Wigner Molecules in Nanostructures
The one– and two– particle densities of up to four interacting electrons with spin, confined within a quasi one–dimensional “quantum dot” are calculated by numerical diagonalization. The transition from a dense homogeneous charge distribution to a dilute localized Wigner–type electron arrangement is investigated. The influence of the long range part of the Coulomb interaction is studied. When t...
متن کاملWigner function approach to nano device simulation
Coherent transport in mesoscopic devices is well described by the Schrödinger equation supplemented by open boundary conditions. When electronic devices are operated at room temperature, however, a realistic transport model needs to include carrier scattering. In this work, the kinetic equation for the Wigner function is employed as a model for dissipative quantum transport. Carrier scattering ...
متن کاملChemical Reactions Using a Non-Equilibrium Wigner Function Approach
A three-dimensional model of binary chemical reactions is studied. We consider an ab initio quantum two-particle system subjected to an attractive interaction potential and to a heat bath at thermal equilibrium at absolute temperature T > 0. Under the sole action of the attraction potential, the two particles can either be bound or unbound to each other. While at T = 0, there is no transition b...

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...
