Schrodinger-泊松方程在至少3维空间中的半经典极限

Semi-classical limit of Schrodinger-Poisson equations in space dimension at least 3

Thomas Alazard, Rémi Carles

摘要:

我们证明了存在的解决方案的Schrodinger-Poisson系统的时间间隔独立的普朗克常数,当掺杂配置文件并不一定在无穷大,在次二次外部潜在的存在下。通过在Zhidkov空间中工作,在空间维度至少为3的情况下,解决了掺杂分布的可积性的缺乏。我们推断,主要的二次量(位置密度和修改后的动量密度)收敛强烈的普朗克常数为零。当掺杂分布是可积的,我们证明逐点收敛。

英文摘要:

We prove the existence of solutions to the Schrodinger-Poisson system on a time interval independent of the Planck constant, when the doping profile does not necessarily decrease at infinity, in the presence of a subquadratic external potential. The lack of integrability of the doping profile is resolved by working in Zhidkov spaces, in space dimension at least three. We infer that the main quadratic quantities (position density and modified momentum density) converge strongly as the Planck constant goes to zero. When the doping profile is integrable, we prove pointwise convergence.
