Quartic Anharmonicity in Different Spatial Dimensions
G. V. Efimov, G. Ganbold
A path-integral method effective beyond the perturbation expansion approach is suggested to consider the quartic anharmonicity in different spatial dimensions. Due to an optimal re…

The polaron confined in one dimension
G. Ganbold
The ground-state energy, the effective mass and the number of virtual phonons of the optical large polaron confined strictly in one dimension have been estimated by using the gener…

Quasi-particle characteristics of the one-dimensional polaron
G. Ganbold
The main quasi-particle characteristics of the one-dimensional polaron are estimated within and beyond the most general Gaussian approximation at arbitrary electron-phonon coupling…
