论文摘要
报告的工作的目的是为限制在二次Hellmann潜力的相反的量子点光学特性提供新的见解。使用Nikiforov-Uvarov（NU）方法求解Schrödinger方程，以获得特征力和本征函数的分析表达式。使用密度矩阵形式主义研究了线性以及吸收系数和折射率的三阶非线性变化。吸收系数和折射率变化与结构参数和光学强度相关。
The aims of the reported work are to provide new insights into the quantum dot optical properties confined in an inverse of a quadratic Hellmann potential. The Schrödinger equation is solved using the Nikiforov-Uvarov (NU) method, in order to obtain the analytical expressions of the eigenenergies and the eigenfunctions. The linear together with the third-order nonlinear changes in absorption coefficients and refractive index are investigated using the density matrix formalism. The absorption coefficients and the refractive index changes are strong related to the structure parameters and the optical intensity.
