A relativistic variant of the Wigner function
The Wigner function is a quasiprobability density over phase space (for reviews, see Lee[1], Cohen[2], or Hillery et al.[3]; a quasiprobability is generally not positive semi-definite), so in a quantum field theory setting it is not manifestly Lorentz covariant. Quasiprobabilities are conceptually interesting partly because Arthurs-Kelly type interpretations of positive definite Husimi function...
متن کاملRelativistic Wigner Function, Charge Variable and Structure of Position Operator
We consider the relativistic Wigner representation for a class of observables which are arbitrary combinations of the standard coordinate and momentum operators (independent of the charge variable). One should take into account the fact that eigenfunctions of the standard operator of coordinate contain both charge components, although the real physical states are not chargeviolating. The evolut...
متن کاملModular Localization and Wigner Particles
We propose a framework for the free field construction of algebras of local observables which uses as an input the Bisognano-Wichmann relations and a representation of the Poincaré group on the one-particle Hilbert space. The abstract real Hilbert subspace version of the Tomita-Takesaki theory enables us to bypass some limitations of the Wigner formalism by introducing an intrinsic spacetime lo...
متن کاملWigner function for damped systems
Both classical and quantum damped systems give rise to complex spectra and corresponding resonant states. We investigate how resonant states, which do not belong to the Hilbert space, fit the phase space formulation of quantum mechanics. It turns out that one may construct out of a pair of resonant states an analog of the stationary Wigner function.
متن کاملTransition in the Equilibrium Distribution Function of Relativistic Particles
We analyze a transition from single peaked to bimodal velocity distribution in a relativistic fluid under increasing temperature, in contrast with a non-relativistic gas, where only a monotonic broadening of the bell-shaped distribution is observed. Such transition results from the interplay between the raise in thermal energy and the constraint of maximum velocity imposed by the speed of light...
