“…Over recent years, applying the unitary transformation of Lee-Low-Pines type (UTLLPT) [44] and variational method of Pekar type (VMPT), [45,46] we have investigated some thermodynamic, electromagnetic and optical properties of QDs. [29][30][31][47][48][49][50][51][52][53][54][55][56][57] Al-though, in recent years, the Rashba effect [58][59][60] and magnetic field [61][62][63] influence of polaron in parabolic quantum dots have been studied, the temporal spatial distribution of the probability density (PD) and the influences of the RSOI and the temperature on the PD and the oscillating period (OP) of a parabolic QD (PQD) have not been accounted yet. In the present study, we mainly investigate the PD and OP in a PQD under the RSOI and temperature influences using the UTLLPT and VMPT.…”

We study the property of magnetopolaron in a parabolic quantum dot under the Rashba spin–orbit interaction (RSOI) by adopting an unitary transformation of Lee–Low–Pines type and the variational method of Pekar type with and without considering the temperature. The temporal spatial distribution of the probability density and the relationships of the oscillating period with the RSOI constant, confinement constant, electron–phonon coupling strength, phonon wave vector and temperature are discussed. The results show that the probability density of the magnetopolaron in the superposition of the ground and first excited state takes periodic oscillation (T 0/period) in the presence or absence of temperature. Because of the RSOI, the oscillating period is divided into different branches. Also, the results indicate that the oscillating period increases (decreases) when the RSOI constant, electron-phonon coupling strength and phonon wave vector (the confinement constant) increase in a proper temperature, and the temperature plays a significant role in determining the properties of the polaron.

“…Chen [21,22], one of the authors of this paper, employed the combination of these two methods to study Rashba effects on a bound polaron's first excited state and influences of the Rashba spin-orbit interaction on the period of bound polarons' oscillation in the quantum pseudodot, considering the temperature effect. For more information about this author's works on polarons, please refer to [23][24][25][26][27][28][29].…”

By a combination method of Lee–Low–Pines unitary transformation method and Pekar-type variational method, the ground state energy (GSE) of the bound polaron is studied in the asymmetrical Gaussian potential quantum well considering the temperature and electromagnetic field. The impacts of the temperature and asymmetrical Gaussian potential, electromagnetic field and phonon–electron coupling upon the GSE are obtained. The results show that the GSE of the bound polaron not only oscillates as the temperature changes regardless of the electromagnetic field and asymmetrical Gaussian potential and Coulomb impurity potential (CIP) and electron–phonon coupling but also has different rules with the electromagnetic field and asymmetrical Gaussian potential and CIP and electron–phonon coupling at different temperature zones.
