Aharonov-Bohm量子环的电偶极矩振荡

Electric dipole moment oscillations in Aharonov-Bohm quantum rings

A. M. Alexeev, M. E. Portnoi

摘要:

预测和分析了单电子纳米环在平面内受磁通量作用下的电偶极矩磁振荡。这些振荡伴随着环中的级间光学跃迁的选择规则的周期性变化,从而允许控制相关联的太赫兹辐射的偏振特性。

英文摘要:

Magneto-oscillations of the electric dipole moment are predicted and analyzed for a single-electron nanoscale ring pierced by a magnetic flux (an Aharonov-Bohm ring) and subjected to an electric field in the ring's plane. These oscillations are accompanied by periodic changes in the selection rules for inter-level optical transitions in the ring allowing control of polarization properties of the associated terahertz radiation.
