| 中文摘要: |
| 对于QPC实验中量子点Kondo单态的退相干强度,实验测量比理论预测大30倍的谜团至今尚未解决。本文利用格林函数方法,计算了QPC实验装置中量子点的输运特性,计算结果表明相移测量有可能是该谜团的原因之一。 |
| 英文摘要: |
| For the singlet decoherence intensity of quantum dot Kondo in the QPC experiment,the difference is thirty times between experiment measurement and theory calculation and the cause is undiscovered until now.In this paper,we calculate the transport properties of quantum dot on QPC equipment and find that the phase measurement is a possible cause about the mystery. |
