摘要

研究抛物型量子线中极化子激发态的性质。采用线性组合算符法和Pekar变分法

导出了抛物量子线中强耦合和弱耦合两种情况下极化子的基态能量、第一内部激发能量、激发能和振动频率随量子线的约束强度的变化关系。数值计算结果表明:抛物型量子线中极化子的基态能量、第一内部激发能量、激发能和振动频率都随量子线约束强度的增强而增大

体现了量子线受限强度越大

相应的极化子的能量也越大。

Abstract

With the use of linear combination operator and the variational methods of Pekar type

the properties of the weak-and strong-coupling polarons excited state in parabolic quantum wires were studied. The ground state energy

the first internal excited energy and excited energy were calculated. Their dependence on the confinement strength of parabolic quantum wires was depicted. Numerical calculation indicated that the ground state energy

the first internal excited energy and the excited energy of the weak-and strong-coupling polaron in a parabolic quantum wire will increase with increasing of confinement strength

respectively.
