关于Vlasov-Schrödinger-Poisson系统的定态

On steady states for the Vlasov-Schrödinger-Poisson system

Younghun Hong, Sangdon Jin

摘要:

Vlasov-Schrödinger-Poisson系统是一个描述准低维电子气的动力学-量子混合模型。对于这个系统,我们构造了一个大类的2D动力学/1D量子定态在一个有界域作为广义自由能极小,我们证明了他们的有限子带结构,单调性,唯一性和条件动力学稳定性。我们的证明是基于集中-紧性原理,但由于缺乏源于混合性质的紧性,出现了一些额外的困难(见注1.9)。为了克服这些困难,我们引入了一个3-步细化的最小化序列的重排和部分最小化问题,和自由能(引理5.3)的davity引理是至关重要的。

英文摘要:

The Vlasov-Schrödinger-Poisson system is a kinetic-quantum hybrid model describing quasi-lower dimensional electron gases. For this system, we construct a large class of 2D kinetic/1D quantum steady states in a bounded domain as generalized free energy minimizers, and we show their finite subband structure, monotonicity, uniqueness and conditional dynamical stability. Our proof is based on the concentration-compactness principle, but some additional difficulties arise due to lack of compactness originated from the hybrid nature (see Remark 1.9). To overcome the difficulties, we introduce a 3-step refinement of a minimizing sequence by rearrangement and partial minimization problems, and the coercivity lemma for the free energy (Lemma 5.3) is crucially employed.
