupled to curved space–time and an external Yang–Mills field is studied on the example of scalar and Dirac fields.

The definition uses the formalism of the tangent bundles and is explicitly covariant and gauge by: functions which are generated by the y-integrations. In general combining with the Maxwell equation, the quantum kinetic equation of Wigner function Eq.(4) is equivalent to the QED field theory.

In order to connect Eq.(4) with kinetic theory, one needs to obtain explicitly the equations of all elements of the Wigner function, which is a 4 × 4.

Rischke, Qun Wang. Here we give an introductory account of the wave kinetic theory. Its basic ingredients are the Wigner function and its evolution equation.

How to obtain a quantum kinetic theory. Covariant Wigner function Advantage: covariant theory. A new definition of the Wigner function for quantum fields coupled to curved space-time and an external Yang-Mills field is studied on the example of scalar and Dirac fields.

The definition uses the formalism of the tangent bundles and is explicitly covariant and gauge invariant. Derivation of collisionless quantum kinetic equations is carried out for both quantum fields by using the first. The function /(x, p, s) is hence a combination of a Wigner function in the phase space variables and the Q-function for the spin.

Equivalence with the density matrix formalism The construction above contains the same information as the density matrix, and the distribution function can be used to calculate the expectation value of any.

Recommended Books and Resources This lecture course covers three topics: kinetic theory, stochastic processes and linear response. Most decent books on statistical mechanics will have a section covering non-equilibrium topics in general.

However, if you’re looking for details beyond the basics, you’ll probably need a di↵erent book for.This book is an informative guide for researchers, and the benefits are a result from an integrated view of a very broad area of research, which is limited in previous books about this subject.
