温度对非对称量子点中强磁耦合极化子声子平均数的影响

Influence of temperature on the mean number of phonons for strong-coupling magnetopolaron in an asymmetric quantum dot

采用Huybrechts线性组合算符法和LLP变分法,研究了温度对非对称抛物量子点中强耦合磁极化子声子平均数的影响。数值结果表明,非对称量子点中强耦合磁极化子的声子平均数随温度的升高而减小。另外,温度还对磁极化子的声子平均数随量子点的横向受限强度、纵向受限强度、外磁场的回旋频率和电子-声子耦合强度的变化产生显著影响。

Influence of temperature on the mean number of phonons for strong-coupling magnetopolaron in an asymmetric quantum dot axe studied by using the Huybrechts＇ linear combination operator and the LLP variational method. Numerical results indicate that the mean number of phonons for strong-coupling magnetopolaron decreases with increasing temperature. The changes of the mean number of phonons of magnetopolaron changing with the transverse effective confinement strength, longitudinal effective confinement strength, cyclotron frequency and the electron-phonon coupling strength are strongly related to the temperature.
