Spectra of Interacting Electrons in a Quantum Dot: Quasi-Exact Solution
摘要:
我们提出了一个程序来解决的薛定谔方程的两个相互作用的电子在量子点中的外部磁场的存在下,在准精确可解的光谱问题。我们表明,可以恢复特定值的磁场,这导致一个准确的确定的本征值和本征函数的哈密顿量的对称性。我们证明了该问题具有一个隐藏的sl_2-代数结构。
英文摘要:
We present a procedure to solve the Schroedinger equation of two interacting electrons in a quantum dot in the presence of an external magnetic field within the context of quasi-exactly-solvable spectral problems. We show that the symmetries of the Hamiltonian can be recovered for specific values of the magnetic field, which leads to an exact determination of the eigenvalues and eigenfunctions. We show that the problem possesses a hidden sl_2-algebraic structure.
