Effect of temperature on lifetime and energy states of bound polaron in asymmetrical Gaussian quantum well

Electromagnetic field effect on weak-coupling piezoelectric polaron in an asymmetrical Gaussian confinement potential quantum well

“…Consequently, many scientists devoted their investigations in the physical properties of small-sized quantum systems in the presence of external field [ 5 , 6 , 7 , 8 , 9 ]. QW with Gaussian potential is an effective theoretical model for describing real case, and has been extensively demonstrated by some theoretical and practical works in the last two decades [ 10 , 11 , 12 , 13 , 14 ]. There are also important other investigations dealing with different types of confinement potentials the hyperbolic potential [ 15 ], cylindrical potential [ 16 ] and parabolic potential [ 17 ].…”

Influence of temperature on ground state energy of bound polaron in asymmetric Gaussian potential quantum well in presence of electromagnetic field

“…In recent years, much attention has been paid to these two methods. For instance, Khordad et al [20], who considered a system under the condition of the asymmetrical Gaussian QW, explored the influence of the temperature on a bound polaron's GSE and lifetime by the LLPUTM and the PTVM. 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.…”

Effect of temperature and electric field on life time and energy states of bound polaron in triangular quantum dot

“…Khordad [14,15] have studied the first internal excited state energy and transition frequency of strong-coupling impurity bound polaron in a quantum pseudodot and Gaussian quantum well using the well-known Lee-Low-Pines (LLP) unitary transformation method. Using the same method, the heat capacity of a two electron quantum dot with parabolic confinement in magnetic field in the presence of electron-electron interaction, Dresselhaus spin-orbit interaction has been studied in [16].…”
