A translation-invariant (TI) bipolaron theory of superconductivity based, like Bardeen–
Cooper–Schrieffer theory, on Fröhlich Hamiltonian is presented. Here the role of Cooper …

High temperature superconducting theory drew controversy after the discovery of
superconductors at close to room temperatures. However, a consistent microscopic theory of …

An electron strongly coupled to the LO-phonon in an asymmetric quantum dot has been
considered. The system has a central impurity and it is under electric and magnetic fields …

The influence of electric field on the ground-state energy of a polaron, bound to a
hydrogenic impurity in a cylindrical quantum dot is investigated. The results illustrate the …

In this work, an electron which is strongly coupled to the LO-phonon in triangular quantum
dots with Coulomb impurity is considered. The eigenenergies and eigenfunctions of the …

In the present paper, the thermodynamics of three-dimensional impurity magnetopolaron
under strong parabolic potential is investigated. To this aim, we first analytically solved the …

In this paper, we investigate the time evolution of the quantum mechanical state of a polaron
using the Pekar type variational method on the electric-LO-phonon and the magnetic-LO …

In this paper, we calculate the time evolution of the quantum mechanical state of a bound
magnetopolaron in a modified cylindrical quantum dot. In the condition of strong coupling …

Using the Pekar variational method, the effects of the temperature, impurity and
electromagnetic fields on the transition are investigated through the eigenenergies of the …

The impurity states in a narrow-gap semiconductor parabolic quantum dot in the presence of
external extremely strong magnetic field are considered in adiabatic approximation …
