具有恒定磁场的Hartree方程:适定性理论

The Hartree equation with a constant magnetic field: Well-posedness theory

Xin Dong

摘要:

我们考虑无限多电子在恒定外部磁场作用下的Hartree方程。对于该系统,当初始数据是费米海的扰动时,我们给出了局部适定性结果,这是该系统的非迹类平稳解。在这种情况下,单粒子哈密顿量是泡利算子,它具有与拉普拉斯算子不同的性质,例如,它具有离散谱和无限维本征空间。新的成分是,我们使用的Fourier-Wigner变换和相关的Laguerre多项式的渐近性质,以获得一个崩溃的估计,我们建立的局部适定性结果。

英文摘要:

We consider the Hartree equation for infinitely many electrons with a constant external magnetic field. For the system, we show a local well-posedness result when the initial data is the pertubation of a Fermi sea, which is a non-trace class stationary solution to the system. In this case, the one particle Hamiltonian is the Pauli operator, which possesses distinct properties from the Laplace operator, for example, it has a discrete spectrum and infinite-dimensional eigenspaces. The new ingredient is that we use the Fourier-Wigner transform and the asymptotic properties of associated Laguerre polynomials to derive a collapsing estimate, by which we establish the local well-posedness result.
