非自伴量子磁哈密顿量离散谱的定量界

Quantitative bounds on the discrete spectrum of non self-adjoint quantum magnetic Hamiltonians

Diomba Sambou

摘要:

对某些数学物理算子的非自伴相对紧扰动建立了Lieb-Thirring型不等式.我们将所得结果应用于具有强度为$b\textgreater{}0$的恒定磁场的薛定谔和泡利量子哈密顿。特别是,我们使用这些界限,以获得一些信息的扰动运营商的本征值的分布在其本质谱的邻域。

英文摘要:

We establish Lieb-Thirring type inequalities for non self-adjoint relatively compact perturbations of certain operators of mathematical physics. We apply our results to quantum Hamiltonians of Schr{ö}dinger and Pauli with constant magnetic field of strength $b\textgreater{}0$. In particular, we use these bounds to obtain some information on the distribution of the eigenvalues of the perturbed operators in the neighborhood of their essential spectrum.
