The approach based on the Wigner function is considered as a viable model of quantum transport which allows. in analogy with the semiclassical Boltzmann equation. to restore a description in the phase-space. A crucial point is the determination of the Wigner function at the equilibrium which stems from the equilibrium density function. https://www.animationbengal.com/?w=quick-buy-yale-bulldogs-law-school-discount-great-price
