The  paper of  the  month,  chosen  by  the Editor-in-Chief,  is  "Temperature and Impurity Effects on Strongly Coupled Polaron in an Asymmetric Parabolic Potential Quantum Dot"  by H.-J. Li and S.-P. Shan;

DOI: 10.12693/APhysPolA.147.46

The present is devoted to polarons, observed in various systems. Despite the fact that polarons in solids have attracted interest for decades, new insights continue to emerge in this research area. This paper concentrates on spin-orbit splitting in asymmetric potentials. The dependence of the spin-dependent effective mass on temperature is analyzed. The effects of electron-phonon coupling strength, polaron velocity, transverse and longitudinal confinement lengths, and the strength of the Coulomb binding potential on the polaron effective mass are discussed through numerical calculations. A thorough physical discussion of the obtained results is provided.

This paper is of great interest to all physicists specializing in condensed matter physics.
