具有均匀磁场的薛定谔算子的Eigenvalue界
Eigenvalue bounds for Schrödinger operators with a homogeneous magnetic field
摘要:
我们证明了二维和三维空间中具有均匀磁场的薛定谔算子的Lieb-Thirring不等式。这些不等式通过依赖于磁场强度的半经典近似来约束本征值的和,从而量化了系统的抗磁行为。对于均匀磁场中的谐振子,我们得到了不等式中的锐常数。
英文摘要:
We prove Lieb-Thirring inequalities for Schrödinger operators with a homogeneous magnetic field in two and three space dimensions. The inequalities bound sums of eigenvalues by a semi-classical approximation which depends on the strength of the magnetic field, and hence quantifies the diamagnetic behavior of the system. For a harmonic oscillator in a homogenous magnetic field, we obtain the sharp constants in the inequalities.
