Abstract | We deal with the classical limit of the Schrodinger-Poisson system to the Vlasov-Poisson equations as the Planck constant epsilon goes to zero. This limit is also frequently called the "semiclassical limit." The coupled Schrodinger-Poisson system for the wave functions {psi(j)(epsilon)(t, x) is transformed to the Wigner-Poisson equations for a "phase space function" f(epsilon)(t, x, epsilon). For the case of the so-called completely mixed state, i.e., j = 1, 2,..., infinity, under additional assumptions on the potential, this classical limit was solved in 1993 by P.-L, Lions and T. Paul in [23] and, independently, by P. A. Markowich and N. J. Mauser in [26] with strong assumptions on the initial data. The so-called pure state case, where only one or a finite number of wave functions {psi(j)(epsilon)(t, x)} are considered, has been open up to now. We prove here for general initial data (the pure-state as well as the mixed-state case) of the wave functions in one space dimension that the Wigner measure f(t, x, epsilon), which is a weak limit of f(epsilon)(t, x, epsilon) as c tends to 0, satisfies the classical one-dimensional Vlasov-Poisson equations. As a by-product, we have improved the decay assumption on the initial data of one-dimensional Vlasov-Poisson equations in [38] for the existence of global weak solutions with measures as initial data. The equations we regard are widely used in quantum/classical transport and semiconductor theory as a nonlinear one-particle ("mean field") approximation of the linear N-electron Schrodinger/Hamilton equation. |
